feat: add function to delete many records from vector db

[NorbertKlockiewicz]

Add bulk delete functionality to OPSQLiteVectorStore

This PR introduces a deleteMany method to the OPSQLiteVectorStore class that allows for efficient bulk deletion of vector records based on a predicate function.

Key changes:

• Added deleteMany(predicate) method in packages/op-sqlite/src/wrappers/op-sqlite.ts:114-143
• Method accepts a predicate function to filter which records to delete
• Efficiently batches deletions using SQL IN clause with parameterized queries
• Safely handles empty result sets (no unnecessary DELETE operations)

Functionality:

• Retrieves all vectors from the database
• Applies the provided predicate function to each SearchResult
• Collects IDs of records that match the predicate
• Performs a single bulk DELETE operation for all matching records
