fix: improve search functionality for period-prefixed terms like .rooignore

- Remove default stemmer to allow exact matches
- Remove stop word filter to allow searching for common words
- Increase search result limits from 8 to 20
- Increase search result context length from 50 to 100 characters

This should fix the issue where searching for terms like ".rooignore" or ".gitignore" returns no results.

Fixes RooCodeInc/Roo-Code#6508
