docs: add manage as approved verb for multi-modal tools

Tools like ha_manage_addon (homeassistant-ai#913) and ha_manage_custom_tool (homeassistant-ai#854)
combine several operations (get/set/list/call) behind one tool. The
existing verb list had no good fit — "manage" captures this pattern.

Updated in all four locations:
- AGENTS.md naming convention + docstring verb list
- .gemini/styleguide.md naming convention + docstring verb list
