feat(phantom-ship): hara-gmail-mcp server (path 1, IMAP+SMTP) 📬

Browse source 
Adds an MCP server exposing read tools (list_inbox, search, read_email)
across three personal Gmail accounts using existing app passwords in
/etc/openclaw/. Wired into claude-channels via --mcp-config. Slated for
replacement by an OAuth2 Gmail+Calendar server in path 2.

# NixOS module for the Hara Gmail MCP server.
#
# Generates /etc/hara/gmail-accounts.json from declarative options and
# exposes the server binary through the dotfiles flake's pkgs set. Wiring
# the server into the claude-channels systemd service ExecStart is done
# by the host (phantom-ship.nix) so this module stays composable.
