Reset core/viewer/editor/mcp packages and apps/editor from private-editor

Wholesale swap of packages/{core,viewer,editor,mcp} and apps/editor with the
versions from the private editor repo, which is the production source of truth.

Setup changes:
- packages/{core,viewer,editor} versions held at 0.7.0 baseline (matching
  the most recent published release) so a bump=minor publishes 0.8.0
- packages/mcp held at 0.1.1 (never published; first publish will go through
  the new release.yml flow)
- peerDependencies and devDependencies for inter-package @pascal-app/*
  references pinned to ^0.7.0 instead of '*' / 'workspace:*' so they are
  valid for npm consumers
- Root package.json: TypeScript bumped to 6.0.2, added overrides for
  @types/react, @types/react-dom, @types/three to prevent JSX namespace
  fragmentation across the workspace
- release.yml extended to also publish editor and mcp; 'both' option renamed
  to 'all'; added a sync step that updates inter-package peerDeps/devDeps to
  match the new versions on every bump (so viewer/editor/mcp tarballs always
  reference the version of core they were built against)
- Root scripts gained release:editor and release:mcp shortcuts

Verification:
- bun install --frozen-lockfile is consistent
- packages/{core,viewer,mcp} build cleanly, dist/index.d.ts emitted
- packages/editor check-types reports 21 pre-existing errors, identical to
  what private-editor currently reports

Open PRs against editor-v2 will need rebasing/conflict resolution.
