CapRust 0.9.8 - captions, beat-sync and new presets

CapRust 0.9.8

Added

• SRT sidecar export. New switch in the export dialog plus File
  menu entry writes .srt next to the video (or standalone) from
  normalized caption cues. Shared CueWindow utilities in core.
• Beat-sync (analysis + markers). Onset-flux BPM detection runs
  as a background job from the Sound panel, grids persist per media
  with size/mtime fingerprinting, stale grids prune on load, and
  markers draw on the ruler. Snap-to-beat stays a follow-up.
• 4 effects, 7 transitions, 4 voice FX. Negative, pixelate,
  sketch, sharpen; dissolve, smooth ×4, circle-close, pixelize
  (xfade path, overlap handling included); telephone, bass, echo,
  chipmunk per-clip voice filters. Docs: CONTRIBUTING +
  TRANSLATING guides.

Fixed

• Edit menu Split/Delete/Ripple Delete were stubs since PR 7;
  they now dispatch the same undoable commands as the keys.
• Caption rows no longer stack on overlaps. Whisper segments
  overlap in time but enable windows clamped only within a segment;
  a normalization pass clamps across segments (preview and export
  share the plan, one fix covers both).
