# Problem
Currently, task timeouts are handled using SIGALRM within the task process
itself. This approach is bad because:
- SIGALRM can be blocked by other signals
- Tasks can exceed their configured timeout without being terminated
# Solution
This PR moves timeout enforcement from the task process to the supervisor:
- Task process sends SetTaskExecutionTimeout message to supervisor before
execution
- Supervisor monitors task execution time using monotonic clock
- Supervisor terminates task with SIGTERM when timeout is reached
# Changes
- Added SetTaskExecutionTimeout message to IPC protocol
- Added timeout tracking and checking in supervisor
- Modified task runner to send timeout to supervisor
