This CL migrates the `frontend_server_client` package into the Dart SDK repository. Key Changes: - Migration: Moved source code and tests into `pkg/frontend_server_client`. - Monorepo Compliance: Updated the pubspec to align with the SDK pub workspace setup. - Linting: Adopts `package:dart_flutter_team_lints` for analysis options and fixes associated linting errors. - Path Resolution: Resolved package configuration and script path issues encountered in local and CI environments; see the [Workspace Tests Fixes](https://docs.google.com/document/d/1UdiRqP19qYgj-ItxDfqXSdUU6CGimiyK3BmdvjtTEyw/edit?pli=1&tab=t.0#heading=h.xfm1ezicaoik) in the design doc for implementation details. Testing: - All tests passing locally. - CI try bots are green.
