docs: surface MR-766 publisher OCC in storage / errors / constants
- storage.md: document the row-level CAS annotation on `__manifest.object_id`
  and the `expected_table_versions` OCC contract on `ManifestBatchPublisher::publish`.
- errors.md: list `ManifestConflictDetails` and its variants alongside `ManifestError`.
- constants.md: add `PUBLISHER_RETRY_BUDGET = 5`.

Per AGENTS.md "Maintenance contract": new schema construct, new constant, and
new typed error shape all need to ship with the source change.
