Subject: [PATCH 1/2] refactor(cli): update std.xxx.yyy() calls to module.yyy()
 format in tsc migrate

- Always apply post_process transforms in migrate_source even when deprecation_warnings is empty.
- Expand stdlib_rewrites in post_process to include all stdlib module prefixes.
- Add unit tests for std.xxx.yyy() migration.
