chore: release v4.5.5

[github-actions]

Summary

5 improvements, 5 bug fixes.

Improvements

• Add experimental Node.js 24 and 26 task runtimes. Set runtime to experimental-node-24 or experimental-node-26 in trigger.config.ts. (#4085)
• Add defaultRegion to the project GET and list API responses; null when unset. (#4146)

Server changes

These changes affect the self-hosted Docker image and Trigger.dev Cloud:

• Transient internal sync failures are now retried quietly instead of surfacing as errors. (#4270)
• Optionally route ClickHouse read traffic to a read replica while writes stay on the primary. Set CLICKHOUSE_READER_URL to move all reads, or target the busiest paths with RUNS_LIST_CLICKHOUSE_URL (runs list) and EVENTS_READER_CLICKHOUSE_URL (traces, spans, logs). All optional; unset keeps current behavior. (#4081)
• Remove the deprecated realtime stream write endpoint used by retired v3 task clients. (#4250)
• Fix batchTrigger requests that set a per-item idempotency key failing with an error instead of creating and deduplicating the runs (#4271)
• Speed up idempotency checks on batchTrigger calls that use idempotency keys. Large batches against a task with a big run history no longer degrade to multi-second lookups. (#4255)
• The "Preview branches" usage on the Limits page now counts only preview branches. (#4283)
• Avoid opening a redundant database connection pool when the legacy and primary databases are the same server, preventing connection usage from doubling. (#4253)
• Fix pages occasionally loading unstyled or failing to load during a deploy. The dashboard now reloads automatically to recover. (#4282)
