* fix(discord): guard progress draft collapse to prevent re-collapse on cleaned stream
Commit 86ea382 added a progressDraftStartedBeforeFinal latch that snapshots
hasStarted at markFinalReplyStarted time. This correctly preserves collapse
eligibility when an abort cancels the compositor gate before
shouldCollapseProgressDraft runs.
However the latch was never cleared. After markPreviewFinalized turned the
draft into a summary, hasProgressDraftStarted remained true permanently. In
multi-tool turns with multiple final-payload deliveries, this caused
shouldCollapseProgressDraft to re-trigger collapse on an already-cleaned or
sealed draft stream, corrupting downstream delivery state and causing tool
results to render as image content blocks instead of text.
Fix: add a progressDraftCollapsed guard set by markPreviewFinalized that
prevents hasProgressDraftStarted from returning true after the draft has been
collapsed into a summary. Reset the guard on handleAssistantMessageBoundary
so followup/queued turns start fresh.
Per Discord channel session, all tool results rendered as image content
blocks. Model received (see attached image) placeholders instead of text.
