Description

Fixes decodeQueryFilters to properly handle parentheses and maintain correct AND/OR precedence when parsing filter queries.

Additional context

• Fix decodeQueryFilters to properly split AND segments before processing OR
• Remove outer parentheses from segments before parsing
• Handle OR conditions within AND segments correctly
• Resolve issue where parentheses were included in split results

Fixes parsing of queries like:

• (api:123) AND (status:200) → ["api:123", "status:200"]
• (api:123) AND (status:200 OR status:429) → ["api:123", "status:200", "status:429"]
