test: use the installed OpenCode entrypoint

The Linux routing test still referenced the obsolete bin/opencode name. With intentional path-only Runtime selection, that stale fixture was no longer masked by automatic discovery; use the locked opencode-ai 1.18.9 bin/opencode.exe entrypoint on every platform.

Keep the approved 0.12.0 notes and bilingual feature matrices explicit that local OpenCode paths are not prevalidated and fail only at actual launch.
