chore: refresh graphify map and tidy AGENTS.md (#84)

graphify update regeneration: semantic hashes now populated in manifest.json, graph rebuilt (1634 nodes, 3179 edges). Track the map (5 curated files + .graphify_root) so a fresh checkout starts with it; cost.json, cache/, dated snapshots and .rebuild.lock stay ignored.

AGENTS.md: drop stale Relevant skills and Notes sections; graphify rule now says to always query the graph first.
