Subject: feat: add time-based effect activation with auto-passthrough

Effects now accept start/end time parameters and automatically passthrough
when inactive. Implements buffer chain integrity via compile-time validation.

- Effect base class: dispatch_render() checks time bounds, auto-passthroughs
  1:1 input/output effects outside [start, end] interval
- seq_compiler.py: validates producer/consumer lifespan constraints for
  multi-output effects, adds --validate flag, always validates before codegen
- Updated all 9 effect classes and test fixtures to pass start/end times
- check_all.sh: includes timeline validation step
- Tests: 34/34 passing, demo runs successfully
