Description

Updates terser from ^5.17.4 (May 2023) to the current release, ^5.49.2.

I reviewed the changelog between the two versions against what the plugin actually uses: minify(), the result.code/result.map handling, the in-place nameCache mutation, and the options that cross the worker boundary through serialize-javascript. Nothing in the range breaks any of it and no plugin code changes were needed. All 19 existing tests pass unchanged against 5.49.2, including the exact-output, mangled-name, and error-message assertions, so no new tests are included.

The typescript devDependency moves from ^4.8.3 to the workspace catalog (^5.9.3, as alias already does) because terser's type declarations now pull in .d.cts files from its source-map dependency, and TS 4.8 can't parse those (TS2691), which broke test:ts.

Three terser defaults changed in this range, so users may see slightly different but equivalent output after upgrading:

• format.wrap_func_args is now false (v5.43.0): callbacks and IIFEs passed as call arguments are no longer wrapped in parentheses.
• undefined is now emitted as void 0 (v5.45.0): safer, since undefined can be shadowed.
• preserve_annotations (v5.26.0): enabling it now keeps /*#__PURE__*/-style annotation comments without also configuring the comments format option, and /*#__PURE__*/ is ignored when the side_effects compress option is off.

None of these affect the plugin's own behaviour or its test expectations.
