refactor: restructure to standard Go project layout (cmd/ + internal/)
- Move entry point to cmd/streamdeck-lets-go/ - Split package main into internal packages: - internal/deck: hardware control (Deck, events, brightness) - internal/render: key rendering, icons, fonts, PageManager - internal/web: HTTP API + embedded SPA - internal/daemon: event loop, autoswitch, screensaver, actions - Add ConfigDir() to internal/config - Export cross-package API (Deck, PageManager, WebServer, etc.) - Move dist/arch/ → packaging/ with updated PKGBUILD/.SRCINFO - Add Makefile (build, test, vet, fmt, install) - Update README with new build commands and project structure - Delete unused media.go stub
