1.0.2

Parallelized parsing with ColBERT and BM25 embeddings
## What's Changed

We have parallelized the parsing process and packaged the entire parsing into one sub package for parsing.So the old `create_graph_rs` Rust module has been replaced with a new app/src/parsing/ module with ColBERT/BM25 hybrid vector indexing via Qdrant for superior code search quality.

### Core Infrastructure
- New Parsing module (app/src/parsing/): Complete rewrite with tree-sitter for multi-language support, 800+ lines of tag extraction, and Python bindings via PyO3. Moved parsing queries to the new module structure.
- Qdrant Hybrid Search: Added dense (ColBERT) + sparse (BM25) vector indexing to the code graph pipeline. Non-fatal indexing failures don't block graph creation. Includes deletion handling on project cleanup.
- Qdrant configuration: Added Qdrant configuration support (host, port, gRPC port, API key, HTTPS) alongside existing Neo4j config.

### Multimodal & Conversation Improvements
- Attachment Handling: Extended conversation creation to accept attachment_ids. First-message attachments are now stored in Redis and applied retroactively if the client redirects without re-sending them.
- Document Attachments: Multimodal processing now handles both images and documents (AttachmentType.DOCUMENT), not just images.
- Agent Updates: Added update_agent endpoint to conversation controller for dynamic agent switching.
