fix(core): Use AND logic for multi-term package search

Changed the search logic from OR (`.any`) to AND (`.all`) when matching multiple search terms. This significantly improves search precision, as queries like "text editor" will now only return packages matching both terms instead of returning every text-related OR editor-related package.
