Initial commit: add FTerm app

Add complete initial codebase and assets for FTerm. Includes Electron main/preload, services (PTY, AI, GitHub OAuth, secure store, remote terminal), renderer React app (src/), plugins API, widgets, CI and release GitHub workflows, configuration (ESLint, TypeScript, Vite, Tailwind), README, CHANGELOG, LICENSE, .gitignore, example .env, package.json and lockfile, and all documentation and media assets. This provides the baseline for building, testing, and releasing the first public version of the app.
