Pinned Zig linker unavailable

The Linux linker lane requires Zig 0.17.0 for the fixed x86_64-linux-gnu.2.31 target. Doctor or ara-zigcc could not locate or confirm that version; linking cannot proceed.

#Common causes

• ARA_ZIG is missing or points to an invalid executable, or the detected Zig version differs from 0.17.0.

#Fixes

• Install Zig 0.17.0 and set $env:ARA_ZIG='<path to zig 0.17.0>/zig.exe' in PowerShell.

• Run ara-export doctor --platform linux; ara-zigcc itself requires ARA_ZIG even when doctor finds Zig on PATH.
