Huang Xin a1046f5684 feat(reedy): Phase 1A — MVP retrieval primitives (#4293)
* feat(db): add reedy schema migration with Tantivy FTS + lazy embeddings

Registers a new `reedy` migration set bound to reedy.db. Creates
reedy_book_meta + reedy_book_chunks with a Tantivy FTS index on
chunks.text (ngram tokenizer) and a per-book position index used by
BookRetriever. The vector embeddings table is intentionally NOT created
here — the indexer creates it lazily on first index so the vector32(<dim>)
column matches the active embedding model. Tests cover the migration
applies cleanly, is idempotent, and that the FTS index is queryable.

* feat(reedy): retrieval primitives — DB, chunker, indexer, retriever, lookupPassage tool

Wires the MVP retrieval pipeline behind reedy.db, all under src/services/reedy/
and with no integration into the existing AI module yet (Phase 1B will do that).

- ReedyDb wrapper over DatabaseService: book-meta CRUD, lazy embeddings
  table at the active model's dim, bulk chunk + embedding writes via batch(),
  hybridSearch (brute-force cosine + Tantivy FTS + reciprocal-rank fusion
  with 3× per-path over-fetch), per-book and global wipe. Internal write
  queue serializes batch() calls so Turso's single-writer transaction guard
  doesn't trip when BookIndexer runs across books in parallel.
- CfiChunker: TreeWalker over the section's DOM, ~maxChunkSize windows with
  paragraph > sentence > word break-points, full epubcfi(/6/N!/…) anchors,
  round-trip verified via CFI.toRange before each chunk lands.
- BookIndexer: per-book mutex, lazy embeddings-table creation, model.batchSize
  embedding batches with dim assertion, terminal status transitions
  (indexed | empty_index | failed). Re-indexing clears prior chunks via a new
  ReedyDb.clearBookChunks helper.
- BookRetriever: status-typed results (ok | not_indexed | empty_index |
  stale_index | degraded). Embedding has a 5s wall-clock budget; on timeout
  it falls through to FTS-only with status=degraded.
- lookupPassage Vercel ai-SDK tool: Zod-validated query/topK, per-turn
  composite-key dedupe, parallel-call serialization, 10s per-turn budget,
  6000-char result clamp, status-with-hint passthrough, and a separate
  serializeForModel that wraps each passage in <retrieved trust="untrusted">
  with XML-escaped content so book text cannot escape the envelope.

59 unit tests; pnpm test + pnpm lint clean.

Huang Xin 2d819b476c fix(db): forward DatabaseOpts to tauri-plugin-turso (#4292)
* fix(db): forward DatabaseOpts to tauri-plugin-turso

NativeDatabaseService.open ignored its opts parameter, dropping any
experimental feature flags (e.g. 'index_method' needed for FTS / vector
indexes) and any encryption config before they could reach the Tauri
plugin. Translate DatabaseOpts to the plugin's LoadOptions shape and
forward as the single argument Database.load accepts. Skip translation
when no relevant opts are set so the existing path-string call shape is
preserved for callers without experimental/encryption needs.

* test(db): cover Turso vector primitives + add benchmark harness

Verifies the Turso functions Reedy retrieval depends on, with a
brute-force per-book kNN test that runs against every DatabaseService
backend (node, native, WASM):

  SELECT vector_distance_cos(embedding, vector32(?)) AS d
    FROM book_chunks
   WHERE book_hash = ?
   ORDER BY d ASC LIMIT k

This is the path Turso's own founder recommended in
tursodatabase/turso#3778 ("First, focus on efficient SIMD-accelerated
brute-force search") and what shipped at commit 1aba105df4f. Native
vector index modules don't exist in this engine: `libsql_vector_idx`,
`vector_top_k`, and `USING vector/hnsw/diskann/ivfflat` all parse-error
against @tursodatabase/database@0.6.0-pre.28 (libsql_vector_idx is a
libSQL/sqld fork feature; DiskANN was closed not-planned upstream in
#832). The test asserts cross-book isolation and nearest-first ordering
using only `WHERE book_hash = ?` and `ORDER BY` — no DDL, no identifier
interpolation, no index plumbing.

Also adds bench/ harness for manual perf checks:

  pnpm bench [name]            run benchmarks (refuses in CI)
  pnpm bench --list            list available benchmarks
  pnpm bench --no-record       skip results.jsonl append
  pnpm bench --force           override the CI guard

Uses Node 24's --experimental-strip-types so no tsx devDep is needed.
Appends one JSON line per run to bench/results.jsonl (gitignored, local
history; share by pasting tabular stdout into PRs/issues). Explicitly
NOT in CI — shared-tenant variance makes synthetic-benchmark regression
detection unreliable; production telemetry (reedy_metrics, plan §M1.9)
is the right tool for that.

First benchmark: vector-retrieval. Measured on M1 Pro:
  400 chunks ×  384 dim  →  0.35 ms / query
  400 chunks ×  768 dim  →  0.45 ms / query
  2000 chunks × 768 dim  →  2.23 ms / query
  10000 chunks × 768 dim → 14.00 ms / query
  400 chunks × 1536 dim  →  0.70 ms / query

Per-chunk cost ~1.1 µs at 768 dim = ~1.4 ns/dim. NEON-class on
Apple Silicon, ~50× faster than scalar — confirms SIMD acceleration is
active in 0.6.0-pre.28. Per-query latency stays sub-ms at Reedy MVP
corpus sizes; the ceiling is ~10K chunks per book before phone-class
hardware notices.

Huang Xin 13588b4a65 chore(testing): add Tauri integration tests and E2E test infrastructure (#3483)
Set up WebDriver-based testing for the Tauri app with two tiers:
- Vitest browser-mode tests (*.tauri.test.ts) running inside the Tauri WebView
  for plugin IPC testing (libsql, smoke tests)
- WDIO E2E tests (*.e2e.ts) for UI-level interaction testing

Key changes:
- Add webdriver Cargo feature gating tauri-plugin-webdriver
- Add runtime capability for remote URLs (webdriver builds only)
- Add vitest.tauri.config.mts and wdio.conf.ts connecting to embedded
  WebDriver server on port 4445
- Add shared tauri-invoke helper for IPC from Vitest iframe context
- Add testing documentation in docs/testing.md
