chore(js): run npm pkg fix

[albert20260301]

Summary

• ran npm pkg fix at the repository root
• ran npm pkg fix --workspaces across all configured workspaces
• kept the diff scoped to package manifests only

Impact

This normalizes package metadata to npm's expected package.json shape. The published packages now use structured repository metadata. The private root package receives npm's empty version field normalization.

Validation

• npm pkg fix
• npm pkg fix --workspaces
• git diff --check
• bun run typecheck
• bun run build
• bun run lint
• bun run test

@francoischalifour could you review this when you have a slot? This is the requested npm pkg fix pass across the root package and all workspaces; CI/local gates are clean on my side.
