## What's changed

## Improvements
- Show schedule policy warnings during development and deployment, and present Free plan schedule limits without internal stack traces. ([`723fde4a8`](https://github.com/triggerdotdev/trigger.dev/commit/723fde4a86b8b57ba7b037a04a7147c45f5287b8))
- New CLI commands: `projects create/get/rename`, `runs list/get/replay/cancel`, and `env set` ([`5bcd1a9fa`](https://github.com/triggerdotdev/trigger.dev/commit/5bcd1a9faf79c5b07598c43d0f935506b182b53b))
- Warn when a deployment uses the deprecated Node.js 21 runtime. Deployment logs now include upgrade guidance, and the account associated with the deployment receives an email notification. ([`053b0b4c6`](https://github.com/triggerdotdev/trigger.dev/commit/053b0b4c62bc4b650b8d4f6aa692bc0ca669567a))

## Bug fixes
- Fix the MCP server failing every `tools/list` call with "Date cannot be represented in JSON Schema" ([`6c90639f2`](https://github.com/triggerdotdev/trigger.dev/commit/6c90639f2f52b1dfdcc119f348aa33cbc015c060))

## Server changes

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

- The assistant in the dashboard now answers with cards: investigation cards for run questions, carrying the run's timeline and links to the run, queue or deployment, alongside charts and tables you can open fullscreen or copy — including queue metrics — and it answers about another project or environment without you switching to it first. The assistant reads run timelines through a dedicated endpoint, so span durations and launch events are consistent on every event store; the public run trace API is unchanged.
- Warn when Production projects still use Node.js 21 and link directly to update instructions
- Deployments now show the runtime their worker actually reported, so Bun deployments are no longer labelled Node.js; a deployment with no recorded runtime shows a dash instead of a guess.
