chore: release v4.5.2

[github-actions]

Summary

4 improvements, 5 bug fixes.

Improvements

• Add SDK and API client helpers for run bulk actions. (#4105)

• Large batch payloads now offload to object storage instead of riding inline in the trigger request. batchTrigger and batchTriggerAndWait (and the by-id and by-task variants) offload any per-item payload over 128KB before sending, the same way single trigger and triggerAndWait already do, so a big batch no longer blows past the API body limit. (#4165)

• Removed internal helpers that were only used by the end-of-life v3 self-hosted compute providers. (#4194)

• Add an onEvent callback to TriggerChatTransport / useTriggerChatTransport that emits typed lifecycle events for sends, stream connects, first chunk, and turn completion. Send-success metrics, time-to-first-token, and "sent but never answered" watchdogs become a few lines of client code. (#4187)

  onEvent: (event)=>{if(event.type==="message-sent")metrics.timing("chat.send_ms",event.durationMs);if(event.type==="first-chunk")metrics.timing("chat.ttft_ms",event.sinceSendMs??0);},

Bug fixes

• fix(cli): honor the MCP server's --dev-only flag (#4199)
• Fix chat turns that throw (for example from an onTurnStart hook) leaking their message listener, which lost or duplicated messages sent during later turns. (#4176)
• Fix chat.agent and chat.createSession permanently dropping user messages when several arrived during a single turn: every buffered message is now dispatched as its own turn instead of only the first. (#4176)
• Fix chat continuation runs replaying already-answered messages: turns delivered while the run was suspended now advance the session.in resume cursor, so a new run picks up exactly where the previous one left off. (#4176)
• Fix chat.createSession swallowing a message sent shortly after stopping a turn: the turn's message listener now detaches when the stream settles, so those messages run as the next turn. (#4176)
