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).

 **Last release tagged:** v0.6.0 — rolled up Phase 2B, v0.5.1 Streams A/B/C, 1C-γ, Plan B refactor (Cycles 1+2), management-surfaces revamp, and the doc-structure redesign into one tag.

+Three parallel worktree streams under PM coordination (relay-bus), completing the restructure begun with Phases 1/2/5:
+
+- **Phase 3 — setup wizard SW migration + step registry** (Dev-A, merge `9df2fee`). `create_vault` / `attach_vault` SW handlers own the full vault-creation/attach flow (embed/unlock, encrypt+push, register_device+addDevice, persist config+image, `session.setCurrent`; failure path locks+frees the handle). `setup.ts` collapses 1230→58 LOC (UI-only shell, no `relicario-wasm` import); step registry + state + `clearWizardState` + `finishSetup` extracted to new `setup/setup-steps.ts`. `clearWizardState` bound to `beforeunload` + `goto('mode')`. Copy-vault-JSON escape hatch preserved.
+- **Phase 4 — vault.ts split + vault_locked lift** (Dev-B, merge `3b8368d`). `vault.ts` 1037→194 LOC. Five named modules (`vault-shell`, `vault-sidebar`, `vault-list`, `vault-drawer`, `vault-form-wrapper`) plus two support modules (`vault-context` — the VaultController contract; `vault-router` — hash routing + pane dispatch, to hold vault.ts ≤250). `vault_locked` RPC intercept lifted into `shared/state.ts`'s `sendMessage` wrapper. 80ms debounced sidebar search (`SEARCH_DEBOUNCE_MS`); `ensureDrawerClosedForRoute`; `#vault-status-slot` footer staged for Phase 6.
+- **Phase 6 — get_vault_status + sidebar status indicator** (Dev-C, merge `397cc78`). `get_vault_status` SW handler returns cached `{ahead, behind, lastSyncAt, pendingItems}` with no network call; `vault-status.ts` renders the sidebar-footer indicator (`renderStatusIndicator` into `#vault-status-slot`, refreshed on mount + manual `↻` button, no timer polling). Closes the last `relicario status` CLI/extension parity gap. Also nulls `state.gitHost` on the explicit `lock` handler (symmetric with session-expiry) so the indicator can't show a stale `lastSyncAt`.
+
+Final merged-tree validation: **423/423 vitest** (62 files), `build:all` clean (only the pre-existing 4MB WASM size warning). Task 7.1 done-criteria sweep: all green.

 - **CLI restructure** (`2026-05-04-cli-restructure-design.md`) — *already shipped* as Plan B Cycles 1+2 (`b9bd152`, `3dd1e1b`, `3759f6a`, `e69b347`); the last gap (read-side `refresh_groups_cache` callers in list/get) closed in `d717f0d`. Done-criteria all met.
 - **Security polish** (`2026-05-04-security-polish-design.md`) — *already shipped* as Stream A Cycle 1 (`89090a8`) plus follow-ups (`0c9387f` start.sh fourth window, `229e483` recovery_qr.rs docs). All four phases done.
-- **Extension restructure** (`2026-05-04-extension-restructure-design.md`, plan `docs/superpowers/plans/2026-05-30-extension-restructure.md`) — half-shipped:
-  - ✅ **Phase 1 (StateHost typing)** — merged `c3f8e35` (4 commits, 378/378 tests). View+PopupState moved to `shared/popup-state.ts`; `StateHost` interface fully typed; `__resetHostForTests` exported; double-registration guard. PopupState widened to absorb VaultState's vault-tab-only fields.
-  - ✅ **Phase 2 (SW storage extract)** — merged `b6707f4` (1 commit, 376/376 tests). `loadDeviceSettings` / `saveDeviceSettings` / `loadBlacklist` / `saveBlacklist` consolidated in `service-worker/storage.ts`; `itemToManifestEntry` moved to `service-worker/vault.ts`. Router files shrank ~70 LOC combined.
-  - ✅ **Phase 5 (P2 cluster)** — merged `0496dfe` (5 commits, 377/377 tests). Inactivity timer rule inverted (READ_ONLY_CONTENT_CALLABLE exclusion set); `state.gitHost` cleared on session expiry; `teardownSettingsCommon` extracted; `Promise.allSettled` in devices (trash.ts was a no-op — single-message load path on current main); MutationObserver `scan()` debounced 200ms.
-  - ⏳ **Phase 3 (Setup wizard SW migration + step registry)** — Effort: L. Depends on Phase 1 ✅. Biggest single phase. Adds `create_vault` / `attach_vault` SW handlers; setup.ts drops direct WASM imports + collapses six renderStepN/attachStepN pairs into a step registry + adds `clearWizardState`.
-  - ⏳ **Phase 4 (vault.ts split + vault_locked channel lift)** — Effort: M. Depends on Phase 1 ✅. Splits 1037-LOC vault.ts into 5 modules (vault-shell, vault-sidebar, vault-list, vault-drawer, vault-form-wrapper); lifts the vault_locked RPC intercept into shared/state.ts's sendMessage wrapper.
-  - ⏳ **Phase 6 (get_vault_status + sidebar status indicator)** — Effort: S-M. Depends on Phase 4. Closes the `relicario status` CLI/extension parity gap.
-  - Combined test count at end of three-stream merge: **389/389** vitest passing (baseline 371 + 18 new across the three phases).
+- **Extension restructure** (`2026-05-04-extension-restructure-design.md`, plan `docs/superpowers/plans/2026-05-30-extension-restructure.md`) — ✅ **COMPLETE** (all six phases merged; see the dated landing section above).

 Beyond extension restructure, ROADMAP medium-term holds Phase 4 command palette (no spec yet). Long-term: relay server, mobile.
