## Description
This PR fixes the reply editor staying at its default height when
Copilot generates a suggestion, causing longer suggestions to be clipped
after a line or two.
The editor now automatically grows to fit the suggestion, up to a
maximum of 350px, and returns to the height it had before the suggestion
when it is accepted or discarded. Manual resizing continues to work as
expected and always takes priority.
### How to reproduce
1. Open a conversation and generate a Copilot suggestion (✨ → Summarize
the conversation).
2. The reply editor stays at its default height and the suggestion gets
clipped after a line or two.
3. Resize the reply editor, generate another suggestion, and discard it.
The editor no longer returns to the height you set.
### What changed
* `CopilotEditor` measures the rendered suggestion and requests enough
space to display it, capped at 350px. The requested height is released
when the suggestion is gone.
* `ResizableEditorWrapper` handles this requested height separately from
the manually dragged height, so the suggestion can grow the editor
without overriding the user's preferred height.
* The loading and suggestion states now cross-fade in place while the
editor resizes, instead of briefly switching through an empty card.
