fix(manager): add safe worker deletion wrapper

[RerankerGuo]

Summary

• add a worker-management delete wrapper that calls hiclaw delete worker <name> with the valid positional CLI syntax
• return structured JSON so the Manager only reports deletion after command success
• add a records-only cleanup path for state.json, worker-lifecycle.json, and workers-registry.json to avoid malformed write_file cleanup loops
• update Worker management guidance and lifecycle reference to use the wrapper

Fixes #967.

Verification

• bash -n manager/agent/skills/worker-management/scripts/delete-worker.sh manager/tests/test-delete-worker-script.sh
• git diff --check
• bash manager/tests/test-delete-worker-script.sh (skips in this host because jq is not installed; Manager images install jq, and the test runs full assertions when jq exists)

@shiyiyue1102 Hi! This PR addresses #967. Just rebased onto current main (was conflicting) — CI is now green (18/18). Adds a safe hiclaw delete worker <name> wrapper that cleans state.json / worker-lifecycle.json / workers-registry.json so Manager stops looping on bad delete commands. Could you take a look when convenient?
