Nicolò Boschi d7d137fa1e fix(daemon): drop the idle timeout that could kill an in-flight request (#3930)
* fix(daemon): drop the idle timeout that could kill an in-flight request

The daemon's idle checker measured idleness as "time since the last request
*started*" (IdleTimeoutMiddleware stamped last_activity on entry, never on
completion), so a retain, reflect or consolidation that outlived the configured
timeout was SIGTERM'd mid-flight — the client saw a connection error and the
work was lost. Raising the timeout only lowered the odds; 0 (the default
everywhere but the legacy cursor hook package) was the only safe value.

Rather than teach the middleware to count in-flight requests, remove the
feature: a shared local daemon that quietly exits under a long operation is not
worth the resource reclamation it buys. The daemon now runs until it is
stopped.

- Delete IdleTimeoutMiddleware, the idle-checker thread and DEFAULT_IDLE_TIMEOUT.
- Keep `--idle-timeout` parseable — hindsight-embed and every coding-agent
  integration still pass it — but ignore it, printing a note when it is
  non-zero. The integration packages therefore need no change and no release.
- Drop it from the current docs, the SDK/integration READMEs and the generated
  docs skill. The coding-agents README keeps the row marked deprecated because
  docs-freshness.test.ts requires every readable RawConfig field to be
  documented; versioned docs, blog posts and changelogs are left as history.

Closes #3903

* review: drop the now-dead logger and refresh the comments the removal invalidated

- daemon.py: the module logger only served the deleted idle checker.
- coding-agents daemon.ts / runtime.ts / runtime.test.ts and openclaw: comments,
  a debug line and the plugin-schema description still described an auto-exit
  that can no longer happen. The config fields stay (inert) as agreed.
