Add worktree-aware workspace runtime support

 - command (string, optional): defaults to "codex"

+- 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 Codex starts and exposed back via context/env

 - Prompts are piped via stdin (Codex receives "-" prompt argument).
 - Paperclip auto-injects local skills into Codex personal skills dir ("$CODEX_HOME/skills" or "~/.codex/skills") when missing, so Codex can discover "$paperclip" and related skills.
 - Some model/tool combinations reject certain effort levels (for example minimal with web search enabled).
+- When Paperclip realizes a workspace/runtime for a run, it injects PAPERCLIP_WORKSPACE_* and PAPERCLIP_RUNTIME_* env vars for agent-side tooling.
