fix: chat-assent chicken-and-egg + agent stops after errors

Three fixes for the session where the agent proposed a plan, waited
for 'proceed', then re-queued instead of being auto-approved:

1. Chat-assent fallback: when the operator says 'proceed' but the
   preceding turn had NO pending approvals (agent proposed plan in text
   without calling request_execution), inject a system note telling the
   agent to execute the plan now. Opens the assent window so subsequent
   config_mutation commands auto-run.

2. SOUL.md: instruct agent to ALWAYS call request_execution/run when
   proposing a plan, not wait for 'proceed' first. This ensures a
   pending approval exists for chat-assent to grant.

3. SOUL.md: stronger Docker instructions — Debian 13's docker.io package
   installs the daemon but NOT the docker CLI binary. Must use
   get.docker.com in post_install. Added 'handling errors' section:
   diagnose, try alternatives, continue — don't stop after one failure.
