okhp3-notion-identity-resolution

Dependency-loaded by other okhp3-notion-* skills. Resolves any Notion reference format (full URL, notion.site URL, bare UUID with or without dashes, collection:// data-source URL, view:// saved-view URL, discussion:// comment-thread URL, or a plain page/database title) to the correct entity type and ID, and disambiguates database versus data source versus page versus block. Not intended to be selected directly from a user prompt; always loaded by okhp3-notion-core or a sibling that needs an ID resolved before it can act.
