Brandon Thomas 6708ff55b4 Never crash: SVG path data no longer loops forever on a number after Z
Path data like "M0 0 L10 0 Z9" repeated Z implicitly for the stray number; Z consumes no
numbers, so the parser looped forever appending close-paths until memory ran out (a 1-byte
change to a valid SVG used 24 GB and was killed). A number after Z is a syntax error, so
parsing now stops there and keeps what was read, as the spec asks. Also denies the panic lints
in the crate (it had no panic sites).

Brandon Thomas 94e1c86d89 IO-2/SHP-5/PRV-2: PSD import, SVG import + vector/text conversions, persistent disk cache
- effectcraft-psd (L1): PSD/PSB reader from Adobe's published file format spec (layers, groups,
  masks, blend modes, text engine data, lfx2 effects, fill/adjustment layers, vector masks;
  1/8/16/32-bit, RGB/CMYK/Gray/Lab/Indexed, raw/RLE/ZIP) and a minimal writer for fixtures.
- File > Import: importAs footage|composition|compositionLayerSizes, layer (Choose Layer);
  groups -> precomps (pass-through collapses), text -> editable text, styles -> Layer Styles,
  adjustments -> adjustment layers with effects; UI asks the Import Kind for Photoshop files.
- effectcraft-svg (L2): SVG parser (shapes, paths, transforms, use, CSS, gradients) and
  rasteriser; .svg imports as footage, continuously rasterised when the switch is on.
- layer.create: shapesFromVector, shapesFromText, masksFromText, editableText (stub removed).
- Disk cache (render::disk_cache): LZ4 content-keyed frames and layer buffers, LRU size limit
  from prefs, atomic writes, restart persistence; edit.purge clears it, cache.diskStats query;
  viewer frames read/write it and the timeline shows disk-only frames in blue.
