Update project metadata for octoenergy fork

Update pyproject.toml with octoenergy-specific metadata:
- Change version from 1.2.4 to 1.0.0 (fresh start for fork)
- Update author to Mattia Baldari <[email protected]>
- Update homepage URL to https://github.com/octoenergy/graphql-schema-diff/

This distinguishes the fork from the original Ambro17/graphql-schema-diff
repository and reflects octoenergy's ownership and maintenance.
