Light the full Creator Micro surface

[edwin-zvs]

Summary

• support AG06–AG12 as lighting-capable equivalents of the existing pane and response controls while retaining legacy ACT06–ACT12 input compatibility
• drive all 13 switch LEDs: dynamic session state, pane availability/focus, and stable Yes/No/Enter colors
• preview aggregate fleet state on underglow without persisting or rewriting the device keymap
• document the required all-Agent layer and revised lighting contract

Verification

• cargo test -p construct-cli --bin construct creator_micro (11 passed)
• cargo build
• git diff --check

No TUI recording: the user-visible change is exclusively on external hardware and cannot be demonstrated in a deterministic terminal capture.
