Fix all Windows-specific test failures caused by path handling problems
and EBUSY errors from unclosed SQLite database handles.
Root causes fixed:
1. POSIX path assumptions: replaced hard-coded file:///tmp, /repo, etc.
with pathToFileURL/path.resolve/path.join computed expectations
2. shortenPath() now normalizes backslashes to forward slashes after ~
and respects home directory boundaries
3. HistoryStorage.resetInstance() leaked its Database — added #close()
that finalizes all prepared statements and closes the DB
4. AgentStorage gained the same resetInstance()/#close() pattern
5. SqliteAuthCredentialStore.close() leaked one-off prepared statements
from inline this.#db.prepare() calls — wrapped each in try/finally
6. model-cache.ts used a process-global DB even for custom dbPath —
now opens/closes per-call via withModelCacheDb
7. createAgentSession leaked AuthStorage on construction failure —
added ownsAuthStorage cleanup in catch block
8. MnemopiBackend.removeDbFiles() now truly best-effort (catches errors)
9. TempDir retry window expanded from 4x10ms to 40x25ms
10. TempDir prefix convention: non-@ prefixes created dirs relative to
cwd instead of os.tmpdir() — all test temp dirs now use @ prefix
11. Shell-escaped interpolated paths in bash tool tests
12. git core.autocrlf false in autoresearch test repo init
All 522 previously-failing Windows tests now pass.
- Removed early FTS-only return so prefix and substring matches merge.
- Sorted merged results globally by prompt recency before limiting.
- Added /force, /copy, and /shake tips.
- Added `providerRetryWait` and `retryWait` hooks to stream/usage options so tests bypass real scheduler delays.
- Parameterized GitHub Copilot poll intervals and Copilot model retry base delay for fast test execution.
- Replaced `Bun.sleep`/`setTimeout` polling loops with `AbortSignal` event listeners in agent session tests.
- Consolidated auth-gateway E2E helpers into a shared `test/helpers` module, eliminating duplicated `checkGatewayAvailable` implementations.
- Migrated credential-disabled tests from SQLite-backed stores to an in-memory store, removing temp-dir lifecycle overhead.
- Fixed query tokenization to split on non-alphanumeric runs, aligning with FTS5 unicode61 indexer so punctuation-delimited terms like `git-commit` match correctly.
- Added LIKE-based substring fallback so infix queries FTS5 prefix matching cannot reach (e.g. `mit` matching `commit`) still return results.
- Merged FTS and substring results with deduplication, prioritizing FTS matches before substring-only matches up to the requested limit.
