Accept changes without switching back to coding agent

[fky2015]

First of all, thanks for your work!

In the current workflow, a user needs to manually switch back to Coding Agent to confirm the change. But that could be a burden if there are lots of changes pending.

When users use coding agent with code, they care about editing and the files that changed. So it would be a more fluent design to be able to keep all the operations inside Neovim.

So IMHO, we can further improve the hook to let Neovim's Lua function trigger an approval. And there are projects like https://github.com/farouqaldori/vibe-notch that have already achieved the similar feature.

Just to throw out an idea 😄.
