feat(p2): tools declare who may call them and where, turn origin from the run's inputs, agents give their own tools
- P2Tool: origin (any|owner) and scope (any|main|subagent) on the tool; the worker's
  Durable registry checks them before each call (guardTool), no tool checks itself.
  owner: location tools, reload_plugins, conversations, ports, MCP tools.
  main: subagent, rename_session, conversations, ports, reload_plugins. subagent: team.
- originOf reads pi.live.run.inputs through tx.submission: the owner's only if every
  input of the run is. Agent-written inputs record the writing turn's origin: subagent
  tasks and one-shot prompts, team messages, reports (answerOrigin), peer messages.
  No peer origin any more.
- Subagents and one-shot agents get their caller's tools (default all, tools narrows),
  except scope main; with codemode the script-only tools; subagents get team. One-shot
  agents keep codemode and agent. A send takes away what the caller can no longer give.

// Code mode's one-shot `agent` tool, contributed unconditionally. Only scripts can call it (`callers: ["tools"]`), so
// without code mode nothing reaches it, and its prompt section renders only while a conversation can call both
// `codemode` and `agent`. Code mode stays independently removable: no import of its plugin. Its conversations are listed
// with the subagents (one-shot entries of their document), which is where their sidebar metadata and read-only rule live.
