RiskyMH bfb5399f25 feat(install): merge yarn v1 + berry into single file with full metadata ...

Merges Yarn v1 and Yarn Berry (v2+) migration into ONE yarn.zig file.

Changes:
- Auto-detects v1 vs Berry at runtime
- Shared workspace scanning and package.json parsing
- Full Berry metadata support:
  ✅ bin definitions (single/named/map formats)
  ✅ peerDependencies (added with .peer behavior)
  ✅ dependenciesMeta (optional markers)
  ✅ checksum conversion (Berry format → Bun integrity)

Deleted files:
- yarn_berry.zig (merged into yarn.zig)
- yarn_common.zig (merged into yarn.zig)

Missing from Berry (Bun will fetch from npm registry):
- scripts (not in lockfile)
- os/cpu constraints (not commonly in Berry lockfiles)
- man pages

Test status:
- v1 tests: ✅ passing
- Berry tests: need fixtures with proper YAML format
