feat: add Atlas Cloud provider preset

[binyangzhu000-sudo]

Summary

• add Atlas Cloud to the built-in AI provider preset catalog
• configure its OpenAI-compatible Chat Completions endpoint and default model
• register the routed model semantics and keep credential injection defaults aligned

Verification

• pnpm exec vitest run src/ai-providers/preset-catalog.spec.ts src/ai-providers/model-semantics.spec.ts src/workspaces/cli/shim.spec.ts services/uta/src/domain/trading/brokers/presets.spec.ts (80 passed)
• pnpm exec tsc --noEmit
• full pnpm test: 3828 passed, 9 skipped; two unrelated tests timed out under the full parallel run and passed when rerun in the focused set; the catalog-contract failure found by the full run was fixed before the focused rerun
• parsed the preset and used its endpoint/model with the OpenAI client against the live Atlas Cloud API (123 models; default model present; chat completed)
• git diff --check

@binyangzhu000-sudo is attempting to deploy a commit to the luokerenx4's Team Team on Vercel.

A member of the Team first needs to authorize it.

云端代理审阅（以 upstream dev @ 47e8651b 为准）

结论

仍可行动、值得接，但需重基 + CI 绿。

现状

• presetProviders 仍无 Atlas Cloud；产品需求仍成立。
• 与 dev 有冲突（含 PLANS.md）；需 rebase 到当前 dev。
• Checks：Vercel 授权噪声；项目 CI 未见到结果。

建议

1. Rebase 到 dev，解冲 PLANS.md（不要带无关的计划行）。
2. 确认仅触及 preset / 文档，不扩大到认证核心逻辑。
3. 项目 CI 绿后再合入。

Synced with master (1305 commits). All three conflicts were the same shape — upstream added an openrouter preset in the exact rows this branch adds atlas-cloud:

• preset-catalog.ts → DEFAULT_MODEL_BY_PRESET
• preset-catalog.spec.ts → the two matching expectation objects

Both entries are kept everywhere, openrouter first in upstream's position.

I also checked the auto-merged side rather than assuming a clean merge is a correct one: the atlas-cloud entry in model-semantics.ts came through intact.

Verification on the merged branch:

• vitest run src/ai-providers → 42 passed (3 files)
• tsc --noEmit → clean

No conflicts remain.

Synced with dev — and corrected a mistake in the previous sync on this branch.

This PR targets dev, but the earlier sync merged upstream/master instead. That pulled master's
65 release commits in and put a version bump (0.93.0) and a CI workflow edit into the diff, none of
which belong to an Atlas Cloud preset. Merging dev this time absorbs all of it: the only conflicts
were the two package.json versions, both resolved to dev's 0.93.1-beta, and the diff against
dev is now exactly the three src/ai-providers/ files this PR is about — 64 insertions, down from
6 files / 67.

The preset itself is unchanged. I checked its shape against the other third-party presets in
preset-catalog.ts and it carries the same fields (zodSchema, regions, models, setup,
writeOnlyFields) with no hardcoded pricing or other data that would go stale.

Verified:

• vitest run — 800 files, 7039 passed, 4 skipped, zero failures
• tsc --noEmit — zero errors

Thanks for the review. Re-synced with the current dev (5da8dfc).

1. Rebase / conflicts: ✅ Merged dev into the branch. The only conflicts were the version fields in package.json and packages/cli/package.json; both resolved to dev's values. PLANS.md no longer conflicts.
2. Scope: ✅ The diff against dev is exactly three files under src/ai-providers/ (64 insertions): the atlas-cloud preset, its model semantics, and the catalog spec. No auth or trading code is touched.
3. CI: the only check shown on the PR is the Vercel authorization notice (needs a team member to authorize; unrelated to the code). I could not see the project's own CI results, so I ran the checks locally on the merged tree.

Verified locally: tsc --noEmit is clean; vitest run src/ai-providers src/workspaces/cli/shim.spec.ts services/uta/.../presets.spec.ts gives 7 files, 118 tests passed. A live call using the preset's parsed defaults (base URL + deepseek-ai/deepseek-v4-pro) against the Atlas Cloud gateway returned HTTP 200, and the model id is still listed in /v1/models.
Not run: the full pnpm test suite.
