chore: bootstrap inkling project (Task 1)

Adds package.json, tsconfig.json, tsconfig.node.json,
electron.vite.config.ts, vitest.config.ts, .gitignore, and
package-lock.json. Verified Node 24.15.0 + npm 11.12.1 via Volta.
better-sqlite3 12.9.0 native build succeeded against VS 2022 +
Python 3.12.

Plan v0.4 had two install pin issues; adjusted live and logged
in plan Task 1 Step 2:
- electron-vite@2.3.0 + vite@6.0.3 ERESOLVE (peer ^4||^5).
  Promoted build-tool chain: electron-vite 5.0.0, vite 7.3.2,
  @vitejs/plugin-react 5.1.4 (vite@7 is the compatible overlap;
  vitest@4.1.5 also accepts vite@7).
- @types/uuid@11.0.0 deprecated stub (uuid@11 ships own types);
  removed from devDependencies.

Other deps installed at the planned exact pins. Step 8 sanity:
TypeScript 6.0.3, Vitest 4.1.5, Electron 41.3.0 (npm ls).
