FEATURE: core support for tabbed interface inside markdown
This is useful for AI features and documentation. Adds support for: ``` [tabs] [tab="tab name"] content **here** [/tab] [tab="tab2 name"] other content **here** [/tab] [/tabs] ``` Optionally you can select the default tab using: ``` [tabs] [tab="tab name"] content **here** [/tab] [tab="tab2 name" selected] other content **here** [/tab] [/tabs] ```
