Describe the enhancement you want to request

We request desktop support for pre-filling input fields using the opencode://append?text=xxx URL scheme parameter.

The goal is to enable interaction between the IDE plugin and the desktop client; currently, the server only supports TUI interaction.

This issue might be a duplicate of existing issues. Please check:

• Feature Request: Desktop app deep links (opencode://session/<id>) #6232: Feature Request: Desktop app deep links (opencode://session/) — also requests URL scheme support for the desktop app via Tauri's deep-link plugin, though that issue focuses on session linking rather than pre-filling the prompt input.

此问题可能与现有问题重复。请检查：

• 功能请求：桌面应用程序深度链接 (opencode://session/)  #6232：功能请求：桌面应用程序深度链接 (opencode://session/) — 还请求通过 Tauri 的深度链接插件为桌面应用程序提供 URL 方案支持，尽管该问题侧重于会话链接，而不是预填充提示输入。

I noticed that some features have already been added. Could you please consider adding an input field fill function for interaction with the IDE?
