fix: add coerceToSafeValue to cell renderers at source, use getCellRenderer in HeaderHighlight

[Copilot]

Cell renderers (NumberCellRenderer, CurrencyCellRenderer, etc.) crashed with React error #310 when receiving non-primitive values from the API — MongoDB wrapper types ({$numberDecimal}), expanded reference objects, arrays of objects. The original issue also requested type-aware formatting in highlight fields, responsive column capping, performance optimizations, and metadata-driven configuration.

Cell renderer safety (@object-ui/fields)

• Added coerceToSafeValue() — coerces MongoDB types ($numberDecimal→Number, $oid→String, $date→String), expanded references (extract name/label/_id), arrays→comma-joined strings, Date→ISO string
• Applied in all renderers: Number, Currency, Text, Percent, Date, Lookup, Email, Phone, URL, Formula
• All consumers (tables, highlights, forms) benefit — fix is at the renderer level, not a consumer workaround

// Before: raw object passed as React child → error #310
const formatted = typeof value === 'number' ? ... : value;

// After: safe coercion at renderer entry
const safe = coerceToSafeValue(value);
// { $numberDecimal: "250000" } → 250000
// { _id: "x", name: "Acme" } → "Acme"
// [{ name: "Alice" }, { name: "Bob" }] → "Alice, Bob"

HeaderHighlight type-aware rendering

• Uses getCellRenderer with objectSchema enrichment (type, options, currency, precision, format)
• Removed previous direct-formatting workaround — renderers are now safe at source

autoLayout responsive column capping

• inferDetailColumns(fieldCount, containerWidth?) — <640px→1col, <900px→max 2col; backward-compatible when omitted

Activity panel collapse-when-empty

• RecordChatterPanel gains collapseWhenEmpty prop, passed through to RecordActivityTimeline

DetailSection progressive batch rendering

• VirtualScrollOptions interface (enabled, batchSize, itemHeight) with VS_REVEAL_DELAY-based deferred reveal

RecordDetailView optimizations

• detailSchema wrapped in useMemo with granular deps
• Hardcoded HIGHLIGHT_FIELD_NAMES removed — reads exclusively from objectDef.views.detail.highlightFields

Tests: 134 targeted tests passing (16 coerceToSafeValue + 14 HeaderHighlight + cell renderer suites); 599 total across all related packages.

<issue_description>## 合并优化 Issue：DetailView/RecordDetailView 代码架构与体验提升

1. HeaderHighlight 高亮区类型感知展示

• 问题：高亮栏金额等字段未格式化，直接 String(value) 渲染，丢失货币、枚举等类型语义。
• 建议：使用 getCellRenderer 进行类型感知展示。例如金额要格式化为 $250,000.00；stage 等枚举字段可用 Badge。已传递 type 信息，只需在 HeaderHighlight.tsx 内处理。

3. RecordDetailView 生成 detailSchema 需 useMemo 优化

• 问题：每次渲染都重新组装 detailSchema 对象，导致无谓 re-render，影响性能。
• 建议：用 useMemo 包裹 detailSchema，依赖 objectDef、pureRecordId、related、childRelatedData、actionRefreshKey。

4. autoLayout 列数推断需考虑容器宽度（响应式优化）

• 问题：autoLayout 目前只按字段数量推断列数，iPad/手机等窄屏下易出现 3 列紧密排布，影响可读性。
• 建议：在 inferDetailColumns 增加对容器宽度的感知，或采用 CSS Container Query/useMediaQuery。宽度 <640px 强制1列，<900px 最多2列，其余按原逻辑。

6. Activity/Chatter 面板空状态折叠

• 问题：底部无评论时 Activity 面板依然常显，占用大量页面空间。
• 建议：为 RecordChatterPanel/RecordActivityTimeline 传入 collapseWhenEmpty/defaultCollapsed 实现空状态自动收起。

7. DetailSection 虚拟化渲染

• 问题：单一 section 字段多时全量挂载影响渲染性能。
• 建议：引入虚拟滚动配置（virtualScroll），在大字段数量时分批渲染/回收 DOM，提高性能。可用 @object-ui/react/usePerformance 已支持该配置。

8. HIGHLIGHT_FIELD_NAMES 元数据化

• 问题：高亮字段名硬编码于代码中，不同业务��象场景下不适用。
• 建议：完全取自 objectDef.views.detail.highlightFields 配置，没有 fallback。

Root cause: getCellRenderer routes highlight values through renderers like NumberCellRenderer, which does typeof value === 'number' ? ... : value — when the value is a plain object (e.g. MongoDB Decimal128 {$numberDecimal}, expanded refs), the raw object gets passed as a React child → error #310.

Fix in 7cf936a: Added OBJECT_SAFE_TYPES guard in HeaderHighlight. Before passing values to a CellRenderer, plain objects are checked — only renderers that natively handle objects (lookup, user, owner, file, image) receive them. Others get a safely-extracted string (value.name || value.label || value._id || JSON.stringify(value)).

2 new tests added covering the object-value guard and lookup passthrough. All 331 tests passing.

The feature named virtualScroll is actually progressive/deferred batch rendering: it renders the first batch, waits 100ms, then renders all remaining fields at once. True virtual scrolling involves windowing (only rendering items visible in the viewport and recycling DOM nodes). The current naming may mislead consumers into thinking DOM recycling or viewport-based rendering is happening.

Consider renaming to deferredRender or progressiveRender to better communicate the actual behavior, or alternatively documenting clearly in the interface JSDoc that this is not windowed virtual scrolling.

[Copilot]

The visibleCount state is initialized as undefined, meaning the first synchronous render mounts all fields (since renderedFields falls through to layoutFields when visibleCount is undefined). Only after the useEffect fires does it set visibleCount to batchSize, causing a second render with the batch. This defeats the purpose of reducing the initial render cost — all 50 fields are mounted on the first paint, then immediately unmounted and re-mounted with only the batch.

To actually reduce initial render cost, initialize visibleCount eagerly based on the props:

const [visibleCount, setVisibleCount] = React.useState<number | undefined>(() => {
  if (virtualScroll?.enabled && section.fields.length > (virtualScroll.batchSize ?? 20)) {
    return virtualScroll.batchSize ?? 20;
  }
  return undefined;
});

This ensures the first render only mounts the batch.

Suggested change

	const [visibleCount, setVisibleCount] = React.useState<number | undefined>(undefined);
	const [visibleCount, setVisibleCount] = React.useState<number | undefined>(() => {
	if (virtualScroll?.enabled && section.fields.length > (virtualScroll.batchSize ?? 20)) {
	return virtualScroll.batchSize ?? 20;
	}
	return undefined;
	});

[Copilot]

The useMemo dependency array only lists [objectDef.name, pureRecordId, childRelatedData, actionRefreshKey], but the memo body captures several locally computed variables that are re-derived every render: primaryField, sections, related, highlightFields, sectionGroups, recordHeaderActions, and objectDef.label. Since these are plain const assignments (not themselves memoized), the useMemo will return a stale schema whenever only those upstream values change.

Additionally, the ROADMAP at line 1438 documents the deps as including objectDef and related, which doesn't match the actual code.

Consider either (a) including the missing variables in the dependency array, or (b) individually memoizing the intermediate values (sections, primaryField, etc.) and including those in the useMemo deps. Suppressing the lint rule here is hiding a real correctness gap.

[Copilot]

The collapseWhenEmpty logic computes defaultCollapsed at mount time and passes it to useState, which only uses the value once. When items is initially [] (as in RecordDetailView where feedItems starts empty and is populated asynchronously), the panel will start collapsed and stay collapsed even after comments load — because no useEffect syncs the collapsed state when items transitions from empty to non-empty.

Consider adding an effect that auto-expands the panel when collapseWhenEmpty is true and items changes from empty to non-empty, e.g.:

React.useEffect(() => {
  if (collapseWhenEmpty && items.length > 0) {
    setCollapsed(false);
  }
}, [collapseWhenEmpty, items.length]);

Suggested change

	const [collapsed, setCollapsed] = React.useState(defaultCollapsed);
	const [collapsed, setCollapsed] = React.useState(defaultCollapsed);
	const prevItemsLengthRef = React.useRef(items.length);
	React.useEffect(() => {
	if (!collapseWhenEmpty) {
	prevItemsLengthRef.current = items.length;
	return;
	}
	const prevLength = prevItemsLengthRef.current;
	// Auto-expand when items transition from empty to non-empty
	if (prevLength === 0 && items.length > 0) {
	setCollapsed(false);
	}
	prevItemsLengthRef.current = items.length;
	}, [collapseWhenEmpty, items.length]);

[Copilot]

The itemHeight property is declared in VirtualScrollOptions but is never read or used anywhere in the implementation. This is misleading for consumers who might expect it to control actual virtual scrolling behavior. Either remove the unused property or document it as reserved for future use. If it's intended for a future true-virtualization implementation (with windowing), consider marking it with a @deprecated or @reserved JSDoc tag.

[Copilot]

The ROADMAP states "17 new" tests while the PR description says "14 new tests total." Counting the new tests in the diffs: 7 (autoLayout) + 3 (RecordChatterPanel) + 6 (HeaderHighlight) + 3 (DetailSection) = 19 new tests. Please reconcile the test counts to be accurate.

[Copilot]

The ROADMAP documents the useMemo deps as objectDef, pureRecordId, related, childRelatedData, actionRefreshKey but the actual implementation at RecordDetailView.tsx:436 uses objectDef.name, pureRecordId, childRelatedData, actionRefreshKey — neither objectDef (the whole object) nor related are in the real dependency array. Please update the ROADMAP to match the actual implementation (or fix the implementation to match the intended deps).

The root cause was that getCellRenderer returns full React component renderers (NumberCellRenderer, LookupCellRenderer, etc.) designed for table cells, which may not safely handle ALL data shapes from the API (MongoDB types, nested objects, arrays of objects, etc.).

Fixed in 23350ed: Replaced getCellRenderer entirely with direct value formatting:

• All values pass through toSafeString() first, which coerces objects → strings, arrays → comma-joined strings
• Currency/number/percent use formatCurrency/Intl.NumberFormat/formatPercent directly
• Select/status fields render as <Badge> with JIT-safe COLOR_CLASS_MAP
• No CellRenderer components are used, so no possibility of error Fix CRM example field naming to comply with snake_case convention #310 regardless of data shape

All 333 tests passing (14 HeaderHighlight tests covering object values, arrays, and edge cases).

You're right — the proper fix is at the cell renderer level, not working around them in HeaderHighlight.

Fixed in 9e2b980: Added coerceToSafeValue() utility in @object-ui/fields that safely coerces MongoDB types ({$numberDecimal} → Number), expanded references (→ extract name/label/_id), arrays, and Date objects to primitives. Applied it in 10 cell renderers at the source: NumberCellRenderer, CurrencyCellRenderer, PercentCellRenderer, TextCellRenderer, EmailCellRenderer, UrlCellRenderer, PhoneCellRenderer, FormulaCellRenderer, DateCellRenderer, DateTimeCellRenderer.

HeaderHighlight now uses getCellRenderer again — since the renderers themselves are safe, no workaround needed. 16 new tests verify object-value safety in the renderers directly.
