Address the documented sound-design and transition limits of the basic effects.
### Tasks and acceptance criteria
- [ ] Smooth or crossfade delay-time changes and define automation behavior without abrupt read-head jumps.
- [ ] Add tempo-synced delay divisions with deterministic tempo/seek behavior.
- [ ] Add true stereo processing and reverb diffusion/room controls rather than independent mono instances alone.
- [ ] Preserve old projects' effect identities, parameters and sound, or provide an explicit compatibility mode.
- [ ] Test stability at parameter extremes, stereo response, automation partitions and transition artifacts; document listening results.

### Implementation status
Planned. Delay time can click; reverb uses four damped mono combs without a room
model or stereo diffusion. Current decay is a feedback coefficient, not seconds.
Implemented as new Stereo Delay/Reverb identities, preserving original devices.
Delay uses fractional read-head crossfades and tempo divisions; reverb adds room
spacing and coupled stereo diffusion. Graph evaluation now processes coupled
channels together. Core, graph/direct DSP, partition, tempo, GUI persistence,
callback-guard and sanitizer tests pass. Listening previews/procedure are
documented; human listening is unverified. See BUILTIN_DEVICES.md.
