feat(examples): add Dedalus Labs and Cloudflare AI Gateway examples

[richardsolomou]

Problem

We don't have runnable examples for tracking Dedalus Labs or Cloudflare AI Gateway traffic in PostHog. Both expose OpenAI-compatible endpoints, so they slot into the existing OpenTelemetry auto-instrumentation pattern we already use for OpenRouter.

Changes

Two new examples under examples/:

• example-ai-dedalus — OpenAI SDK pointed at https://api.dedaluslabs.ai/v1, DEDALUS_API_KEY, models as provider/model-id (e.g. openai/gpt-5-mini).
• example-ai-cloudflare-ai-gateway — OpenAI SDK pointed at the compat endpoint (https://gateway.ai.cloudflare.com/v1/{account_id}/{gateway_id}/compat), upstream provider API key with cf-aig-authorization header for gateway auth, provider/model-id format.

Both follow the same structure as the existing OTel examples (chat.py, pyproject.toml, README.md, uv.toml, uv.lock, .env.example) and stream spans through PostHogSpanProcessor via OpenAIInstrumentor.

Stacked on #482.

How did you test this code?

Ran the Node.js Cloudflare AI Gateway example end-to-end against a real PostHog project and confirmed $ai_generation events land. The Python example follows the same pattern. To verify:

cd examples/example-ai-dedalus
cp .env.example .env  # fill in keys
uv sync && source .env && uv run python chat.py

Comment:
**Likely copy-paste model name from Cloudflare example**

Dedalus Labs is a direct OpenAI-compatible gateway, so the `openai/` provider prefix in `"openai/gpt-5-mini"` is almost certainly a copy-paste from the Cloudflare `compat` endpoint (which _requires_ a provider prefix to route across multiple providers). All other OpenAI-compatible gateway examples in this repo (Helicone, Vercel) use bare model names like `"gpt-5-mini"`. Unless Dedalus Labs explicitly requires this prefix, this should match the standard pattern.

```suggestion
    model="gpt-5-mini",
```

How can I resolve this? If you propose a fix, please make it concise.

Comment:
**`POSTHOG_API_KEY` missing from required-vars list**

The code uses `os.environ["POSTHOG_API_KEY"]` (hard key lookup, not `get`), so it will raise a `KeyError` if unset. The README currently lists only the Cloudflare-specific keys as required, leaving users to discover the missing PostHog key at runtime.

```suggestion
`POSTHOG_API_KEY`, `CLOUDFLARE_ACCOUNT_ID`, `CLOUDFLARE_GATEWAY_ID`, and `OPENAI_API_KEY` are required.
```

How can I resolve this? If you propose a fix, please make it concise.
