GH-2165: Simplify VectorStore delete method to return void

sobychacko · ilayaperumalg · commit 60355160445f · 2025-02-06T15:10:47.000Z
- Change VectorStore.delete() and related implementations to return void instead of Optional&lt;Boolean&gt;
- Remove unnecessary boolean return values and success status checks across all vector store implementations
- Clean up tests by removing redundant assertions
- Implementations continue using runtime exceptions for error signaling
