## What
Adds an explicit redirect from
`/docs/guides/monitoring-and-debugging.md` to
`/docs/guides/observability.md`.
## Why
The catch-all `/docs/guides/monitoring-and-debugging/:match*` rule
handles the bare path and subpages, but the root `.md` URL currently
ends up at `/docs/guides/observability/.md`, which 404s:
| URL | Before |
| --- | --- |
| `/docs/guides/monitoring-and-debugging.md` | 308 →
`/docs/guides/observability/.md` (404) |
| `/docs/guides/monitoring-and-debugging` | 308 →
`/docs/guides/observability/` ✓ |
| `/docs/guides/monitoring-and-debugging/logs.md` | 308 →
`/docs/guides/observability/logs.md` ✓ |
The new rule sits before the catch-all so it matches first, mirroring
the existing `observability/access-data.md` rule.
## Testing
- [ ] On the preview, `/docs/guides/monitoring-and-debugging.md`
redirects to `/docs/guides/observability.md` and returns 200
