fix: remove parentheses and curly braces from FTS5 search queries

[Haitham-ghaida]

Problem

FTS5 search fails with a syntax error when searching for strings containing parentheses () or curly braces {}, as these have special meaning in FTS5 query syntax.

For example, this search fails with an error:

act = db.search('market for sawnwood, beam, softwood, dried (u=10%), planed')

OperationalError: fts5: syntax error near "dried"

This affects searches for product specifications like "dried (u=10%)"

Solution

Modified the search query to strip parentheses and curly braces before passing to FTS5. This allows the search to work with these special characters while maintaining the search functionality.

Testing

• Added test case verifying search works with parentheses
• Ran full test suite locally, all tests pass
