fix(manager): stop repeated diagnostic loops

[RerankerGuo]

Summary

• add Manager prompt safeguards against repeating the same no-op or malformed troubleshooting command
• define Worker deletion completion as the target disappearing from hiclaw get workers
• update worker lifecycle guidance to avoid looping on Matrix room probes such as copaw channels list after deletion

Fixes #974.

Tests

• git diff --check
• rg -n "Diagnostic loop safeguard|Worker deletion is complete|Delete Completion Boundary|Stop repeated diagnostics" manager/agent/AGENTS.md manager/agent/copaw-manager-agent/AGENTS.md manager/agent/skills/worker-management/references/lifecycle.md manager/agent/skills/worker-management/SKILL.md

@shiyiyue1102 Hi! Both SHARD_A copaw/copaw and copaw/hermes failed. Same pattern as #984 — in the copaw/hermes case the hiclaw-worker-bob session directory does not exist at all and Manager never invoked hiclaw create worker --name bob — Manager only created alice. The copaw/copaw failure is similar (bob got created but a downstream assertion failed). The failure mode is a test-prompt interpretation flake, not anything in this PR's Manager prompt + worker-management guidance changes.

This PR is docs-only + prompt guidance; it doesn't touch runtime code paths. Could you re-run CI or merge if you agree the flake is unrelated?
