1. 添加自定义压缩(总结)模型默认项 Add DEFAULT_COMPRESS_MODEL configuration

2. 将 compress model 设置项的样式与 model 设置项的样式统一 Align the style of the compress model setting with that of the model setting.

📝 补充信息 | Additional Information

I also noticed that both 'compress' and 'summary' appear in the code. Should I merge them into 'summary' in this PR? 还有我注意到代码中存在compress和summary这两个词汇同时存在，需要顺便在我这个PR将其合为一个summary?

Walkthrough

The changes introduce a new optional configuration parameter, DEFAULT_COMPRESS_MODEL, across multiple files. This variable is added to the environment template, documented in README files (including Chinese and Japanese versions), and integrated into both server-side configuration and frontend state management. The updates include adjustments to API configuration, conditional logic in the chat module, and UI enhancements for model selection grouping. The modifications ensure that the compression model setting flows from environment definition through to the application’s configuration and display logic.

Changes

File(s)	Change Summary
.env.template	Added new optional environment variable DEFAULT_COMPRESS_MODEL with a default empty value.
README.md, README_CN.md, README_JA.md	Updated documentation: added description for DEFAULT_COMPRESS_MODEL; removed description for STABILITY_URL (in README.md); clarified sections such as VISION_MODELS (in README_CN.md).
app/api/config/route.ts	Added new property defaultCompressModel to the DANGER_CONFIG object and updated the DangerConfig type definition.
app/config/server.ts	Extended the ProcessEnv interface and updated getServerSideConfig to handle DEFAULT_COMPRESS_MODEL, including logic to reset this value when GPT-4 models are disabled.
app/store/access.ts	Introduced new defaultCompressModel property in DEFAULT_ACCESS_STATE and modified the fetch logic to update the model configuration based on the received value from the server.
app/store/chat.ts	Modified the getSummarizeModel function to conditionally return the compressModel and its provider if defined in the configuration, adjusting the selection flow.
app/components/model-config.tsx	Updated the model selection rendering to group models by their provider using the groupBy function from lodash-es, enhancing the clarity of options in the user interface.

Poem

I'm a bunny with a curious code delight,
Hopping through configs from morning till night.
A new compress model now joins my garden so fair,
Guiding my code with gentle, playful care.
With whiskers twitching in lines of pure cheer, I celebrate these changes, oh dear!

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

Why isn't it fit? To this day, many models are summarized by themselves.
