Description

The inline-edit feature is already supported in the VSCode extension. Users can select some text (optionally), invoke inline-edit (using Ctrl+I or selecting it from the context menu), input an instruction to edit the current file, then review the changes and accept or discard them. We want to support this feature in the IntelliJ plugin as well.

The IntelliJ platform provides a code-intentions-preview api that can be used for reviewing changes and resolving edits. This should be a better approach than manually using color decoration for diffs, which is implemented in the VSCode extension.

The underlying inline-edit implementation is in tabby-agent, which exports an extended LSP method ChatEditRequest. It currently supports output in previewChanges format only (used in VSCode extension). We may need to modify it to support a direct editing format to make the result compatible with the IntelliJ code-intentions-preview API.

Please reply with a 👍 if you want this feature.

Research direction
Examine the existing VSCode inline edit implementation in the tabby agent repository (clients/tabby agent/src/protocol.ts) to understand the ChatEditRequest protocol. Explore the IntelliJ code intentions preview API as mentioned but note the strikethrough suggesting a possible alternative approach. Review any comments on the issue for additional context.
