Images and GitHub issues/PRs now live in one draft-store list (ComposerAttachment union) with cwd persisted on the draft. Paperclip becomes a + drop-up menu; queue button removed. Each pill uses a shared AttachmentPill wrapper with a corner-X that mirrors the auto-update toast spec. Pill body opens the attachment: GitHub via openExternalUrl, images via a new fullscreen AttachmentLightbox. GitHub picker auto-closes on select.
The Create button on the new workspace screen was visible but clicking
it did nothing — submitAgentInput() still rejected empty payloads as
"noop". Thread allowEmptySubmit through Composer into submitAgentInput
so the callback fires and workspace creation + redirect completes.
Adds regression test for the empty-submit path.
submitAgentInput returned "noop" for empty messages regardless of
allowEmptySubmit, breaking the new-workspace empty-submit flow.
Now the flag is passed from Composer through to submitAgentInput
so empty submissions are allowed when the prop is set.
Narrow zustand selectors to only subscribe to fields each component
actually uses. Split nested objects (availableModes, projectPlacement)
into separate selectors with structural equality checks. Remove the
updatedAt processing-spinner hack in agent-input-area — the server
already guarantees agent status is "running" before ACKing the send
request, so isProcessing can clear on submit success directly.
