rename(#162): scrub remaining hm1nd references from comments and MCP instructions

All functional renames (MANAGER_NAME, MANAGER_AGENT → "root") were done in
earlier commits. This cleans up the stale `hm1nd` strings that remained in
doc comments, test fixture labels, and the manager MCP server instructions
(which told the manager its config lived at /agents/hm1nd/config/agent.nix).
