When the main provider is the Codex app-server runtime (api_mode
codex_app_server), the gateway showed no verbose 'running X' tool-progress
breadcrumbs on Telegram while every other provider did. The app-server
session processes item/started notifications (command execution, file
changes, MCP/dynamic tool calls) but never surfaced them as Hermes
tool-progress events — the session was constructed without an on_event
hook, so the agent's tool_progress_callback was never invoked on this
route.
Add _codex_note_to_tool_progress() mapping item/started → (tool_name,
preview, args) for commandExecution / fileChange / mcpToolCall /
dynamicToolCall, and wire an on_event hook into CodexAppServerSession that
forwards mapped events to agent.tool_progress_callback('tool.started',
...) — the same signature the chat_completions path uses (tool_executor.py).
Non-tool items (agentMessage/reasoning) and non-item/started methods map
to None and are ignored.
