refactor: remove /model slash command from CLI and gateway (#3080)

Browse Source 
The /model command is removed from both the interactive CLI and
messenger gateway (Telegram/Discord/Slack/WhatsApp). Users can
still change models via 'hermes model' CLI subcommand or by
editing config.yaml directly.

Removed:
- CommandDef entry from COMMAND_REGISTRY
- CLI process_command() handler and model autocomplete logic
- Gateway _handle_model_command() and dispatch
- SlashCommandCompleter model_completer_provider parameter
- Two-stage Tab completion and ghost text for /model
- All /model-specific tests

Unaffected:
- /provider command (read-only, shows current model + providers)
- ACP adapter _cmd_model (separate system for VS Code/Zed/JetBrains)
- model_switch.py module (used by ACP)
- 'hermes model' CLI subcommand
