* chore(workspace): extend base configs and remove duplicate tooling Make tsconfig, eslint, and vitest configs extend workspace base instead of duplicating settings. Remove per-repo prettier and commitlint configs in favor of root-level configs. Use catalog: for typescript-eslint dep. * fix(workspace): restore commitlint config for standalone repo hooks Sub-repos need their own commitlint config since each has its own .git and husky hooks. Removed redundant scope-empty rule. * fix: restore standalone configs for CI compatibility Base config extension doesn't work in CI where repos are cloned independently. Restore self-contained configs. The only remaining change from this PR is the commitlint cleanup.
