v1.1.3

• Fix a slot leak: the onAccepted observer callback ran after acquire but outside the try/finally that guarantees release(), so a throwing observer (unreachable metrics backend, a TypeError in the closure) left the slot occupied — until lease expiry on Redis/APCu, and permanently with InMemoryBulkheadStore (which ignores the lease). The callback now runs inside the try.
• Document the release-path failure semantics: a release() exception masks the callback's exception (reachable via getPrevious(), which PHP chains automatically) and loses a successful result — a store exception from call() means "outcome unknown", never "did not happen". Pinned by tests.
• Docs: fix the name-pattern anchor shown in README.md/README.ru.md/llms.txt to the \z the code actually uses ($ matches before a trailing newline); document that keyPrefix is trusted configuration (not validated, unlike name) and the token trust model (CSPRNG tokens protect against accidents, not adversaries — the trust boundary is Redis access itself).
