Release v0.51.283 — Release IY (stage-w2 — composer queue hint during auto-compaction #3512) (#3690)

* feat(composer): surface that messages queue during auto-compaction (#3512, #3079)

Co-authored-by: Rod Boev <rod.boev@gmail.com>

* docs(changelog): v0.51.283 — Release IY (stage-w2)

* fix(composer): restore placeholder on ALL compaction-exit paths, not just clearCompressionUi (#3512)

Codex+Opus both caught: setCompressionUi(done) and the live-anchored SSE
window._compressionUi=null paths bypassed clearCompressionUi, leaving the
'will queue' placeholder stuck after compaction. Factor restore into
_restoreCompressionPlaceholder() + call from every compaction-exit path.

 ## [Unreleased]
 
+## [v0.51.283] — 2026-06-05 — Release IY (stage-w2 — composer queue hint during auto-compaction)
+
+### Fixed
+- **The composer now tells you a message will queue during auto-compaction instead of looking dead.** While automatic compression runs, the send button previously went `disabled` with only a "Waiting for compression to finish" tooltip. It now shows a `queue` action with the placeholder + tooltip "Type a message — it will queue and send after compression", so you can type and have it sent automatically when compaction completes. (#3512, @rodboev; closes #3079)
+
 ## [v0.51.282] — 2026-06-05 — Release IX (stage-3544 — surface memory/skill saves in Activity summary)
