- Handle::close aborts its chromiumoxide driver task when another
Arc<Browser> outlives the call, so shutdown returns instead of
hanging on a stream that never terminates. Generic close_or_abort
helper with regression tests covering both Arc paths.
- daemon.shutdown() is wrapped in a 5s timeout in main as defense
in depth.
- Default RUST_LOG silences chromiumoxide::conn / chromiumoxide::handler
WS-deserialize ERROR spam.

LaunchOptions::from_env() and LaunchOptions::default() now return
BrowserMode::Headless. The in-process daemon (via CrawlerConfig::from_env)
and the standalone crawler binary both pick this up — no display
required for production runs, smaller resource footprint.
`Headed` stays as an explicit opt-in via CRAWLER_BROWSER_MODE=headed
for debugging or sites that fingerprint headless Chrome. New unit test
locks the default in place.

The backend now boots an internal crawler daemon that runs a daily
metadata pass (CRAWLER_DAILY_AT in CRAWLER_TZ, advisory-lock guarded
for multi-replica safety) and drains SyncChapterContent jobs from
crawler_jobs through a worker pool. Chromium launches lazily on first
job and is torn down after CRAWLER_IDLE_TIMEOUT_S seconds of inactivity.
Modules:
- crawler::browser_manager — lazy-launch / idle-teardown wrapper
around browser::Handle, with an on_launch hook that re-injects
PHPSESSID on every fresh Chromium spawn.
- crawler::pipeline — run_metadata_pass (the shared discover/upsert
/cover/sync-chapters loop) and the enqueue_bookmarked_pending helper
used by the cron tick.
- crawler::daemon — cron task + worker pool, behind two trait seams
(MetadataPass, ChapterDispatcher) so tests can inject stubs without
standing up Chromium or a live source.
Behavior:
- CRAWLER_DAEMON=false skips daemon spawn entirely (default for tests).
- Catch-up tick fires on startup if the last persisted slot was missed.
- A SyncOutcome::SessionExpired sets a sticky AtomicBool; workers
idle until operator restart with a refreshed PHPSESSID.
- Worker dispatch wrapped in catch_unwind so a panicking handler
marks the job failed instead of taking down the worker.
- Migration 0015 adds a small crawler_state k-v table for the
last_metadata_tick_at watermark.
Dep additions: chrono-tz (IANA TZ parsing).
CLI (bin/crawler) reuses pipeline::run_metadata_pass and now holds
the browser via BrowserManager so the on_launch session injection
flow stays in one place. Inline chapter-content sync semantics are
unchanged — the queue is for the daemon, force-refetches and manual
backfills still bypass it.

- TargetSource: first concrete impl of the Source trait, modeled on
the old Puppeteer crawler's selectors (+ status normalization,
tag-count stripping, chapter list)
- DiscoverMode::Backfill walks pagination last->1, reverse within each
page (oldest-first); Incremental walks forward
- RateLimiter (tokio-time aware) plumbed through FetchContext so the
pagination walk honors the same per-host budget as the outer loop
- repo::crawler: ensure_source, upsert_manga_from_source (returns
New/Updated/Unchanged + current cover_image_path for backfill
decisions), sync_manga_chapters, mark_dropped_mangas — all
transactional, with case-insensitive lookups and source-insertable
genres
- Cover image download via reqwest+infer; stored under
mangas/{id}/cover.{ext} via the Storage trait
- Single CRAWLER_PROXY env wires both Chromium (--proxy-server) and
reqwest::Proxy::all (HTTP/HTTPS/SOCKS5)
- Crawler binary: positional start URL or $CRAWLER_START_URL,
$CRAWLER_LIMIT (cap fetches + skip drop pass on partial runs),
$CRAWLER_SKIP_CHAPTERS (disable selector AND sync), $CRAWLER_RATE_MS
- Silences chromiumoxide 0.7's known CDP deserialize log spam via
default tracing filter + CdpError::Serde downgrade
- 9 sqlx integration tests + 11 selector/rate-limit unit tests
