Replace Prettier with Biome for formatting JS/TS/JSX/CSS/JSON. The CI
format check drops from ~23s to ~0.4s.
- Unify config into a single root biome.json (formatter + linter); the
former apps/readest-app/biome.json was linter-only
- Mirror the old .prettierrc.json style: 100 line width, 2-space indent,
LF, single quotes, trailing commas
- Enable the CSS tailwindDirectives parser for @apply in globals.css
- Convert // prettier-ignore comments to // biome-ignore format:
- Root scripts and lint-staged now run biome; apps/readest-app lint runs
`biome lint` (lint-only) so formatting stays a separate CI step
- Drop prettier + prettier-plugin-tailwindcss dependencies
Markdown/YAML are no longer format-checked (Biome does not format them)
and Tailwind class sorting is no longer enforced.
