Drop NickServ identification

Not registering clod with NickServ, so remove the IDENTIFY-on-connect code,
the nickserv_password_file setting and its .gitignore entry. The periodic
attempt to reclaim clod from clod_ stays.

 A small MCP server that gives Claude Code an IRC connection.
 
 - Connects to `irc.rizon.net:6697` over TLS as `clod`. If that nick is taken it uses `clod_` and tries to switch back every `nick_retry_seconds` (default 180)
-- Identifies to NickServ whenever it holds `clod`, using the password in `nickserv_password.txt` (gitignored, set by `nickserv_password_file`)
 - Answers server PINGs, sends its own keepalive PING, and reconnects automatically
 - Can only join channels listed in `allowed_channels` in `config.json` (re-read on every call, so edits apply right away)
 - Keeps a rolling buffer of recent messages per joined channel (`buffer_size`, default 200)
