AI Modification Log: CI Config Mutation

Date: 2026-06-29

Change

• Updated X/Y/Z Run Diy Scripts steps so CI-only CONFIG_DEVEL and CONFIG_CCACHE settings are appended to openwrt/.config instead of $GITHUB_WORKSPACE/Configs/$CONFIG_FILE.
• Re-applied those CI-only settings after .config is regenerated before Firmware_Diy_Main.

Reason

The workflow previously mutated tracked config files during CI runs. Writing CI-only options to .config keeps repository configs clean while preserving the intended build-time ccache/devel settings.
