Forwarding was wired tool by tool, so only the first eleven tools took
environmentId. It now lives in McpToolAccess.toLayer: a tool whose
parameters take OrchestratorMcpEnvironmentTarget runs in the linked
environment it names once its declaration has checked the caller here.
The local handler never sees environmentId. Tools that act as the calling
thread itself cannot take one, and the layer refuses to build if they do.

Queues, pending requests, thread settings and organizing, forks and
merge-backs, scheduled tasks, pull requests, worktree refs, project
read/update/delete and environment preferences now reach a link too.
