web_extract / browser_snapshot / delegate_task spill their full text under HERMES_HOME/cache,
which is mounted read-only into docker/modal (at /root/.hermes) and synced under ~/.hermes for
ssh/daytona/vercel — but the footer told the agent the HOST path, so read_file inside the
sandbox got 'File not found'. Translate through the existing
credential_files.to_agent_visible_cache_path (what tool_result_storage already does); local and
singularity are unchanged.
Salvaged from #72429 by @JonthanaHanh (the web_extract sites), widened to every footer.
