Merged: No

What does this PR do?

Introduce Programmatic Tool Calling (PTC) support for plugins, enabling plugins to invoke tools directly within a session without relying on LLM vendor-specific APIs.

This change exposes a unified tool invocation API that:

  • Allows plugins to execute tools programmatically
  • Reduces LLM round-trips and token consumption
  • Decouples plugin PTC implementation from underlying model providers (e.g. Anthropic-specific APIs)

To support this, the JS SDK (v1/v2) is regenerated to expose the new execute API and related types, allowing plugin authors to implement PTC in a provider-agnostic way.

Without this change, plugins in opencode can only achieve PTC via vendor-dependent LLM APIs and cannot invoke tools directly.

Closes https://github.com/anomalyco/opencode/issues/4713

How did you verify your code works?

I've written a POC plugin to wrap the tools into async javascript functions, and the model is able to create 10k TODOs or 10 subtasks concurrently with the new interface.

Because it currently depends on a local SDK version, it has not been released yet. I will complete it as soon as possible and open-source it under the MIT license.
