chore: configure build tooling and dependencies

Set up the foundational build configuration for Mission Control:

Frontend Build (Vite + TypeScript):
- package.json: React 19, TanStack Query, Zustand, Framer Motion
- tsconfig.json: Strict TypeScript with path aliases (@/)
- vite.config.ts: Tailored for Tauri (port 1420, ignores src-tauri)

Styling (Tailwind CSS):
- tailwind.config.ts: Custom surface color palette (zinc-900/800/700)
- postcss.config.js: Tailwind + autoprefixer pipeline
- tailwind.config.js: Generated config (superseded by .ts)

Code Quality:
- eslint.config.js: ESLint 9 flat config with TypeScript + React hooks
- .gitignore: Exclude node_modules, dist, coverage, test artifacts

This establishes the monorepo structure where:
- Frontend lives in src/ and builds to dist/
- Tauri backend lives in src-tauri/ with its own Cargo workspace
