refactor: Simplify glob patterns in pyproject.toml

Simplify package-data wildcards from redundant patterns to cleaner syntax:
- "www/**/*" → "www/**"
- "templates/**/*" → "templates/**"
- "api-examples/**/*" → "api-examples/**"

The `**` glob pattern already matches all files and subdirectories
recursively, making the `/*` suffix redundant.

Verified that the wheel still:
- Includes 662 www/templates files
- Excludes all api-examples files
- Maintains same 3.6MB size
