Subject: [PATCH 1/2] Implement fix flag for tsc lint

Updates `cli/src/commands/migrate.rs` to expose `migrate_source` publicly.
Updates `cli/src/commands/lint.rs` to consume `migrate_source` when the `--fix` flag is true, conditionally modifying file content to remove deprecations before linting is finalized.
