chore: release v4.5.12

[github-actions]

Summary

1 new feature, 4 improvements, 4 bug fixes.

Highlights

• Define stable execution windows on declarative scheduled tasks. Schedule API responses now expose both the nominal CRON time and its assigned time, while the dashboard shows configured windows and upcoming assignments. (#4572)

Improvements

• Deployment builds now use custom base layer images and no longer install system packages during every build. This improves layer caching resulting in both faster deployments and faster image pulls on the worker cluster side. (#4602)
• Task metrics no longer go missing for projects that configure their own metricExporters or metricReaders, and the flush error that came with it is gone. (#4613)
• Fair queue tenants can no longer get permanently stuck behind leaked concurrency slots. Slots are now freed on every path that finishes a message, a failed release no longer causes a message to run twice or lose its retry, and a background sweep frees any slot that does leak, so a tenant's queues recover on their own instead of needing manual cleanup. (#4540)

Server changes

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

• Dashboard pages load faster on projects with many preview branches by no longer loading every environment on each page. (#4606)
• Fixed a brief window after promoting or rolling back a deployment where newly triggered runs could still execute on the previous version. New runs now pick up the current version immediately. (#4622)
• Root API keys no longer show an environment creation timestamp as their creation date. (#4612)
• The app version shown on the organization settings page now reports the real version instead of v0.0.0. (#4611)
• Fix paused environments starting to run work again after a deploy: a paused environment now stays paused until you resume it. (#4625)

🔍 Server-change notes consumed without appearing in any committed changelog

This release commit deletes five .server-changes/*.md files (webapp fixes/improvements) via scripts/cleanup-server-changes.mjs (wired into package.json:51). Per .server-changes/README.md, these are supposed to be surfaced in the release PR summary before cleanup, but the PR body here only lists the changeset-derived package notes — none of the five server-only entries (paused environments, dequeue worker version freshness, root API key creation date, org settings app version, bound env layout) appear anywhere in the PR description or in a committed changelog file. Worth confirming the release-notes pipeline actually captures them before the files are deleted, otherwise those user-facing webapp fixes are silently dropped from release notes.
