create $HOME/.cache/gh before delegation, ensuring the WRITABLE_HOME_DIRS entry
exists even when absent. Add a regression test covering wrapping when that

Create $HOME/.cache/gh before calling flare_sandbox::wrap.
Supervisor::spawn and run_headless_in call agentflare_jobs::sandbox::wrap without creating this directory. flare_sandbox::wrap skips an absent writable home directory. If $HOME/.cache/gh is absent, a wrapped gh cache write can therefore target the read-only home and fail with EROFS. Create the directory in the shared wrapper before delegating, and add a regression test for the absent-directory case.
