fix(status): surface global health from unattached contexts

[chubes4]

Fixes #11910

Unregistered homeboy status responses now include a structured control_plane section that explicitly says its health is not_checked and provides the bounded local follow-up command: homeboy status --global. This preserves the default fast path and avoids remote probes while making runner/control-plane health discoverable.

Tests cover the unregistered response contract and a disconnected configured runner reported through the bounded global status path.

Verification

• cargo fmt --check
• cargo test -p homeboy-cli default_status_from_unregistered_cwd_returns_actionable_context_without_global_scan --lib
• cargo test -p homeboy-cli global_status_from_an_unregistered_cwd_is_local_and_bounded --lib
• git diff --check
• cargo clippy -p homeboy-cli --lib -- -D warnings remains blocked by three pre-existing homeboy-core warnings in http_api.rs and notify_outbox.rs; this change introduces no clippy findings.

AI assistance

OpenAI gpt-5.6-sol via OpenCode inspected the status contract, implemented the structured global-health discovery, and added deterministic coverage. Chris Huber remains responsible for every line.
