refactor: Bump @babel/core from 7.12.3 to 7.29.7 - #992

Closes #982

Upgrades @babel/core (devDependency, pinned) from 7.12.3 to 7.29.7. This replaces the Dependabot PR with a lock file regenerated on the current gh-pages.

This resolves Dependabot alert GHSA-4x5r-pxfx-6jf8 (low: arbitrary file read via a sourceMappingURL comment, @babel/core <= 7.29.0, fixed in 7.29.6 by babel/babel#18001). @babel/core is a development-only dependency, so this does not trigger a release.

Lock file

The lock file was regenerated on the current gh-pages with npm install @babel/core@7.29.7 --save-exact. The bot's lock file predates #990 and #991 and would have reverted browserslist (4.29.4 → 4.28.1) and fast-uri (3.1.9 → 3.1.2), as well as caniuse-lite, electron-to-chromium, node-releases, update-browserslist-db and baseline-browser-mapping. Here the diff is limited to @babel/core and its own dependencies, and lockfileVersion stays at 2.

Build check

The repository has no CI build, so the bundle was compared locally:

• npm ci --ignore-scripts followed by npm run webpack (production mode) was run on gh-pages and on this branch, and both builds compile.
• The resulting bundle.js is byte-identical (sha256 0f4418eea4b11335be13d8c5bee0ad6d691a28e0145e8bc34798000d2a462a33), and so is bundle.js.LICENSE.txt.
• Running Babel on _app/main.js, _app/UI.js and _app/echo.js with the webpack config's preset (@babel/preset-env, babel-loader caller flags) gives the same output under 7.12.3 and 7.29.7. The sources only use template literals and const/let, so no Babel helpers are injected.

This PR therefore does not need a rebuilt assets/js/bundle.js. One unrelated observation: the committed assets/js/bundle.js on gh-pages already differs from a fresh build of gh-pages itself, and this PR does not touch it.

@babel/preset-env stays at 7.12.1

• The effective Babel config is only the babel-loader options in webpack.config.js (presets: ['@babel/preset-env'], no targets). The repo has no .babelrc, babel.config.* or browserslist config. babel-preset-es2015 and babel-preset-react are not referenced anywhere.
• @babel/preset-env 7.12.1 declares the peer dependency @babel/core ^7.0.0-0, which 7.29.7 satisfies. A newer Babel 7 core runs older plugins and presets.
• The upgrade moves packages that @babel/preset-env shares with @babel/core (@babel/compat-data, @babel/helper-compilation-targets and @babel/helper-validator-option, each from 7.12.1 to 7.29.7) within the caret ranges @babel/preset-env 7.12.1 declares.
  • @babel/preset-env 7.12.1 ignores plugin names in @babel/compat-data that it does not know.
  • @babel/compat-data 7.29.7 still contains all 40 plugin entries that @babel/preset-env 7.12.1 uses, so no transform is dropped.
  • The identical build output confirms this.
• Upgrading @babel/preset-env itself is a separate change and is not needed for this fix.

Changes

Release notes from babel/babel releases, v7.12.4 to v7.29.11. The list only covers packages whose installed version changes in this PR, each within its own version range, for example @babel/core and @babel/helpers from 7.12.x but @babel/parser only from 7.29.3. Features, fixes, spec compliance, performance, output optimization, polish and revert entries are listed individually. Internal and documentation entries are grouped as counts. Versions with no entries for these packages are omitted.

Relevance for this repository: the 7.29.6 source map fixes contain the security fix, and the build uses no source maps. Helper changes (e.g. babel/babel#12115, babel/babel#15182, babel/babel#18287) only apply when helpers are injected, which is not the case here. The 7.25.9 entry babel/babel#16907 (support for the BROWSERSLIST / BROWSERSLIST_CONFIG environment variables) restores support that later 7.x versions had lost. The installed @babel/helper-compilation-targets 7.12.1 already honored these variables when no targets are configured, so the net effect from 7.12.1 to 7.29.7 is no change.
