Provide sample-based sounds beyond the current oscillator presets.
### Tasks and acceptance criteria
- [ ] Define supported sample formats, mapping, looping, envelopes, voice limits and memory budgets.
- [ ] Load/prepare samples outside callbacks and expose an instrument editor with undo.
- [ ] Persist sample references and mappings with missing-media reporting and relinking.
- [ ] Provide original or appropriately licensed example sounds and document their licenses.
- [ ] Test playback rate conversion, boundaries, voice release, missing assets and project reload.

### Implementation status
Planned. Phase 38 supplies no sample instrument or sample library.
Implemented: a 32-voice, single-root WAV sampler with whole-file looping,
envelopes, gain, cached linear rate conversion and an undoable editor/relink
workflow. Format 15 persists relocatable sample references and reads v1–v14.
Missing/invalid media becomes reported silence. Original licensed example and
core, GUI, persistence, release/loop and allocation/callback tests are included.
See BUILTIN_DEVICES.md for memory/format and transposition limits.
