grammY getUpdates returns "Request to getUpdates timed out after 500 seconds"
but RECOVERABLE_MESSAGE_SNIPPETS only had "timeout". Since
"timed out".includes("timeout") === false, the error was not classified as
recoverable, causing the polling loop to exit permanently.
Add "timed out" to RECOVERABLE_MESSAGE_SNIPPETS so the polling loop retries
instead of dying silently.

* fix(telegram): handle Grammy HttpError network failures (#3815)
Grammy wraps fetch errors in an .error property (not .cause). Added .error
traversal to collectErrorCandidates in network-errors.ts.
Registered scoped unhandled rejection handler in monitorTelegramProvider
to catch network errors that escape the polling loop (e.g., from setMyCommands
during bot setup). Handler is unregistered when the provider stops.
* fix(telegram): address review feedback for Grammy HttpError handling
- Gate .error traversal on HttpError name to avoid widening search graph
- Use runtime logger instead of console.warn for consistency
- Add isGrammyHttpError check to scope unhandled rejection handler
- Consolidate isNetworkRelatedError into isRecoverableTelegramNetworkError
- Add 'timeout' to recoverable message snippets for full coverage
