## Description
`headroom install status` crashes with an `AttributeError` when the
probed health endpoint returns a non-dict `config`.
```python
if payload and isinstance(payload, dict):
click.echo(f"Health URL: {manifest.health_url.replace('/readyz', '/health')}")
click.echo(f"Backend: {payload.get('config', {}).get('backend', manifest.backend)}")
```
`payload` is guarded as a dict, but `payload['config']` is not.
`dict.get('config', {})` only substitutes the `{}` default when the key
is **absent** — a present-but-non-dict `config` (`null`, a string, a
list) is returned as-is, and the chained `.get('backend', ...)` then
raises `AttributeError`, crashing the command with a raw traceback.
Reachability: the Headroom proxy normally returns `config` as an object,
so this bites when `install status` probes a port that a different or
older service is occupying (which can emit `config: null` or a
non-object), or a build that emits `config: null`. The correctly-guarded
sibling already exists in the codebase — `wrap.py`'s
`_proxy_health_config` does `config = payload.get("config"); return
config if isinstance(config, dict) else None`.
## Fix
Guard the `config` value with `isinstance(config, dict)` before the
`.get('backend', ...)` lookup, mirroring `_proxy_health_config`. A
non-dict (or missing) `config` falls back to the manifest's backend.

## Type of Change
- [x] Bug fix (non-breaking change that fixes an issue)
- [ ] New feature (non-breaking change that adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality to change)
- [ ] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)
## Changes Made
- `headroom/cli/install.py`: `install status` guards `config` with
`isinstance(config, dict)` before reading `backend`.
- `tests/test_cli/test_install_cli.py`: add
`test_install_status_survives_non_dict_config` (health payload with
`config: null` must not crash; backend falls back to the manifest).
- `CHANGELOG.md`: Bug Fixes entry.
## Testing
- [ ] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`)
- [ ] Type checking passes (`mypy headroom`)
- [x] New tests added for new functionality
- [ ] Manual testing performed
### Test Output
```text
$ uvx ruff@0.15.17 check headroom/cli/install.py tests/test_cli/test_install_cli.py
All checks passed!
$ python -m py_compile headroom/cli/install.py tests/test_cli/test_install_cli.py
OK
```
## Real Behavior Proof
- Environment: Windows 11, Python 3.12, `uvx ruff@0.15.17`. Importing
`headroom` pulls in the torch/transformers stack and a full `pytest`
gets OOM-killed on this box, so I verified the access with a
dependency-free script that replicates the old vs guarded lookup, and
left the full pytest (including the new CLI test) to CI.
- Exact command / steps: ran the old `payload.get('config',
{}).get('backend', ...)` and the new guarded lookup against `config`
values of `null`, a string, a list, a proper object, and a missing key.
- Observed result: the old lookup raises `AttributeError` for every
non-dict `config`; the new lookup falls back to the manifest backend for
those and returns the real backend for a proper object (and the
missing-key case is unchanged). The new CLI test drives `install status`
with `probe_json` returning `{"config": null}` and asserts a clean exit
with the manifest backend.
- Not tested: a live foreign service occupying the port; full local
`pytest` deferred to CI (OOM, per above).

## Additional Notes
The "unit tests pass locally" and "type checking" boxes are unchecked
because the full suite imports the ML stack, which I can't run in this
environment; the change adds an `isinstance` guard mirroring an existing
sibling, verified by the standalone proof and a new CLI test that reuses
the file's existing `install status` mocking harness.
