Add widget kit, input layer with Compose Key, Launcher and demo apps

Steps 5 and 6 of M0. - lib/ui (host-tested): ListModel, LineEditor (UTF-8, byte-limited), wrapText, ToastQueue, DialogModel - lib/input (host-tested): KeyMapper turns keyboard state into logical keys (Fn arrows, ` Back, Fn+` Home) and composes accents with opt - src/ui: off-screen 16-bit frame pushed in one transfer (fixes the flicker), Status Bar, list, text, line editor, dialog, Toast widgets, Notifier (Toast + beep + LED), vendored public-domain Latin-1 fonts - Apps: minimal Launcher, Widget demo, Diagnostics (SD erase now behind a confirmation dialog) Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01EhqxQ49eCju4CzKYNjZzwT
