v0.16.0

Summary

This release redesigns the AI-agent diff-node UI and exposes the toolbar plugin's state and action helpers as a public API. It also fixes the package build under pnpm 11 by migrating hoist configuration to pnpm-workspace.yaml.

Breaking Changes

None. All changes are additive — existing exports remain.

Features

• rich-ext-ai-agent: Redesigned diff-node UI built on a dedicated node-state model and an imperative diff-node controller. New public exports: projectAgentDiffNodesToFactualState, and types AgentDiffNodePayload, AgentDiffOpType.
• rich-plugin-toolbar: Toolbar state and action helpers are now public — useToolbarState, INITIAL_TOOLBAR_STATE, applyBlockType, applyFontFamily, getBlockType, BLOCK_TYPE_LABELS, FONT_FAMILIES, getFontLabel, plus ToolbarButton/ToolbarDropdown/ToolbarSeparator and types BlockType, FontFamilyDef, ToolbarState.

Bug Fixes

• build: Migrate pnpm hoist config to pnpm-workspace.yaml for pnpm 11. pnpm 11 stopped reading public-hoist-pattern from .npmrc and the pnpm field from package.json; react/react-dom are now public-hoisted so transitive deps (tunnel-rat via @excalidraw/excalidraw) resolve react when rich-compose bundles the standalone litexml-html-preview-client.

Bump rationale

Shared version, highest-wins across changed packages.
