LGTM: lockfile-only Dependabot bump

Only package-lock.json changes. @babel/plugin-transform-modules-systemjs goes from 7.23.9 to 7.29.8. It is a transitive dependency of @babel/preset-env, which asks for ^7.23.9 (package-lock.json:1913), and is not listed in package.json (package-lock.json:14-61). The bump also pulls in newer shared Babel internals (@babel/traverse, types, parser, generator, template, code-frame, helper-module-transforms, helper-module-imports, helper-plugin-utils, all at 7.29.x) and @jridgewell/*, and removes packages that only the old versions used.

What I checked in the lockfile:

• Nothing depends on a removed package. No remaining entry depends on @babel/highlight, @babel/helper-hoist-variables, to-fast-properties, @jridgewell/set-array, or the removed top-level chalk@2.4.2, ansi-styles@3, supports-color@5, has-flag@3, escape-string-regexp@1, color-convert@1 or color-name@1.1.3. Every remaining dependent asks for the newer major versions: chalk ^3/^4, ansi-styles ^4/^5/^6, escape-string-regexp ^2/^4.
• Every remaining user resolves to a nested copy. Each of them already has its own copy under its own node_modules/ (for example package-lock.json:2482, 6548, 6582, 12356, 13443), so the empty top-level slots break nothing.
• No duplicate Babel copies. The only nested @babel/* entry is preset-env's placeholder (package-lock.json:1952). The caret ranges held by @babel/core 7.24.0 (package-lock.json:199-207), @babel/helpers (631-633), @babel/preset-env (1913) and the plugins are all met by the single top-level 7.29.x versions.
• New dependencies are present. js-tokens (package-lock.json:10380), picocolors (package-lock.json:11327) and @babel/helper-globals (package-lock.json:436) are at top level.
• Node support is unchanged in practice. The @babel engines field stays >=6.9.0. jsesc 3.1.0 needs >=6, far below CI's node 20/22/24 matrix (.github/workflows/ci.yaml:20-28).

Runtime impact: probably none. babel.config.js:5 uses @babel/preset-env with its default modules setting, and SystemJS output only happens when you set modules: "systemjs". The newer shared Babel internals do run on every build and test, though. CI installs with npm ci (.github/workflows/ci.yaml:52-53) and then builds and runs the tests, so it is the real check that the mixed versions work together (@babel/core stays at 7.24.0 while its internals move to 7.29.x). I have not seen CI results for this PR and can't claim it passes.
