## Summary
- **Fix `callWithTimeout` timer leak**: the `setTimeout` was never
cleared when the callback resolved first, leaving orphaned timers (up to
15 minutes) in the Node.js event loop. Now uses `try/finally` with
`clearTimeout`.
- **Properly classify timeout errors**: introduced
`ExecutionTimedOutError` so the Lambda driver can throw
`LOGIC_FUNCTION_EXECUTION_TIMEOUT` instead of
`LOGIC_FUNCTION_EXECUTION_FAILED` — users now see "Function execution
timed out" instead of the generic "Function execution failed."
## Test plan
- [x] Execute a logic function normally and verify it still works
- [x] Trigger a logic function timeout and verify the error message says
"Function execution timed out" (not "Function execution failed")
- [x] Verify that a deleted logic function invocation logs a specific
"was deleted" warning
- [x] Verify no orphaned timers remain after logic function execution
completes
