Capture is now item + track only (master removed as a scope; still bypassed
as out-of-scope chain). Realtime records the selected track's own output via
per-track post-fader sends into a hidden temp track, fixing the silent file.
Timer-driven realtime capture behind ICaptureBackend (begin/tick/abort via
OnTimer, non-blocking). Records master into a hidden temp track, moved to the
bank non-destructively with idempotent restore across every terminal path.
Pure phase machine unit-tested. Track/item deferred; realtime is non-deterministic.
Replace the four capture modes with item/track/master scope actions. Each infers
its range (razor-else-time) and enforces FX scope via non-destructive
FX-bypass-around-render (RAII I_FXEN snapshot/restore over ancestors + master).
Corrects the defect of items captured through parent FX.
Four wet capture actions route to OfflineRenderBackend (snapshot/restore
RENDER_*, 32-bit float), produce a Sample, add to the bank, persist. Pure
render_settings maps source mode to RENDER_SETTINGS and parses P_RAZOREDITS
(tested). No arrange insertion. True dry deferred to M10.
RENDER_FORMAT now uses the base64 float-WAV config (raw bytes were rejected
into a 16-bit/44.1 fallback); RENDER_SRATE pinned to the project rate.
Unsaved projects prompt Save then refuse if cancelled — no default-location
fallback. Harden deriveBankPaths against empty projectDir.
ICaptureBackend/CaptureRequest seam + OfflineRenderBackend driving snapshotted
RENDER_* with dither/normalize forced off for bit-identical output, RenderFailed
via filesystem check, and a pure capture_paths lib with tests. Spike action registered.
