chore: release v4.5.0

[github-actions]

Summary

4 improvements.

Improvements

• Adds the Sessions primitive — a durable, run-aware stream channel keyed (#3542)
• Reject overlong idempotencyKey values at the API boundary so they no longer trip an internal size limit on the underlying unique index and surface as a generic 500. Inputs are capped at 2048 characters — well above what idempotencyKeys.create() produces (a 64-character hash) and above any realistic raw key. Applies to tasks.trigger, tasks.batchTrigger, batch.create (Phase 1 streaming batches), wait.createToken, wait.forDuration, and the input/session stream waitpoint endpoints. Over-limit requests now return a structured 400 instead. (#3560)
• Retry TASK_PROCESS_SIGSEGV task crashes under the user's retry policy instead of failing the run on the first segfault. SIGSEGV in Node tasks is frequently non-deterministic (native addon races, JIT/GC interaction, near-OOM in native code, host issues), so retrying on a fresh process often succeeds. The retry is gated by the task's existing retry config + maxAttempts — same path TASK_PROCESS_SIGTERM and uncaught exceptions already use — so tasks without a retry policy still fail fast. (#3552)
• The public interfaces for a plugin system. Initially consolidated authentication and authorization interfaces. (#3499)

@trigger.dev/sdk@4.5.0

Minor Changes

• Adds the Sessions primitive — a durable, run-aware stream channel keyed (#3542)
  on a stable externalId. Public SDK additions: tasks.triggerAndSubscribe()
  and the chat.agent runtime built on top of Sessions. See
  https://trigger.dev/docs/ai-chat/overview for the full feature surface.
