feat: only post Slack 'Working on it!' on first thread mention (#1250)
* feat: only post Slack 'Working on it!' on first thread mention

* feat: randomize Slack trace reply phrase

Pick from a small list of friendly phrases instead of always saying
'Working on it!' so the bot feels less robotic. Explicit messages (e.g.
'Taking a look...' from PR review path) are unaffected.

* adjust phrases
