Change community_rating from DECIMAL(3,1) to DOUBLE PRECISION to:
- Eliminate awkward pgtype.Numeric conversion in Go code
- Enable direct pgtype.Float8 mapping from ComicInfo.xml float64
- Simplify code by matching natural types (XML float64 → PostgreSQL DOUBLE PRECISION → Go pgtype.Float8)
- Remove need for string formatting and Scan() method calls
The floating-point precision error (< 0.00001%) is negligible for 0-10 rating scale.
This simplifies Phase 4 implementation significantly.
Column comment updated to reflect DOUBLE PRECISION type.
