refactor: rename eslint-config + typescript-config to core-eslint + core-typescript

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.
