S00-031: Record newly available external input for independent verification

Changes: Release external waiting state for S00-031 through tasks.py. Input: New verified root cause and supported host execution context supplied in state/handoffs/S00-031.md. Actual host /tmp/codex-daemon-1000 uid1000/mode0700 is valid; outer sandbox deliberately masks it read-only mode000. Installed-version primary source confirms this design; TMPDIR/no-daemon cannot fix nested guard. Approved OUTER HOST EXECUTION of bounded no-model inner codex workspace-write probe passes project write/read/remove and denies outside write EROFS30, no outside file created. No socket mutation or broader roots. Fresh executor/QA must read handoff, request approved outer host execution and independently repeat, document and review; no task acceptance claimed.
Validation: External input availability checked; tasks.py release-external succeeded. Acceptance and dependent tasks remain unverified pending fresh executor and independent review.
