Matches the Phase 1 design_system pattern the brief points at: own lint config, own tests, own coverage gate enforced in CI. The lint script was declared but unrunnable -- there was no eslint flat config, and the build tsconfig excludes tests (correctly; they must not ship in dist/), so type-aware linting had no project for them. Adds eslint.config.js and a lint-only tsconfig that widens the include without emitting. Running it surfaced one real defect: nth() interpolated a number into a template literal without String(), which the consumers' configs would have flagged. The gate also checks that the committed dist/ matches a fresh build. This is not theoretical -- the check caught the stale dist/ produced by that very String() fix on its first run. A stale dist/ in a tag ships old code to every consumer with no error anywhere, which is the one failure mode this packaging choice introduces. dist/ is excluded from the whitespace hooks: they would "fix" generated output that the next build immediately reverts. CI additionally re-runs the categorical ramp's constraint proof, so the palette cannot regress silently either.
