fix(plugin-metro): support Windows dynamic imports

[jbroma]

Summary

• Convert resolved Metro dependency paths to file URLs before passing them to dynamic import
• Fix Windows absolute paths like C:... being treated as unsupported ESM specifiers
• Add a patch changeset for @rock-js/plugin-metro

Verification

• pnpm --filter @rock-js/plugin-metro... build
• pnpm exec prettier --check .changeset/warm-windows-imports.md packages/plugin-metro/src/lib/getReactNativeDeps.ts packages/plugin-metro/src/lib/start/loadMetroConfig.ts
• pnpm exec eslint packages/plugin-metro/src/lib/getReactNativeDeps.ts packages/plugin-metro/src/lib/start/loadMetroConfig.ts

Downstream validation: verified the equivalent patch in module-federation/core with the Metro Android host running on Windows: host, remote, and nested remote rendered successfully in the emulator.
