The AI website editor now separates element selection from the main editing plugin, making the feature easier to maintain and reducing unnecessary background communication. This is an internal cleanup that should help future improvements without changing the user workflow.

Element selection was mixed into the main website builder plugin that builds page context and applies AI changes, which made the plugin too big to navigate.

This commit gives the "element selection" feature its own plugin to address that concern and avoid the additional Bus calls.
