Move four DDD tensions on the Feed aggregate to ground:
- #1 The aggregate now holds a domain FeedState (camelCase) instead of the
snake_case FeedConfig DTO; infrastructure/feed-mapper.ts owns the
FeedState<->FeedConfig/FeedListItem translation as the sole snake_case site
outside the HTTP edge.
- #3 Replace the edit() recomputeExpiry control flag with a Lifetime VO:
passing a lifetime recomputes expiry, omitting it preserves the current one
(the dashboard quick-edit path).
- #4 Domain events carry their own feedId; dispatchFeedEvents centralizes the
drain+dispatch in the application layer (no more manual pullEvents at call
sites), keeping infra->application dependency direction intact.
- #6 Rename FeedId.fromTrusted to FeedId.unchecked to make the absence of
revalidation explicit.
Adds Lifetime + feed-mapper round-trip tests. 353 tests green, tsc clean,
wrangler dry-run OK. Docs (CLAUDE.md) synced.
