Consolidates six open PRs into one reviewable change, rebased onto main with their commits kept, plus review fixes. The capo, fast-chord-run, effective-tuning and event changes mirror patches I've been playing with a real guitar in a patched build.

Closes #24, closes #73, closes #75, closes #77, closes #79, closes #81.
Supersedes #72, #74, #76, #78, #80, #82.

What changes

• Capo charts (Capo charts: every fretted note is expected capo semitones sharp #73): fretted notes are read from the nut, the Rocksmith way (capo-4 E chord = A7 D6 G0 B5); only fret 0 sounds at the capo. Fixed for expected pitch, the desktop engine's chart and scoreChord (capo 0, open notes moved to the capo fret), and the detected-fret display fallback.
• Fast chord runs (Fast runs of the same chord shape score random EARLY misses #75): a ringing chord in a fast run no longer scores as an EARLY miss. The engine stamps the chord with the member closest to the chart time, a stamp within one poll of the window edge counts as on time, and one early strummed frame no longer locks a scoreChord chord as a miss.
• Effective tuning (Does not detect correctly for songs converted to E standard #24): expected pitches follow core's effective getTuning() / getCapo() / getCentOffset() (chart-transform providers) and resync within a tick when a provider restages mid-song.
• Technique flags (Every note is scored as a slide, and bends are never detected (technique flags misread) #79): bend/slide are read off the wire format (sl/slu -1 = no slide, bn = bend amount). Before, every plain note looked like a slide.
• Section stats on desktop (Desktop engine path records no per-section stats (session.sections is always empty) #81): per-section stats are tracked on the engine-verifier path, and each judgment is binned by its note's section.
• Richer events (notedetect:hit/miss should carry per-string chord verdicts, techniques, latency and section for stats plugins #77): notedetect:hit/miss gain key, per-string strings, techniques, latencyMs, avOffsetMs, detector, section, counted, points, multiplier, streak, isDefault, plus verdictAt / noteEnd. All fields are additive. verdictAt / noteEnd let a renderer still flash a hit whose verdict landed after its gem was culled (sustained notes on the engine path); the highway_3d side of that will be a separate PR.

Review fixes on top

• The tuning resync now runs at the top of the desktop bridge tick, so a mid-song retune is also picked up on addons without the engine verifier (matchNotes(null) fallback).
• Offsets are rounded to whole semitones for the Int32 engine, and setChart's pitchCheckCents is widened by that rounding error (up to 50 c), so a +45 c record no longer pushes notes out of tolerance. The scoreChord window is unchanged.
• One shared bend/slide reader and one section helper across the merged changes; engine chord members keep sus.

Tests

node --test test/*.test.js: 386/386 pass. Includes every test from the six PRs, plus new tests for the downlevel-path resync, the rounding gate and verdictAt / noteEnd.

Version 1.33.0; CHANGELOG entry added.

📝 Walkthrough

Version 1.33.0 updates pitch mapping for capo and host-transformed tuning, bend and slide detection, chord timing, and section statistics. Hit and miss events gain per-string verdicts and additional judgment context. Tests, documentation, and package metadata are also updated.

Changes: Note detection scoring and judgment events

Layer / File(s)	Summary
Capo and effective tuning screen.js, test/_loader.js, test/capo_expected_pitch.test.js, test/effective_tuning.test.js, test/verify-target-context.test.js, README.md	Pitch mapping and desktop chart payloads account for capo, effective tuning, and cent offsets. Tests cover capo conversion, tuning changes, and verifier context.
Wire-format technique flags screen.js, test/_loader.js, test/technique_flags.test.js	Bend and slide detection accepts boolean and numeric chart values across scoring and engine payloads. Tests cover flag interpretation and scoring.
Chord timing and section statistics screen.js, test/fast_chord_runs.test.js, test/engine_section_stats.test.js	Chord verdicts use the detected member closest to the chord time and clamp qualifying early timestamps. Section counts use the judged note’s chart section.
Judgment details and release documentation screen.js, test/judgment_events.test.js, CHANGELOG.md, CLAUDE.md, README.md, package.json, plugin.json	Hit and miss events include additional note, technique, timing, detector, section, scoring, and per-string fields. Tests and documentation cover the payload additions. Version metadata changes to 1.33.0.

The test should require a scoring request after retuning so it catches a future fallback regression. This is a bounded test gap, not an established production failure.

Assert the post-retune scoring request.

The existing chord remains scorable after the retune, and the fallback path calls scoreChord. The conditional assertion can skip the offset check if that request stops occurring. Assert the request unconditionally. Advancing to a different chord is not required.

Suggested test fix

-    if (h.scoreChordReqs.length > before) {
-        const req = h.scoreChordReqs[h.scoreChordReqs.length - 1];
-        assert.equal(Array.from(req.offsets).join(','), '-2,-2,-2,-2,-2,-2',
-            'a chord scored after the restage uses the new tuning');
-    }
+    assert.ok(h.scoreChordReqs.length > before,
+        'the fallback path scored a chord after the restage');
+    const req = h.scoreChordReqs[h.scoreChordReqs.length - 1];
+    assert.equal(Array.from(req.offsets).join(','), '-2,-2,-2,-2,-2,-2',
+        'a chord scored after the restage uses the new tuning');
