Docs sections were previously hard-coded to the seed values (Getting started / Guides / Reference) — there was no admin UI to add or rename them.

You can now manage your docs taxonomy entirely from the docs admin page:

• Add any header you want — Cookbook, FAQ, API reference, Tutorials, Migration guides, …
• Rename existing sections inline (header + slug)
• Reorder with up/down arrows (position swap)
• Delete safely — pages are orphaned (section_id = null) rather than dropped, so it's reversible

Behind the scenes:

• New server actions: createDocSectionAction, updateDocSectionAction, moveDocSectionAction, deleteDocSectionAction
• Slug uniqueness via the existing (project_id, slug) constraint, with a friendly error when collisions happen
• Confirmation prompt warns when a delete will orphan pages
