[microsoft/vscode] Linkification broken in gpt-5.4

### ROOT CAUSE The issue arises because links are not formatted correctly using Markdown syntax. Instead of the proper `[display text](url)` format, links are presented as plain URLs within square brackets, preventing proper linkification. ### CODE FIX To fix the broken linkification, ensure all links follow the proper Markdown format. Here's an example of the corrected syntax: ```typescript The main chat contract is [Main Chat Contract](vscode2/src/vs/workbench/contrib/chat/common/chatService/chatService.ts#L1345), and the implementation is [Chat Implementation](vscode2/src/vs/workbench/contrib/chat/common/chatService/chatServiceImpl.ts#L97). ``` **Note:** Apply this format to all links in the codebase to enable proper link rendering.
