Adds vitest.base.node and vitest.base.jsdom with safety defaults
(clearMocks, restoreMocks, mockReset, unstubGlobals, sequence.shuffle)
and coverage thresholds (80/75/80/80). Migrates all feature configs
to the new base. Existing baseVitestConfig kept as backwards-compat
re-export of nodeVitestConfig.
Spec: §6.2
Aligns tooling packages with the core-* naming convention used by all
other foundation packages (core-shared, core-cms, core-api, core-trpc,
core-ui). Updates ~50 files: package.json names, devDependencies,
tsconfig extends, eslint.config imports, vitest.config imports, AGENTS.md
references, and the boundaries plugin patterns to match the new paths.
The tooling-specific patterns in boundaries/elements are now ordered BEFORE
the broader core-* pattern to ensure correct first-match-wins behavior.
