feat(achievements): local engine + tabbed Profile shell (epic PR1) (#587)

Adds the Achievements & Feats of Power local engine, fully offline.

Core (static/v3/profile.js): the Profile screen becomes tabbed exactly
like v3 Settings (.fb-tabbar/.fb-tab/.fb-tabpanel, active tab persisted in
localStorage 'v3-profile-tab'). A Profile (main) tab carries the existing
cards + a Feats trophy-shelf mount (#v3-profile-feats-slot, earned-only),
and an Achievements tab carries a plugin mount
(#v3-profile-achievements-mount) + empty-state note. A new
`v3:profile-rendered` event fires after every render so the plugin
re-injects (mirrors v3:settings-rendered).

New bundled plugin (plugins/achievements/): SQLite engine
(unlocks/counters/comp_ledger/sync_queue) with pure threshold/criterion
math in the testable sibling engine.py (P-V); routes activity/
report-unlock/report-criterion/catalog/earned/feats/remove-me. Feats read
activity counters only (batched song:ended POST; notes only when notedetect
present — graceful degradation); competency Achievements evaluate from
progression events only — the integration law, never crossed. Catalogue is
always shown (locked=greyed), grouped by the real progression paths
(Global/Guitar/Bass/Drums/Keys, auto-extending) with per-category earned
badges. Versioned window.feedBack.achievements registration API with the
__feedBackAchievementsPending load-order queue + achievements:ready event.

Verified natively (uvicorn) end-to-end + Playwright (tabbar, earned-only
Feats shelf, greyed catalogue, registration API, zero console errors);
24 plugin tests pass incl. the integration-law assertion.

Opt-in/privacy/data-min gate (PR2) and the hosted wall (PR3) follow.
