feat(bindings): Expand Node.js and Python bindings with full feature and effects API

Node.js native addon (sonare_wrap.cpp / sonare_wrap.h):
- Add effects: hpss, harmonic, percussive, timeStretch, pitchShift, normalize, trim
- Add spectrogram features: stft, stftDb, melSpectrogram, mfcc, chroma
- Add spectral features: spectralCentroid, spectralBandwidth, spectralRolloff,
  spectralFlatness, zeroCrossingRate, rmsEnergy
- Add pitch features: pitchYin, pitchPyin
- Add core utilities: hz/mel/midi/note conversions, framesToTime, timeToFrames, resample
- Add VecToFloat32 helper for efficient vector-to-typed-array transfer
- Promote all analysis methods onto the Audio class in index.ts
- Add structured result types (StftResult, MelSpectrogramResult, MfccResult,
  ChromaResult, HpssResult, PitchResult, StftDbResult) in types.ts
- Consolidate biome.json into root config; upgrade to Biome 2.4.8, TypeScript 6,
  Vitest 4; add yarn.lock and .gitignore

Python cffi bindings (libsonare/):
- Mirror new features in _ffi.py, analyzer.py, audio.py, and types.py
- Expand test_analyzer.py to cover new APIs

C API (sonare_c.h / sonare_c.cpp):
- Expose new feature and effects entry points used by both Node and Python bindings

WASM (wasm/bindings.cpp, js/index.ts):
- Expose matching feature functions via embind
- Add tests/wasm/features.test.ts with WASM feature coverage
- Expand tests/wasm/streaming.test.ts
