IronMonitor 7.0.13

Restore macOS GUI Overview CPU/RAM data by connecting the existing macOS readers to startup and background collection. Detected Apple GPU hardware remains visible when live telemetry is unavailable; failed readings stay unknown. imon status now includes the OS version, OS build, and hardware model alongside chip and GPU identity.

Live Apple GPU utilization, power, clocks, and temperature require an available telemetry source. This patch does not invent readings or elevate privileges. CPU percentages retain the existing macOS reader's average-since-boot semantics.

Close the GUI before upgrading:

cargo install ironmonitor --version 7.0.13 --locked --force
imon status
imon gui

Also fixes monochrome colors in the dark chat composer without changing its layout. Includes regression coverage for Apple inventory, unavailable accelerator rendering, status identity, and native macOS CPU/RAM collection and OS-version output.
