fix: make OPFS finalization and public cache repair failure-atomic
STO-RR-01. finalizePut re-acquired the origin mutation lease it was already holding. A Web Lock is not reentrant, so an ordinary PUT stopped for good at FINALIZE; it now calls the locked cleanup directly. A strict non-reentrant fake lease manager pins one acquire and one release per finalization. The adapter no longer reports a failed finalization as a plain write success either: the journal row stays COMMITTED for reconciliation, but the caller is told the write did not settle. STO-RR-02. A failure raised while serving a validated request now carries that request's kind. Defaulting every catch to CAPABILITIES made the client's own expected-kind check reject genuine quota, integrity and abort failures as protocol breaches and report them as UNSUPPORTED. Only an envelope the runtime could not read still answers at protocol level. STO-RR-03. The worker client decodes a response instead of adopting it: exact own-data descriptors, the negotiated protocol version, the exact awaited kind, a code inside the closed BrowserDataFailure set and a boolean retryable. An accessor, a proxy trap, an inherited or extra field and an unknown code all close the call as UNSUPPORTED rather than leaving it to time out. STO-RR-04. A marker read that fails transiently is unknown, not damaged, so it no longer deletes the candidate that may be serving traffic. Only a confirmed corrupt or missing marker enters the repair path. STO-RR-05. Staging never deletes a candidate it did not create. A repair replaces exact entries in place, so a failed fetch leaves every healthy asset and the active release usable; a candidate this call created is still removed on failure.
