Summary

Fixes #3.

This keeps semantic index paths consistent when PUT /document updates a field that contains xText or xImage.

Changes:

• pass the updated field path into process_document() from process_update()
• thread collection_name through delete_overwritten_pc_vectors()
• build old-vector deletion prefixes as project#db#collection#doc#path

Validation

I verified the helper behavior with Pinecone/MinIO stubbed so the path logic can be checked without external services:

CREATE_VECTOR_ID= proj#db#items#doc1#description#0
CREATE_METADATA_PATH= description
UPDATE_VECTOR_ID= proj#db#items#doc1#description#0
UPDATE_METADATA_PATH= 'description'
DELETE_CALLS= [('proj', 'db', 'proj#db#items#doc1#description')]
PASS

Also ran:

python3 -m compileall -q blueprints/v0/project/db/collection/document/helper.py blueprints/v0/project/db/collection/document/services.py
