Use firmware 1.2.3 display, connectivity, and platform capabilities

[sumitake]

Firmware 1.2.3 exposes useful display and connectivity capabilities that the host integrations did not use. This change enables them behind a cached local API-version check while retaining complete expiring redraws, the existing priority ladder, cloud/legacy text-and-shape fallback, and device-native Nyan playback.

• Add selective element cleanup, explicit layering, and small inline CI bitmap icons. Scoped clears handle priority reductions and type changes; no frame broker or background rendering service is introduced.
• Add separate local-token support, bounded USB/Wi-Fi fallback routes, and optional exact-device mDNS discovery using the firmware's actual HTTP service registration.
• Prevent uncertain audio/timer sends from being replayed across routes. Calendar chirps are attempted once per event edge, auto-busy requires a confirmed idle snapshot, and dry-run startup no longer clears the display.
• Add read-only diagnostic/discovery commands, a standard BMP screen export, asset subdirectory support, ordinary Home Assistant REST examples, and a finite on-device JavaScript example.

Validation: 433 tests passed; source distribution and wheel builds passed. Live firmware 1.2.3/API 27.5.0 checks confirmed pixel-level z-order, selective deletion and ownership, bitmap rendering, scoped cleanup, discovery over USB and Wi-Fi, Wi-Fi fallback readback, diagnostics/screen export, exact asset upload readback, and the finite JS demo's three polls, 30-second stop, and persisted counter. Home Assistant YAML/template qualification covered unknown state, JSON escaping and bounded TTLs. No timer/audio/authentication/network-settings changes were made for these probes.

Terra and Luna implemented bounded slices; Astra reviewed the combined changes and its actionable findings were closed. The first GitHub review batch was addressed together: explicit diagnostic host targeting and same-operation discovery recovery within the existing four-attempt budget. A fresh logical Gemini repository advisory returned PROCEED; native model identity was unavailable, so this is recorded as advisory evidence rather than independent model attestation. Full evidence and limitations are in the qualification report.

The current long-running host integrations have not been switched to this branch. The HA example is not installed into a running instance, and no token rotation or persistent JS autostart is included.
