feat: profile-aware routes, provider sync, channel settings improvements

- Add hermes-profile.ts for dynamic profile path resolution (all backend
  routes now read from active profile directory instead of hardcoded ~/.hermes/)
- Add profile switcher dropdown in sidebar, reload page on switch
- Sync PROVIDER_PRESETS with Hermes CLI (fix keys: kimi-coding→kimi-for-coding,
  kilocode→kilo, ai-gateway→vercel, opencode-zen→opencode; remove moonshot)
- Sync PROVIDER_ENV_MAP with Hermes models.dev + overlays (correct env var names)
- Add gateway restart after adding model provider
- Don't write GLM_BASE_URL/KIMI_BASE_URL for zai/kimi (let Hermes auto-detect)
- Write API keys to .env and credential_pool for all providers
- Built-in providers skip custom_providers in config.yaml
- Add debounce + per-field loading state for channel settings inputs
- Run hermes setup --reset for profiles without config.yaml
- Create empty .env for new profiles (not copied from default)
