Subject: [PATCH] feat(dashboard,sse): add OpenCode Free provider (noAuth,
 public endpoint)

Adds 'opencode' to FREE_PROVIDERS as a no-auth provider using the public
OpenCode endpoint (https://opencode.ai/zen/v1). The existing OpencodeExecutor
already skips the Authorization header when no API key is present. Registry
entry reuses the opencode executor and shares models from the zen/v1 endpoint.
