Add worktree-aware workspace runtime support

packages/adapters/claude-local/src/index.ts

@@ -25,8 +25,13 @@ Core fields:
 - command (string, optional): defaults to "claude"
 - extraArgs (string[], optional): additional CLI args
 - env (object, optional): KEY=VALUE environment variables
+- workspaceStrategy (object, optional): execution workspace strategy; currently supports { type: "git_worktree", baseRef?, branchTemplate?, worktreeParentDir? }
+- workspaceRuntime (object, optional): workspace runtime service intents; local host-managed services are realized before Claude starts and exposed back via context/env
 
 Operational fields:
 - timeoutSec (number, optional): run timeout in seconds
 - graceSec (number, optional): SIGTERM grace period in seconds
+
+Notes:
+- When Paperclip realizes a workspace/runtime for a run, it injects PAPERCLIP_WORKSPACE_* and PAPERCLIP_RUNTIME_* env vars for agent-side tooling.
