v1.5.0

• README requirements now match composer.json (rasuvaeff/context ^0.1, psr/http-message ^2.0); README.ru.md gains the missing cooperative-context section (#36).
• Http\RetryingHttpClient accepts a context: (rasuvaeff/context): checked before every attempt and between 50 ms sleep slices, so cancellation or an expired deadline interrupts a long backoff or Retry-After wait; its ContextException is never retried and deliberately escapes PSR-18. A final response (not retryable, or from the last attempt) is always returned; with a retry pending, the ended context throws instead (#31).
• onRetry/onExhausted hooks are now best-effort in Retry and RetryingHttpClient: a throwing hook no longer aborts the loop or replaces the operation's exception. Hook exceptions go to the new Retry::onHookError() / onHookError: callbacks; a ContextException from a hook still propagates. Behaviour change: code that threw from a hook to stop retrying must use stopIf() / the retry predicates instead (#33).
• RetryingHttpClient gains retryAfterJitter: — an opt-in JitterInterface that spreads a Retry-After delay upwards only (never earlier than the server asks), still capped by maxRetryAfterMs (#34).
• RetryingHttpClient gains idempotentOnly: (default false): a request with a non-idempotent method passes through with a single call. New RetryDecisions::isIdempotent(). The README and llms.txt now warn that the defaults retry POST/PATCH (#35).
