Stage 1: project foundation (strict TS, lint boundaries B-1..B-7, directory structure, CI, boundary tests)

- dedicated git repo at /home/avi/Projects/Lumen (main)
- TypeScript strict (target ES2022, bundler, exactOptionalPropertyTypes, noUncheckedIndexedAccess)
- ESLint 9 + typescript-eslint strictTypeChecked + eslint-plugin-boundaries for B-1..B-7, no-restricted-globals/syntax for B-1/B-7
- Prettier 3.5
- Structure per IMPLEMENTATION-CONTRACT.md §4 (src/platform/idb|cache|sw, storage, data, sync/{transport,verifier}, domain/{emergency,schedule,map,festival,readiness,clock,favorites}, ui/{components,views,router,render}, app, emergency-baseline, assets, public, content, pipeline, tests, scripts)
- CI: .github/workflows/ci.yml (typecheck + lint + format + test)
- Boundary tests: tests/unit/boundaries.test.ts (4 tests) + scripts/check-boundaries.ts
- No feature code, no PWA/IDB/sync/mesh/accounts per contract Stage 1
