P1: Define SDK-facing environment discovery RPCs

[BunsDev]

Goal

Start SDK environment support with read-only discovery before attempting create/delete/provisioning.

The SDK design includes local, Gateway, node, managed, and ephemeral environments. Apps should be able to discover what is available without relying on implementation details.

Proposed first methods

• environments.list
• environments.status

Acceptance criteria

• SDK can list available local/node/managed environment candidates.
• Each environment reports status and capabilities.
• Create/delete remain unsupported until managed environment semantics are firmer.
• Unsupported runtime/environment run options continue to fail loudly.

Dogfood update from 2026-05-02:

P1 SDK surface probe results:

• artifacts.list via SDK: live Gateway returned unknown method: artifacts.list.
• raw artifacts.list: live Gateway returned unknown method: artifacts.list.
• tasks.list via SDK: SDK reports this is not supported by the current Gateway yet.
• raw tasks.list: live Gateway returned unknown method: tasks.list.
• environments.list via SDK: SDK reports this is not supported by the current Gateway yet.

Assessment:

• Keep these as design/proposal issues for now.
• They are not blockers for the P0 OpenMeow chat/run/cancel dogfood path.

Compatibility update: openclaw/openclaw#74867 has now merged for openclaw/openclaw#74708. I will use this existing issue for the OpenMeow SDK adapter follow-through rather than opening a duplicate. Scope: expose read-only environment discovery through the adapter, update type declarations, add tests, and refresh docs while leaving create/delete and run-level environment provisioning unsupported.
