Release Codex Deck v0.6.2

[dazer1234]

What changed

• adds explicit per-host READY, DEGRADED, CONNECT, and OFFLINE health states
• preserves last-known agent placement while marking uncertain or offline host tiles
• emits authenticated degraded relay health and detects stale snapshots by local receipt time
• routes reasoning controls through the current native Micro encoder HID events
• discovers the current official standalone keycap command runner while retaining the older fallback
• restores snapshot-only relay client compatibility

Why

Undocumented Codex desktop internals changed after an app update, and a connected relay could previously leave last-known state looking live. The release makes uncertainty visible and updates command routing to match the currently loaded Codex Micro bridge.

Validation

• TypeScript check passed
• 76/76 automated tests passed
• Elgato validation passed for the build and exact packaged plugin
• exact Windows and macOS release archives passed their self-tests and dry runs
• all three extracted artifacts passed the private-state/protected-SVG audit
• live Windows-to-Mac relay testing passed snapshots, native actions, joystick, reasoning, encoder, and agent routing
• plugin v0.6.2.0 loaded on the real 15-key Stream Deck MK.2 without restarting either Codex app
