Wrap the streaming Enter steer dispatch in try/catch so prompt failures restore text plus pendingImages / pendingImageLinks / imageLinks and surface showError instead of losing an image-only draft.\n\nAlso remove a forbidden ReturnType<> from the follow-up image regression helper.\n\nFixes #3467
Snapshot pendingImageLinks alongside pendingImages at the top of handleFollowUp and wrap both the streaming and idle session.prompt dispatches in try/catch that restores text + pendingImages + pendingImageLinks + imageLinks and surfaces showError, mirroring the main submit and focused submit error paths so an image-only or text+image Ctrl+Enter draft survives dispatch rejection.\n\nFixes #3467
Treat pending pasted images as submit content in the main and focused input controller paths so image-only Enter/Ctrl+Enter submissions queue instead of dropping or aborting.\n\nFixes #3467
- Centralized draft state and image management by migrating fields from context to the CustomEditor component.
- Standardized transcript row construction by introducing shared helpers for background jobs, IRC traffic, and file mentions.
- Refactored redundant UI logic and helper functions into reusable utility modules to streamline message submission and component rendering.
- Standardized event handler types by consolidating lifecycle definitions into a shared module while maintaining public API stability.
- Passed pending and input images into compaction queueing for steering and follow-up flows.
- Delivered queued follow-up/steer prompts with stored images via session.prompt and followUp.
- Normalized empty image arrays to undefined and cleared stale pending image state.
- Added regression tests for image-backed compaction queueing and follow-up forwarding.
