This pull request introduces several improvements to the NX AI FastAPI application, focusing on enhancing the product seeding process, adding full-text search capabilities, updating API metadata, and expanding test coverage. The most important changes are grouped below:

Database and Seeding Enhancements:

• The product seeding process now adds a search_vector tsvector column to the product table, populates it using relevant fields (such as title, Pack_Description, and Hierarchy1-3), and creates a GIN index to enable fast full-text search.
• The seed data CSV path was updated to point to data/seed.csv for improved organization.

API Improvements:

• The root endpoint metadata was updated with a new title and now includes a hierarchical structure for the products endpoint, listing its /seed child route.

Versioning:

• The application version was bumped from 1.0.9 to 1.1.0 to reflect these enhancements.

Testing:

• Added a new test to verify that the /products endpoint returns a list (even if empty) and includes the expected response structure.Bump package version to 1.1.0, move product CSVs into app/api/products/data and update seed path. Extend products seeding to add a search_vector tsvector column, populate it from title/Pack_Description/Hierarchy fields, and create a GIN index for full-text search. Update root endpoint metadata/title and expose a products/seed child link. Minor cleanup in main.py and add a test to assert /products returns a list structure.
