feat(ttp): E.3.14 worker bootstrap (insert + ttp.tagged publish)

Inner loop drains a per-process asyncio.Queue populated by one pump
task per topic in _TOPICS, dispatches each event through
CompositeTagger, persists via repo.insert_tags(), and publishes
ttp.tagged + per-technique ttp.rule.fired.<id> only when the insert
returned a non-zero rowcount.

CompositeTagger seeded with all six lifters (Behavioral, Intel,
CanaryFingerprint, Email, Identity, Credential).

Loop-prevention invariant from TTP_TAGGING.md §"Bus topics" enforced:
N replays of the same upstream event publish exactly one ttp.tagged
event. test_worker_bus covers both the direct invocation path and
the idempotency replay path.

Intel catch-up via attacker.session.ended is intentionally deferred
to E.3.14b — needs a session→intel join the repo doesn't expose yet.
