devv-eve 977dc6479d fix(daemon): prevent task stall when agent process hangs on stdout (#947)
When an agent CLI process hangs (e.g. a tool call blocks on unreachable
I/O), the daemon's scanner blocks indefinitely on stdout, preventing the
Result from ever being sent. This causes tasks to stay in "running"
state permanently with no further events.

Three-layer fix:

1. Agent backends (claude, opencode, openclaw, gemini): add a watchdog
   goroutine that closes the stdout/stderr pipe when the context is
   cancelled, forcing the scanner to unblock. Also set cmd.WaitDelay
   so Go force-closes pipes after 10s if the process doesn't exit.

2. daemon executeAndDrain: add an independent drain timeout (backend
   timeout + 30s buffer) with context-aware select on both the message
   channel and the result channel, so the daemon never blocks forever.

3. daemon ping path: add context-aware select so pings don't deadlock
   if the agent backend stalls.

Closes #925
