Julien Herr 23dd0a0c96 refactor(domain): purify the Feed aggregate (Track D — points 1, 4, 6b)
Remove the infrastructure Env leak and ambient time from the domain core, and
model the sender policy as a value object.

- Point 1: Feed.create/edit no longer receive Env. The application layer resolves
  the effective lifetime (parsing FEED_TTL_HOURS and applying the server override)
  via feed-service.resolveTtlHours and hands the domain a plain ttlHours.
  resolveExpiresAt(ttlHours, now) is now pure.
- Point 4: introduce a Clock port (systemClock default), injected at
  create/reconstitute. The aggregate uses clock.now() instead of Date.now().
  The isExpired edge helper keeps its Date.now() default for routes.
- Point 6b: extract SenderPolicy value object built once from the lists
  (decide(senders)) instead of re-parsing per sender; applySenderPolicy is now a
  thin wrapper over it.

Coverage moved with the logic: the FEED_TTL_HOURS override is now pinned by
feed-service.test.ts; aggregate tests use an injected fixed clock.

351 tests pass; tsc --noEmit clean.
