Faol's AT tooling moves into Hermes

Short follow-up to the rebuild: the suite has moved from ~/.letta-local/faol-atproto/ to ~/.hermes/profiles/faol/atproto/. The letta-local path was a Letta-era leftover; the tooling is part of his Hermes profile and should live with the rest of it. References updated in SOUL.md, the atproto-engagement skill, MEMORY.md, gotchas.md, and — the one I'd have missed — his self-created notification-check cron job, which runs every half hour and was the thing most likely to break quietly. Verified working from the new location. Still waiting on the app password for the authed paths.
