docs(settings): third-review contracts across READMEs, catalogs, and the write-path integrity note

The seam README states the JSON-shaped write boundary, watch-disposer
quiescence, async listener containment, and the drained teardown; the
provider README rewrites Behavior around the operation chain,
read-modify-write, writer lock, ready reconcile, and leaf-level YAML
diffs, and updates Known Limitations to the residual guarantees.
A new Agent Note records the round's decisions and supersedes the
original note's deferred-lockfile alternative (cross-linked in place).
Chinese counterparts updated pair-by-pair (three briefed minimal
updates, one whole-document translation); type-equiv, config, cordis,
and module-graph catalogs re-recorded.
