Silence GIMP 3.x i18n warnings on plugin load

[maorcc]

Problem

On GIMP 3.x startup, for every registered procedure that doesn't explicitly override set_i18n(), GIMP logs three warning lines:

[plug-in-mcp-server] The catalog directory does not exist: ~/.config/GIMP/3.2/plug-ins/gimp-mcp-plugin/locale
[plug-in-mcp-server] Override method set_i18n() for the plug-in to customize or disable localization.
[plug-in-mcp-server] Localization disabled

The plugin registers three procedures (plug-in-mcp-server, plug-in-mcp-check, plug-in-mcp-restart), so that's 9 noise lines on every launch.

Fix

Override do_set_i18n on MCPPlugin to return False. No behavior change — localization was already disabled, this just tells GIMP it's intentional.

Test plan

• ruff check clean
• Restart GIMP after install, confirm the 9 lines are gone

Summary by CodeRabbit

• Updates
  • Modified plugin internationalization behavior to prevent GIMP from automatically translating plugin procedures, providing explicit control over translation handling.
