Support negative matching in queries

[luigi-agosti]

Feature

Allow users to exclude elements from matches using negative qualifiers.

Examples

• 'submit button not in header'
• 'login link, not the footer one'
• 'search box excluding sidebar'

Proposed approach

1. Parse negative qualifiers (not, excluding, except)
2. Score candidate elements against the exclusion context
3. Penalize or filter elements that match the exclusion

Use cases

• Pages with duplicate elements in different sections
• Distinguishing between header/footer/sidebar variants

I’m working on implementing negative matching support for queries. Planning to handle parsing, scoring updates, and test coverage for this feature.
