MechaCat02 655ea42731 fix(crawler): scope dispatch_target to live sources, newest first (0.36.4) ...

The chapter dispatcher's URL resolver had no dropped_at filter and no
ORDER BY — a chapter whose only chapter_sources row had been soft-
dropped was still dispatched against the stale URL, eating retry
budget on guaranteed transients. With multiple live sources the LIMIT
1 winner was nondeterministic.

Add `AND cs.dropped_at IS NULL` and `ORDER BY cs.last_seen_at DESC`
to dispatch_target, bringing it in lockstep with the enqueue queries
in pipeline.rs that already filter on dropped_at. Returns None when
all sources are dropped — callers in daemon.rs already treat None
as "ack the job, skip the work."

Tests in tests/repo_chapter.rs cover the three branches (freshest
live wins, dropped sources skipped, all-dropped returns None).
