The `nc` crate and `zed --nc <socket>` flag were added in #34577 to let
the Claude Code integration spawn the running zed binary as a
netcat-style bridge between stdio and a Unix socket for its MCP server.
That integration was removed in #37120 in favor of the external
`@agentclientprotocol/claude-agent-acp` npm package, which dropped the
only caller of `--nc`. The flag, its dispatch in `main.rs`, and the `nc`
crate itself were left behind and have been unused since.
Nothing in the Zed codebase spawns `zed --nc` anymore, so remove the
flag and delete the crate. The unrelated `--askpass` netcat bridge (in
the `askpass` crate) is unaffected.
