Skyler Lehmkuhl b301c63387 Address code-review findings across export, decode, and data model
Export correctness:
- Honor the user's color-range (Limited/Full) on the software encode path:
  thread full_range through gpu_yuv (new shader range uniform), the CPU
  swscale fallback (sws_setColorspaceDetails → BT.709 + range, fixing the
  BT.601 hue/level shift on odd-width exports), and the encoder color tags.
- Reject HDR + WebM up front with a clear message and log the forced HEVC
  override instead of producing an unplayable file.
- Delete dead render_frame_to_rgba_hdr (hardcoded Stretch; live HDR path
  already honors the fit mode).

Decode/playback (video.rs):
- Drain the decoder at EOF (send_eof + flush) so the final B-frame-delayed
  frames render instead of erroring; per-frame logic extracted to a helper.
- Missing-PTS frames continue monotonically rather than snapping to ts=0.
- Force exact thumbnail width so sub-128px sources aren't shown stretched.

Resource leaks (gpu-video-encoder):
- dmabuf import_raw: RAII guard frees the duped fd + partial VkImages/memory
  on every error path.
- vaapi alloc: free device/frames-ctx/AVFrames on the unexpected-DRM path.

Data model / robustness:
- collapse_boundary_spikes requires a full curve reversal (all control
  points) so it no longer deletes a real lens/sliver and drops the fill.
- Export audio spin-wait ignores a stale `finished` flag when a forward
  seek is pending (was rendering silence over real audio).
- RasterDiff apply_before/after take current dims and skip on a post-resize
  mismatch.
- beam_archive read_media_full caps the preallocation from untrusted total_len.

UI/visual:
- SVG export skips hidden layers/empty groups; import folds fill-opacity into
  gradients and surfaces failures as a notification.
- Active raster-layer border uses playback_time + overlay_transform.
- gpu_brush remove_layer_texture also evicts the stale low-res proxy.
- ensure_raster_resident_for_undo registers faulted frames in the LRU so
  resident RAM stays bounded.
