Fix tools path resolution and add tests

- Use _resolve_repository_path() for explore, terminal and code commands
  so tools no longer rely on a 'directory' key in the repository dict.
- Fall back to repositories_base_dir/repositories_dir via get_repo_dir()
  when no explicit path-like key is present.
- Make VS Code workspace creation more robust (safe default for
  directories.workspaces and UTF-8 when writing JSON).
- Add unit tests for handle_tools_command (explore, terminal, code) under
  tests/unit/pkgmgr/cli/commands/test_tools.py.
- Add E2E/integration-style tests for the tools subcommands' --help
  output under tests/e2e/test_tools_help.py, treating SystemExit(0) as
  success.

This change fixes the KeyError: 'directory' when running 'pkgmgr code'
and verifies the behavior via unit and integration tests.
