Add Atlas Cloud model provider support

[binyangzhu000-sudo]

Summary

• Add Atlas Cloud to the core model provider registry as an OpenAI-compatible provider using ATLASCLOUD_API_KEY, https://api.atlascloud.ai/v1, and the existing ATLASCLOUD_BASE_URL override convention.
• Add Atlas Cloud to the create-voltagent-app provider selection with default model atlascloud/qwen/qwen3.5-flash.
• Add focused registry/CLI coverage plus a changeset.

Validation

• corepack pnpm install --frozen-lockfile --ignore-scripts (completed; warned about missing local volt bins because package dist files are not built during install)
• corepack pnpm --filter @voltagent/internal build
• corepack pnpm --filter @voltagent/core exec vitest run src/registries/model-provider-registry-atlascloud.spec.ts src/registries/model-provider-registry-minimax.spec.ts (12 passed)
• corepack pnpm --filter create-voltagent-app exec vitest run src/cli.integration.spec.ts (1 passed)
• corepack pnpm --filter @voltagent/core typecheck
• corepack pnpm --filter @voltagent/core build
• corepack pnpm --filter create-voltagent-app build
• corepack pnpm exec biome check packages/core/src/registries/model-provider-registry.ts packages/core/src/registries/model-provider-registry-atlascloud.spec.ts packages/create-voltagent-app/src/types.ts packages/create-voltagent-app/src/cli.ts packages/create-voltagent-app/src/cli.integration.spec.ts
• corepack pnpm exec prettier --check .changeset/atlascloud-provider.md
• git diff --check
• Atlas live model catalog returned 118 models and confirmed qwen/qwen3.5-flash and deepseek-ai/deepseek-v4-pro.

No README changes; no sponsor/logo/credits/partner promotion.

- Around line 5-7: Update the `@voltagent/internal` mock in
model-provider-registry-atlascloud.spec.ts to reuse the actual module
implementation via vi.importActual instead of defining safeStringify with
JSON.stringify. Preserve any required mocked exports while ensuring no direct
JSON.stringify usage remains.

Pushed a follow-up commit addressing the review feedback:\n\n- Reused the real @voltagent/internal implementation in the test mock via vi.importActual instead of reimplementing safeStringify with JSON.stringify.\n- Removed ATLASCLOUD_API_KEY from process.env by rebuilding the env object for the missing-key test, avoiding Node's string "undefined" behavior while keeping Biome happy.\n\nValidation:\n\n- corepack pnpm --filter @voltagent/core exec vitest run src/registries/model-provider-registry-atlascloud.spec.ts (4 passed)\n- corepack pnpm exec biome check packages/core/src/registries/model-provider-registry-atlascloud.spec.ts\n- git diff --check
