v1.3.0

Fixed

• Publishing a prompt edit could strip every tool from a live agent. A
  revision stores only the tool ids it is sent, and
  GET /client/agents/{slug}/revisions/{id} returns none, so a body rebuilt
  from the revision read unbound the transfer and hang-up tools. The agent
  then read transfer_to_human_agent{} aloud instead of transferring and
  could not hang up. scripts/ingfah_api.py now reads the agent before
  POST /client/agents/{slug}/revisions and refuses a body that omits
  phone_tools or ai_plugin_function_ids, drops an id the published agent
  uses, or has a flow state naming a tool that is not bound.
  --allow-tool-drop overrides it when removing a tool is the intended
  change.

Added

• references/agents-and-teams.md: "Carry the tools into every revision",
  covering where the ids are read from, the preview and post-publish checks, and
  publishing by id when others edit the same agent.
• references/troubleshooting.md: the "reads a tool name aloud / promises a
  transfer that never happens / repeats its goodbye" complaint, in check order
  (bindings, the call's tool messages, then the prompt).
• references/prompt-authoring.md: "Tools in the prompt" (silent transfers,
  never quote a forbidden output, keep the tool description and prompt
  consistent), the end_call_keyword tool as a third requirement for
  hanging up, and two pre-publish checks.
• references/tools.md: a tool is callable only while bound, and a tool's
  description is part of every turn.
