Switch to pnpm, add Biome for linting and formatting

- Replaced npm with pnpm across package.json scripts and CI workflows
- Added @biomejs/biome with project-specific config (space indent, single
  quotes, no semicolons, parameter decorators enabled for NestJS)
- Auto-fixed all formatting and lint issues across 24 source files
- Updated CI to use pnpm/action-setup, release workflow uses pnpm
- Added lint and lint:fix scripts, separated typecheck from lint
- Removed package-lock.json, added pnpm-lock.yaml
