Site configuration table
Each site defines:
- bases: hostnames (used to build a domain → site map for O(1) lookup)
- extractor: function returning { id, name } or null.
- prefix: id prefix to prevent collision in the shared "database" map
- toastUrl Prefix+Suffix: to reconstruct a link from the deleted id (deletion toast)
Design decisions:
- O(1) hashmap domain lookup to avoid testing every domain to pick the right extractor (regex overhead of handling /i etc)
- Xenforo name+id extraction was impossible with regexes; I wanted ALL of its logic in one place, extractXenForo()
