Commit Message

fix: address Copilot review — hex validation and long-line cap

- parseHexRGB now validates each nibble explicitly; invalid hex chars
  return ok=false instead of silently parsing as black. matches the
  shiftLightness contract ("unparseable -> unchanged").
- changedTokenRanges caps line length at 500 bytes before running LCS
  to prevent O(m*n) memory blowup on pathological input (minified
  files, very long configs). lines above the cap still render with
  whole-line add/remove highlighting, just no word-level detail.

Copilot also flagged `for i := range n` as a compile error but that's
a false positive — Go 1.22+ supports integer ranges.
