Under the hood

Several new internal telemetry event names added; the old model_catalog_flag_rows event removed

What

The list of recognized telemetry event names gained several new entries: upgrade_relay_fork_direct, refusal_same_model_retry, rc_repl_fork_conversation, mcp_serve_file_call, and publish_settling. The model_catalog_flag_rows event was removed.

Why

These are internal telemetry changes with no direct user-facing effect, though the new names hint at tracking for things like relay-based upgrades, same-model refusal retries, REPL conversation forking, MCP file-serving calls, and publish settling.
