SCSS formatting and keyframe parsing land

Biome updates SCSS formatting for parentheses and variables, and teaches keyframe parsing/lints about SCSS variable declarations.

SCSS parenthesized values stay inline when scalar (denbezrukov8fa36d9)

The CSS formatter now keeps simple SCSS parenthesized scalars inline, while still expanding nested lists/maps and preserving the right trailing-comma behavior for nested map cases. This reduces over-breaking in common SCSS patterns like include arguments and map values.

SCSS variable declarations get smarter formatting and comment placement (denbezrukov4636e85)

Variable-declaration formatting was broadened to handle semicolonless declarations, line comments in values, and comments on the :/value boundary more accurately. The change also touches several SCSS layout helpers, so variable-heavy stylesheets should format more predictably.

SCSS keyframes now accept variable declarations (denbezrukovdad900e)

The parser and syntax tree were extended so SCSS variable declarations can appear inside @keyframes, with formatter support and generated node updates to match. Lints for duplicate selectors and !important in keyframes were adjusted to skip over these SCSS-specific declarations instead of bailing out early.

Other misc changes

  • Markdown paragraph node cleanup: removed the unused hard_line slot and updated parser/formatter/generated factories accordingly (jfmcdowell605e45e)
  • Markdown fuzz corpus expanded to cover loose lists with mixed space-tab sublists (jfmcdowellb9d47c7)
  • Dependency bumps: pnpm, Rust 1.96.0, GitHub Actions, and @types/node (741dc89, 9669424, 5c016d5, 39a9637)
