## Summary
- Adds a reusable `<LegalDocVersions />` component (dropdown below the
page header) that swaps the active legal doc version inline via shallow
query-param routing (`?version=v1`).
- Converts `/terms` and `/enterprise-terms` from MDX to TSX pages and
moves their content into versioned MDX under
`apps/www/data/legal/<doc>/v1.mdx`.
- Seeds `v2.mdx` for both docs as a copy of v1 with the effective date
bumped to 6 May 2026 — the actual v2 language edits from legal will land
in a follow-up commit.
## Behavior
- `/terms` and `/enterprise-terms` default to v2 (latest); search
engines and bare URLs always see the latest.
- `/terms?version=v1` (and equivalent for enterprise) renders v1.
- Selecting a version updates the URL via `router.replace({ shallow:
true })` — no full page reload, browser back/forward works.
- Selecting the latest version clears the `version` query param.
- Existing `/docs/company/terms → /terms` redirect still works.
`noindex/nofollow` preserved on `/enterprise-terms` (both via meta and
the existing header rule).
## Out of scope
- The 5 v2 provision edits per agreement (lands in a follow-up once
Legal hands over the final language).
- `/privacy` and other legal pages — those keep their current pattern.

## Test plan
- [ ] Visit `/terms` — defaults to v2, dropdown shows "Version 2 — May
6, 2026" and "Version 1 — July 11, 2025"
- [ ] Visit `/terms?version=v1` — renders v1
- [ ] Select v1 from the dropdown — URL becomes `?version=v1`, content
swaps without full page reload (no document request in Network tab)
- [ ] Select v2 — URL drops the `version` param, latest renders
- [ ] Browser back/forward steps through prior selections
- [ ] Repeat the above on `/enterprise-terms`
- [ ] Confirm `/enterprise-terms` is still `noindex, nofollow`
