Move trampoline files (boot-hook, watcher, overlay) into trampoline/ subdirectory. Add upstream Luma v2.3.1 source at repo root with our additions: - Page::Ha (4th nav tab) with placeholder empty state - HA tab config schema and default entity mapping (ha-home/) - Nav keys renamed: "home" → "start", new "ha" tab between Apps and Settings - All state.rs/view.rs/main.rs/tests.rs updated for 4-tab navigation Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
