release: v0.7.0 — extension restructure complete (Plan C Phases 3/4/6)

Completes the extension restructure begun in v0.6.0. Phases 3 (setup
wizard SW migration + step registry), 4 (vault.ts split + vault_locked
lift), and 6 (get_vault_status + sidebar status indicator) all merged to
main (9df2fee, 3b8368d, 397cc78) via three parallel worktree streams.

This commit is the release-prep wrap-up:
- Version bump to v0.7.0 across the three relicario crates + Cargo.lock,
  extension/package.json, and both extension manifests (the manifests had
  lagged at 0.5.0 — corrected here).
- CHANGELOG.md v0.7.0 entry.
- STATUS.md: extension restructure moved to shipped; Phases 3/4/6 landing
  section added.
- ROADMAP.md: v0.7.0 row added; Up-next now command palette.
- extension/ARCHITECTURE.md: all three phases integrated (new vault-*
  modules, setup-steps.ts, get_vault_status protocol + status indicator,
  vault_locked lift, git-host sync cache).
- Plan completion checkboxes ticked.

Task 7.1 verification: done-criteria sweep all green; 423/423 vitest;
build:all clean (only the pre-existing 4MB WASM size warning).
