feat(providers): add GMI Cloud provider preset and partner listing

[kevincodex1]

Summary

Adds GMI Cloud (https://www.gmicloud.ai/) as an OpenAI-compatible provider preset and as an official partner in the README. The matching OpenClaude change is Twigpine/openclaude#2279 (merged).

• Provider gmicloud at https://api.gmi-serving.com/v1:
  • zero providers setup gmicloud --set-active; gmi-cloud, GMI Cloud and gmi resolve to the same preset.
  • The id matches the models.dev provider id (gmicloud), so the remote model catalog resolves without a mapping.
  • Reads GMI_API_KEY (the name in GMI's docs) and GMICLOUD_API_KEY (the name models.dev uses).
  • Defaults to Qwen/Qwen3.8-Max. The curated list is Qwen 3.8 Max and Qwen 3.8 Flash (GMI's partner models), then DeepSeek V4 Pro and DeepSeek V4 Flash (GMI's coding picks). All four are on GMI's live /v1/models.
• Partner: GMI Cloud is added to the Partners table in README.md and README_ZH.md, with light and dark logos vendored under docs/assets/.
• Docs: both READMEs get the GMI_API_KEY line and the setup command.

Small, catalog-only change: one preset line, one curated model list and tests. No transport or request code changes.

Verification

• make fmt-check, go vet ./..., go test ./..., go run ./cmd/zero-release build, go run ./cmd/zero-release smoke, make vulncheck and git diff --check pass.
• make lint-static reports only the 4 pre-existing staticcheck findings in files this PR does not touch.
• New and updated tests:
  • descriptor contract (TestGMICloudDescriptor);
  • alias resolution (GMI Cloud, gmi-cloud, gmi);
  • catalog and transport ordering;
  • curated models;
  • the onboarding block.
• Live, with a real GMI key (isolated HOME/XDG dirs, branch build):
  • zero providers add gmicloud --api-key-env GMI_API_KEY --set-active, then zero providers check gmicloud --connectivity: status: ok, connectivity: pass (200) on Qwen/Qwen3.8-Max.
  • zero exec --auto medium on a real read-then-write task (read notes.txt, write the secret word to answer.txt, reply DONE):
    • Qwen/Qwen3.8-Max: pass, 19 s;
    • Qwen/Qwen3.8-Flash: pass, 12 s.
  • With a dummy key, the connectivity check surfaces GMI's own 401 {"error":"Invalid API key"} with a clear next step.
