fix(audio): correct OLA synthesis and extract shared ola_encode/ola_decode
- Remove erroneous Hann synthesis window from synth.cc (g_hann * tmp[j]).
Hann analysis at 50% overlap satisfies w[n]+w[n+H]=1, so rectangular
synthesis gives perfect reconstruction; applying Hann twice was wrong.
- Extract ola_encode()/ola_decode()/ola_num_frames() into src/audio/ola.h+cc.
spectool and test_wav_roundtrip now use the shared functions.
synth.cc lazy-decode path stays inlined (see TODO for future refactor).
- Drop dead <atomic> include and g_hann array from synth.cc.
- Drop dead window.h include from spectool.cc.
- Update PROJECT_CONTEXT.md, COMPLETED.md, TODO.md to reflect correct
analysis-only Hann window and new ola.h API.
handoff(Gemini): OLA synthesis bug fixed + ola.h factorized. synth.cc
lazy-decode still inline (TODO item added). 34/35 tests pass; WavDumpBackendTest
failure is pre-existing and unrelated.
