Add unit tests for the profileRecency backfill and recent-profiles read
path that kill the language-mutation survivors: status-tip confirmation
(no tip, exact tip), exclusion of addresses without a profile, replies,
and polls, malformed addrPostHeight entries, missing optional stores,
seen/height defaulting, stale-record removal, and the height/seen/address
comparator tie-breakers. Tighten the indexer recency tests the same way
and assert the set-profile text and max-size boundary.
Refresh the mutate4javascript manifests and write the gherkin-mutator
acceptance mutation metadata for the changed features.

Indexer: maintain a profileRecency index keyed by address with the newest
confirmed qualifying post (top-level 0x6d02 or topic message 0x6d0c).
Replies and poll creations do not qualify, and mempool (unconfirmed) posts do
not write the index. Setting a profile after posting establishes recency from
the address's existing addrPostHeights, excluding replies and polls.
DB: GET /profile/recent now orders profiles by their most recent qualifying
post (height desc, seen desc, address asc) from profileRecency plus per-page
profile lookups, so it no longer scans addrPostHeights or sorts the whole
profiles store. Add a profileRecency backfill library and CLI that rebuilds
the index from addrPostHeights, posts, postParents, polls, and status,
ignoring unconfirmed entries and removing stale records.
Add focused unit tests, acceptance fixtures, and regex step handlers.
