test: make multi-worker bob setup deterministic

[RerankerGuo]

Summary

• make test-06-multi-worker create Bob via hiclaw apply worker instead of a Manager DM request
• keep the rest of the test focused on multi-worker collaboration after Alice and Bob exist
• avoid CI flakes where the Manager is still processing heartbeat/task follow-ups or hits tool-guard approval before creating Bob

Why

Recent failures on #972, #983, #984, and older PRs all failed in test-06-multi-worker with the same pattern: the Manager did not produce a matching Bob creation reply, wait_worker_provisioned bob timed out, hiclaw get workers bob returned 404, and hiclaw-worker-bob did not exist. The logs also show the Manager processing unrelated heartbeat/task work or denied shell commands during the Bob creation window.

This makes Bob creation an unreliable LLM interaction inside a test whose stated purpose is multi-worker collaboration. test-02-create-worker already covers Manager-mediated worker creation for Alice; test-06 can use deterministic setup for Bob.

Verification

• bash -n tests/test-06-multi-worker.sh
• git diff --check

I could not run the embedded integration test locally because this environment cannot access /var/run/docker.sock (permission denied).

@shiyiyue1102 Hi! This PR makes the multi-worker test-06-multi-worker.sh bob setup deterministic by replacing the LLM-driven DM instruction with a direct hiclaw apply worker --name bob ... call. This bypasses the SHARD_A flake that has been blocking PRs #972, #973, #975, #976, #983, #984 (all hit "Manager never invoked hiclaw create worker --name bob" — confirmed by inspecting #984's downloaded artifacts where the hiclaw-worker-bob session directory did not exist at all).

Just rebased onto current main and CI is 18/18 green (verified just now). If you can land this first, the next CI runs on the six Tier-3 PRs above should turn green automatically — they all hit the same root cause this PR fixes. Branch is MERGEABLE. Could you prioritize this one?
