Maintenance and corrections

Added daily immutable research snapshots, coin/date filters, searchable archives, pagination, scoring version labels, reasons and risk notes. Market research is now the main experience, with claim discovery available separately. Added methodology, learning examples, operator/contact information, and market-related terms and privacy disclosures.

Retained wallet checks that require only public addresses where supported. Checks requiring project allocation details remain in Advanced and explicitly report unknown eligibility. Contract detail pages remain excluded from Search until they warrant standalone indexing. Removed advertising code from the scanner; no advertising code is added to operational feed or archive screens.
