feat(core): host per-instrument workingTuning capability + read-API/event (working-tuning PR 1) (#658)
* feat(core): host per-instrument workingTuning capability + read-API/event (working-tuning PR 1)

Introduce window.feedBack.workingTuning — the live, host-authoritative current
instrument tuning (offsets + string-count + reference pitch + assumed/verified
provenance), distinct from any one song's tuning and from a soft opt-in default.
It's the single source of truth the highway, library, and plugins (tuner,
Virtuoso, minigames) will read so a retune or instrument swap is reflected
app-wide instead of being re-derived per surface.

PER-INSTRUMENT: state is a map keyed by `${instrument}-${stringCount}` (e.g.
guitar-6 / bass-4, the selector's key) — your guitar's tuning and your bass's are
kept separately; get() returns the selected instrument's, and switching the
selector surfaces that instrument's own remembered tuning. You only ever deal
with the one you've picked.

Modeled on the shipped `tuning` capability + the `feedBack.theme` read-API:
synchronous get(instrument?), set(state,{provenance,instrument}) mutator,
setCurrentInstrument(), resetToDefault(), and a `working-tuning-changed` event
that fires on change and once on hydration (carrying which instrument changed).
In-memory, seeded from /api/settings, reset-on-restart. Registered as a separate
`working-tuning` exclusive-owner capability (tuner = sole writer, others read).

Foundation only — pure plumbing, nothing writes to it yet and no behavior
changes. The tuner becomes the writer (and the gate's E->C# asymmetry is fixed)
in a later PR.

Frontend-only: new static/capabilities/working-tuning.js, loaded from
static/index.html + static/v3/index.html. Per-instrument state machine verified
by a stubbed node harness (separate guitar/bass slots, selector switch, isolated
writes, verified stamp, reset, defensive copies, capability registration).

* fix(working-tuning): resolve review P1/P2s + add behavioral test harness

Addresses the manual + Codex review of PR 1 (working-tuning foundation).

P1 — named tunings were dropped by the boot seed: /api/settings.tuning may be a
name ("Drop D") OR an offsets list, but the seed only handled the list and stored
offsets:null for names. The seed now resolves a name to per-string semitone offsets
via /api/tunings (ratio vs Standard; reference pitch cancels).

P1 — async seed could clobber state a consumer had already written: _seedFromSettings
resolves after boot and used to overwrite _currentKey/_byInstrument unconditionally.
It now bails when state was already _touched (and re-checks after the /api/tunings
leg), so an explicit set()/setCurrentInstrument()/resetToDefault() before hydration
wins. Hydration still fires.

P1/P2 — shallow copy leaked live nested arrays: get() and set() now clone offsets and
verifiedStrings on both ingress and egress, honouring the "readers can't mutate live
state" contract.

P2 — provenance/verification state machine made coherent by construction:
verified <=> verifiedStrings is an array AND verifiedAt is a finite number. A tuning
change invalidates prior verification unless a fresh bundle is supplied; a "verified"
claim with no strings or a null/absent timestamp is repaired (assumed / stamped now).

P2 — bare-instrument writes targeted a hard-coded default string count: _keyOfResolved()
resolves an omitted string count against the current selection (same instrument), so
set({instrument:'bass'}) / set({stringCount:5}) hit the selected bass-5, not bass-4.

Test — adds tests/js/working_tuning.test.js (the harness the PR described but did not
commit): 11 behavioral cases over a stubbed window — registration, per-instrument
isolation + selector switch, defensive copies, the verification invariant, bare-key
routing, named + offsets-list seeding, and the boot-race guard. Full tests/js suite:
no new failures (the 12 pre-existing branch failures are unrelated).
