Relax uv version pin to ~=0.11.0 and document exclude-newer requirement

The exact pin ==0.11.2 was never enforced because the invalid
"7 days" value in exclude-newer caused the entire [tool.uv] section
to fail parsing on older uv versions. Relative dates in exclude-newer
require uv >= 0.11, so the pin is relaxed to ~=0.11.0 to accept any
0.11.x patch release.
