Replaced blocking `subprocess.run` calls with `asyncio.create_subprocess_exec` to ensure the Telegram bot event loop remains responsive during long-running deployment tasks.
Key changes:
- Switched to `asyncio.create_subprocess_exec` for command execution.
- implemented `asyncio.wait_for` to handle the 300s timeout.
- Added explicit process cleanup (kill/wait) on timeout.
- Manually decoded stdout/stderr since async subprocesses return bytes.
Verified with a reproduction script showing the event loop gap dropped from ~2.0s (blocking) to ~0.1s (non-blocking).
