Expand pear, media, experimental, state, and messaging modules

Add manual API helpers across categories: pear runtime/embed/runner/spawn,
preflight cancel, update gossip history, headless UI pipe helpers, media
origin weights and latency paths, experimental void/tension/time-capsule,
CRDT conflict-set and grow-only-set, job dispatcher peek, trust graph decay,
session rotateAll, topic channel batch unsubscribe, fulltext searchOr, FEC
batch encode, marketplace cheapest listing, and noise session closeAll.
