Rafael Dias Zendron d415baa026 fix(6848): auto-cleanup for telemetry tables causing OOM (#6988)
* fix(6848): add auto-cleanup for telemetry tables that grow without bound

Add retention-based cleanup for 4 tables that had no prune policy:
- domain_cost_history (timestamp INTEGER, unix epoch)
- compression_cache_stats (created_at DATETIME)
- xp_audit_log (created_at TEXT)
- compression_run_telemetry (timestamp INTEGER, unix epoch)

All default to 30-day retention, integrated into runAutoCleanup()
which runs on startup + every 6h via startCleanupScheduler().
Also runs VACUUM after startup cleanup to reclaim disk space.

6 unit tests covering retention boundary, no-op on recent data,
and DEFAULT_DATABASE_SETTINGS key existence.

Closes #6848

* ci: retrigger CI for Electron Package Smoke flaky test

* ci: retrigger flaky integration test (batch-e2e timeout)

* test(#6848): rewrite tests to call real cleanup functions with seeded DB data

Replace mock-only assertions with integration-style tests that seed data
into the isolated test DB, call the actual cleanup functions from
src/lib/db/cleanup.ts, and verify rows are correctly deleted.

All 6 tests now exercise real code paths:
- cleanupDomainCostHistory: verify old rows deleted, recent preserved
- cleanupCompressionCacheStats: verify old rows deleted, recent preserved
- cleanupXpAuditLog: verify old rows deleted, recent preserved
- cleanupCompressionRunTelemetry: ensure table + verify cleanup
- Combined: all 4 functions return 0 deletions when data is within retention
- DEFAULT_DATABASE_SETTINGS: verify new retention keys exist with value 30

* test(#6848): self-contained DATA_DIR isolation for the cleanup test

Builds on the existing rewrite (already correctly importing and calling
the real cleanupDomainCostHistory/cleanupCompressionCacheStats/
cleanupXpAuditLog/cleanupCompressionRunTelemetry from src/lib/db/cleanup.ts
with real seeded-row assertions instead of re-implementing the DELETE
inline) and closes the remaining gap: DATA_DIR isolation relied entirely
on the test:unit harness's `--import ./tests/_setup/isolateDataDir.ts`,
which is invisible from the test file itself.

Per CONTRIBUTING.md/CLAUDE.md, a single test file is documented to run
directly as `node --import tsx/esm --test tests/unit/<file>.test.ts` —
without the harness's isolation import, getDbInstance() resolves to the
developer's real ~/.omniroute/storage.sqlite, and this file's DELETE-based
cleanup calls operate on real rows, not test rows. Confirmed by running it
that way before this fix: it deleted 238 real compression_cache_stats rows
and 53 real xp_audit_log rows (assertions failed on the row counts, which
is how the gap surfaced) instead of the 2/3 rows the test itself inserted.

Fix: mkdtempSync + DATA_DIR override before the first src/lib/db/* import
(self-contained, matches the pattern in
tests/unit/duckduckgo-vqd-429-misclassification-6996.test.ts), plus
test.after() calling resetDbInstance() and removing the temp dir — the
repo's DB-test-cleanup rule (a dangling handle can hang the native test
runner). Re-ran after the fix: same 6/6 pass, now against an isolated
/tmp DB with the expected 3/2/3/2 row counts, in ~3s instead of ~15s.

Red-first proof: reset cleanupDomainCostHistory's cutoff to a no-op
(`cutoffEpoch = 0`, never matches a real row) — the dedicated
"cleanupDomainCostHistory: deletes rows older than retention window" test
failed as expected; restored and reran clean (6/6).
