feat(model): add Atlas Cloud provider

[binyangzhu000-sudo]

Description

Adds Atlas Cloud as a first-class OpenAI-compatible model provider. The preset uses https://api.atlascloud.ai/v1/, which resolves through the existing runtime to /v1/chat/completions, and includes three currently available text models:

• deepseek-ai/deepseek-v4-pro
• deepseek-ai/deepseek-v4-flash
• qwen/qwen3.5-flash

The integration reuses the existing OpenAI-compatible driver and provider artwork; no README, documentation, logo, sponsor, credits, or partner content was added.

Verification

• npm install --package-lock=false --ignore-scripts
• npx prettier --check src/module/Model/providers.ts src/module/Model/models.ts
• npx vite build
• focused runtime URL assertion: https://api.atlascloud.ai/v1/ -> https://api.atlascloud.ai/v1/chat/completions
• live Atlas Cloud /v1/models: 121 models; all three presets confirmed
• git diff --check

npx vue-tsc --noEmit is currently blocked by the repository project reference requiring an unbuilt src/config.d.ts. Building that reference also reports pre-existing project-wide type/dependency errors in unrelated Electron and dependency files.
