Walkthrough

The changes introduce enhanced focus management for the chat input editor. A new disabled prop and a publicly exposed restoreFocus method are added to ChatInput.vue. Focus restoration is triggered after sending messages, on visibility changes, and when the input is re-enabled, coordinated with ChatView.vue to ensure the editor regains focus in key scenarios.

Changes

Cohort / File(s)	Change Summary
Chat Input Focus Management src/renderer/src/components/ChatInput.vue	Adds disabled prop, exposes restoreFocus method, modifies focus handling to remove blur on send, and adds watchers for visibility and disabled state to restore focus. Internal helper functions are nested within restoreFocus.
Chat View Integration src/renderer/src/components/ChatView.vue	Adds a ref to ChatInput and calls restoreFocus after sending messages and on stream end/error events to maintain input focus.

Poem

A rabbit hops where chat flows free,
Restoring focus—quick as can be!
When messages send or errors appear,
The editor’s ready, the cursor is near.
With props and methods, all in tune,
Your chat stays lively—morning to noon!
