docs(mentorship): add programme sunset callout to all pages (#32)

## Summary

The open Mentorship Programme is being closed. This PR adds a `:::caution[Programme Sunset]` aside to the top of every page under `src/content/docs/mentorship/` (and the nested `resources/` subdirectory) so anyone landing on these pages immediately understands the current state of the programme.

The callout:

- States that the open programme has been sunset and is no longer accepting new participants
- Notes that the pages remain available as reference material
- Describes the new private, invite-only personalised development programme
- Clarifies that there is no application process
- Directs interested readers to the Discord community as the route to being noticed for an invite

## Files changed

- 11 main mentorship pages (`00-faq` through `10-graduation`)
- 10 resource pages under `mentorship/resources/`
- 21 files total, 168 insertions, 0 deletions

## Test plan

- [x] `pnpm lint` passes (0 cspell issues across 176 files)
- [x] `pnpm build` succeeds (177 pages built, no Starlight aside errors)
- [x] Spot-checked rendered placement on `00-faq.md` and `resources/career-prep.md`
- [ ] Visual confirmation in deployed preview

## Notes

While working on this, I noticed one pre-existing em-dash in `mentorship/07-writing-code.md` (line 184, in the body content, not the callout). Out of scope for this PR but worth a future cleanup pass to bring those legacy docs in line with your tone guide.
