feat(T06): hostPath working-memory sync and repo-relative sink paths

Mount the-custodian memory/working from the railiance01 clone (hostPath)
so sweep writeback commits daily-triage notes; worker runs as uid 1000;
progress events store repo-relative working_memory_path; ops inventory
defaults use custodian:// URIs.
