AGENTS.md gets the "Syncing boards" section — what pushes, what pulls,
what a lost race looks like, and the two disciplines that make it safe:
local main advances only through the board and origin, and sync never
merges. The module map gains sync.py, the settings paragraph and the
Board view's description gain the sync chip and the author attribution,
and .env.example documents BOARD_SYNC / BOARD_SYNC_INTERVAL, including
the fetch-rate line for rate-limited remotes.
