Harden OpenClaw plugin proxy routing (#1074)

Browse source 
## Description

Hardens the bundled OpenClaw plugin so configured proxy routing is
fail-closed and `autoStart` is opt-in.

Closes: N/A

This follow-up is intentionally separate from the ContentRouter cache
fix because it changes plugin/gateway behavior rather than core
compression routing.

The plugin should not mutate upstream provider routing unless a
configured proxy URL is reachable and looks like Headroom. It should
also avoid unhandled startup promise rejections when proxy startup is
fire-and-forget.

Why this shape:

- `autoStart: false` by default matches deployments where Headroom is
supervised externally, for example by systemd. The plugin should not
silently start or assume ownership of a proxy unless the operator opted
in.
- Provider routing is fail-closed: a configured URL must first respond
like Headroom, not merely expose a generic liveness endpoint. This
prevents accidentally routing model traffic through the wrong local
service.
- `/readyz` is treated as liveness, not identity. Identity comes from
Headroom-shaped stats endpoints (`/v1/retrieve/stats` or `/stats`)
because those are harder for unrelated services to satisfy by accident.
- Startup remains asynchronous, but errors are captured and exposed
instead of becoming unhandled promise rejections.
- This is a separate PR because the core cache fix is about compression
correctness, while this patch is about integration safety around
OpenClaw gateway routing.

## Type of Change

- [x] Bug fix (non-breaking change fixes issue)
- [ ] New feature (non-breaking change adds functionality)
- [ ] Breaking change (fix or feature would cause existing functionality
change)
- [ ] Documentation update
- [ ] Performance improvement
- [ ] Code refactoring (no functional changes)

## Changes Made

- Make proxy `autoStart` opt-in (`default: false`).
- Probe configured `proxyUrl` before applying provider routing.
- Treat `/readyz` as liveness only; require Headroom-shaped
`/v1/retrieve/stats` or `/stats` for identity.
- Observe fire-and-forget startup promise rejection and expose startup
error for callers.
- Isolate proxy-ready listener failures.
- Keep provider routing deferred when no active/probed Headroom proxy
exists.
- Register retrieve tool with explicit `headroom_retrieve` name.
- Extend plugin/unit tests for configured proxy failures, generic
non-Headroom endpoints, path collisions, and routing behavior.

Changed files:

- `plugins/openclaw/README.md`
- `plugins/openclaw/openclaw.plugin.json`
- `plugins/openclaw/src/engine.ts`
- `plugins/openclaw/src/plugin/index.ts`
- `plugins/openclaw/src/proxy-manager.ts`
- `plugins/openclaw/test/engine.test.ts`
- `plugins/openclaw/test/gateway-config.test.ts`
- `plugins/openclaw/test/plugin-runtime-routing.test.ts`
- `plugins/openclaw/test/proxy-manager.test.ts`

## Testing

- [x] Unit tests pass (`pytest`)
- [x] Linting passes (`ruff check .`)
- [x] Type checking passes (`mypy headroom`)
- [x] New tests added new functionality
- [x] Manual testing performed

### Test Output

```text
$ npm test

Test Files  6 passed (6)
Tests  74 passed (74)

$ npm run typecheck
tsc --noEmit

$ npm run build
tsup && node prepare-dist.mjs
Build success
```

## Real Behavior Proof

- Environment: local OpenClaw plugin package in the Headroom repo.
- Exact command / steps:
  - Run plugin test suite.
  - Run TypeScript typecheck.
  - Run plugin build.
- Observed result:
  - Tests passed: `74/74`.
  - Typecheck passed.
  - Build passed.
- Not tested:
- Full OpenClaw Gateway integration as part of this standalone PR prep.

Default `proxyPort` is `8787`. Auto-start is opt-in; in production, prefer an externally
managed proxy such as systemd with `proxyUrl` set and `autoStart: false`.
### Upstream gateway routing
By default, the plugin also rewrites the built-in `openai-codex` provider base URL to the active Headroom proxy at runtime. That means Codex provider traffic flows through Headroom, so `/stats` can observe real upstream request and cache activity instead of only local context compression.
By default, the plugin also rewrites the built-in `openai-codex` provider base URL to a verified active Headroom proxy at runtime. That means Codex provider traffic flows through Headroom, so `/stats` can observe real upstream request and cache activity instead of only local context compression.
This does not replace Headroom's existing Codex routing rules. The proxy already decides between `api.openai.com` and `chatgpt.com/backend-api/codex/responses` based on ChatGPT auth. The plugin change only points OpenClaw's provider config at the active proxy in memory and preserves the rest of the provider config.
