* feat(reedy): wire RetrievalBackend interface + metrics into the chat adapter
Phase 1B backend integration. Adds a RetrievalBackend interface so
TauriChatAdapter holds a uniform reference instead of branching across the
file, with two impls — LegacyIdbBackend (wraps the existing IDB ragService
unchanged) and ReedyBackend (lazy-opens reedy.db, adapts the active
provider's embedding model to Reedy's narrower shape, exposes a Vercel
`lookupPassage` tool). selectBackend() gates Reedy behind both
aiSettings.reedy.enabled AND isTauriAppPlatform() per plan D15 so the MVP
cohort is desktop-only.
The Reedy path streams via streamText({ tools: { lookupPassage }, stopWhen:
stepCountIs(3) }) with a status-aware system prompt that tells the model
how to phrase responses for each RetrieverStatus value.
Replaces the module-global `lastSources` + 500ms poll with a per-instance
ReedySourceStore keyed by a synthetic per-turn id the adapter generates,
so the Sources dropdown stops racing on global state. Both legacy and
Reedy backends now feed citations through the same store; the UI is
backend-agnostic via a shared SourceItem shape both ScoredChunk and
RetrievedChunk satisfy.
Adds the reedy_metrics table to the reedy migration (versioned with
app_version + session_id + turn_id per row) plus a ReedyMetrics writer
that ReedyBackend uses to record indexing-lifecycle and tool-use events.
Always-on local; no network egress. NoopReedyMetrics keeps construction
cheap before the DB opens.
Tests: retrievalBackend selectBackend gates, ReedySourceStore semantics
(append/replace/subscribe/clear), ReedyMetrics debounced batching +
exportBundle, and a TauriChatAdapter contract test that asserts the
Reedy/legacy code-paths pass the right args to streamText.

* feat(reedy): UI wiring — settings toggle, clickable sources, feedback bundle
Phase 1B UI integration. AIAssistant now constructs the active backend
(legacy or Reedy) via selectBackend with the platform gate from M1.7,
wires a ReedySourceStore for the chat adapter, and routes Sources-dropdown
clicks to `getView(bookKey)?.goTo(source.cfi)` when the source has a CFI.
Legacy-path sources still render as static rows because they have no CFI.
AIPanel grows a 'Reedy Retrieval (Beta)' BoxedList with the toggle and a
'Send Reedy feedback' button that calls exportReedyMetricsBundle and
triggers a JSON download of the last 90 days of events. The toggle is
disabled on web with an explanatory description per plan D15.
Thread accepts an onSourceClick callback and renders each source as a
button when its source carries a CFI, otherwise as a static div — so the
Sources dropdown is backend-agnostic via the shared SourceItem shape.
