fix(claw): warn if gateway is running before migrating bot tokens

When 'hermes claw migrate' copies Telegram/Discord/Slack bot tokens from
OpenClaw while the Hermes gateway is already polling with those same tokens,
the platforms conflict (e.g. Telegram 409). Add a pre-flight check that reads
gateway_state.json via get_running_pid() + read_runtime_status(), warns the
user, and lets them cancel or continue.

Also improve the Telegram polling conflict error message to mention OpenClaw
as a common cause and give the 'hermes start' restart command.
