feat: Obsidian 1.13 declarative settings + traverse_note builder (4.13.0-beta.3)

[michaelpporter]

Summary

• Implements getSettingDefinitions() on BreadcrumbsSettingTab for Obsidian 1.13's declarative settings API — page-based navigation, global settings search, proper hide() lifecycle
• Keeps existing display() as fallback for Obsidian < 1.13.0 (minAppVersion stays 1.12.3)
• Fixes Plugin.settings accessor conflict from Obsidian 1.13.0 adding settings?: unknown to the base class
• Compacts the Edge Fields settings UI: groups merged inline, spacing tightened, move-up/down arrows added
• Adds traverse_note explicit edge builder — DFS walk of vault links from a root note

What changed

src/settings/SettingsTab.ts

• Added ImpSettingPage, SvelteSettingPage, PageViewsSettingPage helper classes
• Added getSettingDefinitions() with full section structure: Edge fields, Implied relations, Edge sources (7 sub-pages including Traverse notes), Views (4 sub-pages), Commands (4 sub-pages), Suggestors, Debug

src/main.ts

• Replaced get/set settings accessor with declare settings: BreadcrumbsSettings
• loadSettings() calls reactive_settings.init() then this.settings = reactive_settings.current

src/components/settings/EdgeFieldSettings.svelte

• Groups row merged inline with field row; "Add to Group" dropdown → + button (Obsidian Menu)
• Spacing tightened with <hr> separator between items
• Move-up/down arrow buttons (splice-based reorder, correct when name filter is active)

src/graph/builders/explicit/traverse_note.ts (new)

• DFS over app.metadataCache.resolvedLinks starting from any note with BC-traverse-note-field: <field>
• Generates one edge per parent→child hop, typed with the specified field
• Registered in src/const/graph.ts, src/graph/builders/explicit/index.ts, settings, and migration tests

package.json / manifest.json / manifest-beta.json — bumped to 4.13.0-beta.3

obsidian dev dependency — upgraded from 1.12.3 → 1.13.0

Test plan

• Open plugin settings in Obsidian 1.13+ — confirm page-based navigation renders all sections
• Open plugin settings in Obsidian < 1.13 — confirm flat display() fallback still works
• Global settings search finds settings by name
• Edge fields: group chips inline, + button opens group menu, arrows reorder correctly
• Add BC-traverse-note-field: down to a note with wikilinks — rebuild graph — edges appear in Tree/Matrix views
• All 200 unit tests pass (bun run test)
