Nightly bot: major version bump, needs review

Package: @babel/core 7.29.7 → 8.0.5 (devDependency in apps/desktop/package.json; pnpm-lock.yaml re-resolves the hoisted @babel/core to 8.0.5, so apps/mobile picks it up too)

CI: ❌ Desktop Checks and Mobile Checks fail. Every Jest suite fails before any test runs:

Starting from Babel 8.0.0, the 'loadPartialConfig' function expects a callback. If you need to call it synchronously, please use 'loadPartialConfigSync'.

Lint & Typecheck, Unit & Integration (web), E2E, Scripts and SonarCloud pass. They don't go through Babel.

Breaking changes relevant to this codebase

• Sync config APIs now need a callback, or the *Sync variant (loadPartialConfig, transform, and others). babel-jest@29.7.0 calls loadPartialConfig synchronously, so Jest can't run in either app.
  • Affected: apps/desktop/jest.config.* and every desktop test; apps/mobile tests (they use the hoisted @babel/core)
• Babel 7 plugins and presets have Babel 7 peer ranges. The lockfile now pairs Babel 8 with packages that only support Babel 7:
  • babel-jest@29.7.0: peer @babel/core ^7.8.0
  • @babel/plugin-proposal-decorators@7.29.7: peer ^7.0.0-0. Used in apps/desktop/babel.config.js and apps/mobile/babel.config.js for WatermelonDB legacy: true decorators
  • babel-preset-expo@55.0.25 (mobile) and @react-native/babel-preset@0.86.3 / Metro (desktop and mobile) are built and tested against Babel 7
• Desktop fossil build (ADR-0027). The macOS app builds only from the primary checkout's frozen node_modules, which has Babel 7. Merging this would leave package.json and the lockfile out of step with that fossil. react-native-macos@0.81's Metro/Babel toolchain was never validated on Babel 8.

Breaking changes NOT relevant

• preset-env useBuiltIns removal: we don't use @babel/preset-env directly
• babel-node / @babel/register fixes: not used
• Parser/generator spec fixes (html entities, bigint prefixes, new import access): no effect on app code
• isTSX removed from plugin-syntax-typescript types: we don't use it directly
• semver → verkit internal refactor: internal only

Peer dependency impacts

Babel 8 support would need a coordinated upgrade, not a single bump:

• babel-jest → a Jest 30+ line with Babel 8 support (and jest / jest-expo / @react-native/jest-preset to match)
• @babel/plugin-proposal-decorators → 8.x
• babel-preset-expo and @react-native/babel-preset / Metro → versions that officially support Babel 8 (upstream Expo / RN releases)
• @babel/runtime is already ^8.0.0 in desktop; not a blocker

Recommendation: Unsafe, don't merge

This bump breaks every mobile and desktop test run. The Babel toolchain (Expo, React Native/Metro, babel-jest) doesn't support Babel 8 yet, and desktop is also bound by the fossil build. Close this PR (@dependabot ignore this major version) and come back to Babel 8 when Expo and React Native ship Babel 8 support. Upgrade it with those packages, not alone.
