TUI: coalesce multiline paste submits on macOS terminals

CHANGELOG.md

@@ -20,6 +20,7 @@ Docs: https://docs.openclaw.ai
 - Agents/Ollama: preserve unsafe integer tool-call arguments as exact strings during NDJSON parsing, preventing large numeric IDs from being rounded before tool execution. (#23170) Thanks @BestJoester.
 - Cron/Gateway: keep `cron.list` and `cron.status` responsive during startup catch-up by avoiding a long-held cron lock while missed jobs execute. (#23106) Thanks @jayleekr.
 - Gateway/Config reload: compare array-valued config paths structurally during diffing so unchanged `memory.qmd.paths` and `memory.qmd.scope.rules` no longer trigger false restart-required reloads. (#23185) Thanks @rex05ai.
+- TUI/Input: enable multiline-paste burst coalescing on macOS Terminal.app and iTerm so pasted blocks no longer submit line-by-line as separate messages. (#18809) Thanks @fwends.
 - Gateway/Pairing: treat operator.admin pairing tokens as satisfying operator.write requests so legacy devices stop looping through scope-upgrade prompts introduced in 2026.2.19. (#23125, #23006) Thanks @vignesh07.
 - Memory/QMD: add optional `memory.qmd.mcporter` search routing so QMD `query/search/vsearch` can run through mcporter keep-alive flows (including multi-collection paths) to reduce cold starts, while keeping searches on agent-scoped QMD state for consistent recall. (#19617) Thanks @nicole-luxe and @vignesh07.
 - Chat/UI: strip inline reply/audio directive tags (`[[reply_to_current]]`, `[[reply_to:<id>]]`, `[[audio_as_voice]]`) from displayed chat history, live chat event output, and session preview snippets so control tags no longer leak into user-visible surfaces.
