v2.1.0 — Coverage gate raised to 75%; storage and resilience test suites

What's New

Test Coverage: 40% → 77%

Coverage gate raised from 40% to 75% (currently passing at 77%). Enforced in both CI and local pytest runs.

tests/test_storage_extended.py — 27 real-SQLite tests via tmp_path (no mocks):

• Schema verification (magnets + scrape_runs tables)
• add_magnet: insert, count, duplicate idempotency
• has_hash: true/false/case-insensitive
• recent(limit=N): count and ordering
• search(): FTS match and empty-string passthrough
• stats(): today, last_7_days, last_30_days keys
• record_scrape_run: row insertion and value correctness
• WAL probe: succeeds on local filesystem path

tests/test_resilience_extended.py:

• retry.py: _parse_retry_after with valid/invalid/absent header; 429 uses header wait time
• migrate.py: _parse_line valid/invalid; migrate() no-files, single file, deduplication, wrong filename pattern, multi-file
• security.py: log_security_event write path and OSError suppression; _rotate_log_if_needed trim logic; _migrate_credentials v1→v2 upgrade; get_base_dir branch

Result

273 tests passing. 77% coverage. mypy clean. ruff clean.
