feat(pm): add --from pnpm migration for install command

Reads pnpm-workspace.yaml and converts to utoo config:
- workspaces/overrides → package.json
- catalog/catalogs → .utoo.toml (merged with existing config via
  PNPM_MIGRATE_KEYS whitelist)

Migration runs before init_registry so MERGED_CONFIG picks up the
generated .utoo.toml for catalog: protocol resolution.
