fix: update compose submodule — use native s6 multi-profile supervision

Updates the compose submodule to commit 3f82c9d on branch
fix/hermes-entrypoint-simple, which drops all custom entrypoint
scripts and uses the image's native s6-overlay profile supervision.

The five profiles (ashley, claire, finn, matt, paul) auto-start
on boot via the s6 reconciler reading their gateway_state.json.
