feat(check): delegate linting to lint command for consistency

Aligns check.mjs with standard pattern across socket-* repos:
- check.mjs now delegates to `pnpm run lint` with appropriate flags
- Removes running biome directly
- Adds --all and --staged flag support
- Lint command is single source of truth for linting behavior
