Feature request: support input-method and text-input protocols

[chirsz-ever]

Hi, I’m opening this issue to request support for the input-method and text-input Wayland protocols in cage. These protocols are essential for enabling proper text input and input method (IME) integration, which is crucial for applications that require multilingual or complex text input (e.g., CJK languages, emoji pickers, etc.).

Currently, without support for these protocols, applications running under cage may not be able to interact with input methods, leading to a poor user experience in scenarios where text input is required.

I expect cage to implement the input-method-v2 and text-input-v3 protocols which are directly supported in wlroots¹².
