* fix(github-copilot): bound model discovery and embeddings JSON response reads
The GitHub Copilot embeddings plugin already bounds its error response
bodies via readResponseTextLimited, but the success JSON reads for both
model discovery and the embeddings call used unbounded response.json().
Route both through readProviderJsonResponse (16 MiB cap).
Update isCopilotSetupError to recognise the new error label prefix so
auto-selection still falls through on malformed discovery responses.
Update tests to use proper Response objects and the new error messages.
AI-assisted.

Fixes Copilot image understanding by exchanging OAuth tokens for Copilot API tokens, routing Copilot Gemini image requests through Chat Completions, and sending the prompt in user content with Copilot vision headers.
Real behavior proof:
- Old Responses route with real Copilot key reproduced `400 model gemini-3.1-pro-preview does not support Responses API`.
- Fixed route with the same real Copilot key returned `Cat`.
- Final CLI live smoke returned `ok: true` and `text: Cat` for `github-copilot/gemini-3.1-pro-preview`.
Verification:
- pnpm test src/media-understanding/image.test.ts extensions/github-copilot/models.test.ts extensions/github-copilot/stream.test.ts src/agents/pi-hooks/compaction-safeguard.test.ts -- --reporter=verbose
- pnpm check:changed via Blacksmith Testbox tbx_01krgt56pqmft8txekt017wke6, Actions run https://github.com/openclaw/openclaw/actions/runs/25803926150, exit 0.
