[BUG] pyproject.toml says python>=3.10 but relies on fastcore 2.0.4 which is >=3.11

**Expected behavior**
The pyproject.toml say supports python>=3.10, but fastcore>=2.0.4 is a dependency that requires python>=3.11
**Environment Information**
Please provide the following version information:
- fastlite version:
- fastcore version: 2.0.4
- fasthtml version: 0.14.6

**Confirmation**
Please confirm the following:
- [x] I have read the FAQ (https://docs.fastht.ml/explains/faq.html)
- [x] I have provided a minimal reproducible example
- [x] I have included the versions of fastlite, fastcore, and fasthtml
- [x] I understand that this is a volunteer open source project with no commercial support.

Open pyproject.toml and compare the declared Python requirement with the fastcore 2.0.4 dependency requirement. Decide how the package metadata should align those constraints, then verify that dependency installation and the supported Python versions remain consistent.
