fix: dismissed (archived) patterns still surface in recall results

[CalebisGross]

Problem

After archiving a pattern via dismiss_pattern, it still appears in recall and recall_project pattern results. Either:

• The pattern query doesn't filter by state = 'active'
• Results are cached and the cache isn't invalidated on archive

Steps to Reproduce

1. Call dismiss_pattern with a pattern ID
2. Call recall with a query that would match that pattern
3. The dismissed pattern still appears

Expected

Archived patterns should not appear in any recall results.

Fixed in #324 — UpdatePattern now guards with WHERE state != 'archived' so consolidation can't overwrite a dismissed pattern back to active.
