Is your feature request related to a problem? Please describe.

The @trigger.dev/sdk currently has a peer dependency on ai@^4.2.0 || ^5.0.0, which prevents using the latest Vercel AI SDK 6.x alongside Trigger.dev.

When attempting to install both:

npm error ERESOLVE could not resolve
npm error While resolving: @trigger.dev/sdk@4.3.2
npm error Found: ai@6.0.42
npm error   peer ai@"^4.2.0 || ^5.0.0" from @trigger.dev/sdk@4.3.2

Using --legacy-peer-deps to force the install causes cascading issues where other packages fail to install correctly.

Describe the solution you'd like to see

Update the peer dependency to include AI SDK 6:

"ai": "^4.2.0 || ^5.0.0 || ^6.0.0"

And update any internal usage to be compatible with the SDK 6 API changes (e.g., toDataStreamResponse() → toTextStreamResponse(), maxTokens → maxOutputTokens).

Describe alternate solutions

Currently we're forced to stay on AI SDK 5, which works but means missing out on SDK 6 improvements and features.

Additional information

AI SDK 6 was released recently and includes:

• New response streaming APIs
• Updated model configuration options
• Various performance improvements

Related discussion: The AI SDK transport feature request (#2634) also references SDK v5, so SDK 6 support would benefit that work as well.
