fix: webhook platform support — skip home channel prompt, disable tool progress (salvage #4363) (#4660)

Cherry-picked from PR #4363 by @bennyhodl with follow-up fixes:

- Skip 'No home channel' prompt for webhook platform (webhooks deliver
  to configured targets, not a home channel)
- Disable tool progress for webhooks (no message editing support)
- Add webhook to PLATFORMS in tools_config.py and skills_config.py
- Add hermes-webhook toolset to toolsets.py + hermes-gateway includes
- Removed overly aggressive <50 char content filter that blocked
  legitimate short responses (tool progress already handled at source)
