@copilot finialize the work: fix build make tests passing

Build and tests are now all passing. Here's a summary of what was fixed:

• Build: Added @types/node and vitest as devDependencies to @ts-dev-tools/react (needed for TypeScript compilation with pnpm's strict isolation)
• Snapshots: Updated all test snapshots to reflect pnpm-based behavior:
  • Git hooks now use pnpm run instead of npm run (since test projects have pnpm-lock.yaml)
  • SymlinkDependenciesService now symlinks individual packages (pnpm has per-package node_modules)
  • test:ci script uses pnpm run test:cov in unit tests (pnpm projects), npm run test:cov in e2e tests (npm projects)
  • Added jsdom peer dependency resolution line to core e2e snapshots
  • Updated biome schema (preset: "recommended" for migration spec, recommended: true for e2e)
  • Updated duplicate dependency lists to include vitest (now exposed via pnpm)
• Tests: Filtered npm warn allow-scripts warnings from stderr assertions (npm 11 behavior)

All 127 tests pass (core: 120, react: 7).
