Prefect 3.4.24 requires typer>=0.16.0 to work with click 8.2+. The current constraint (typer>=0.12.0) allows dependency solvers to pick typer 0.12.5, which fails with click 8.3.0: TypeError: Secondary flag is not valid for non-boolean flag. This was discovered while fixing the conda-forge feedstock, where the conda solver was picking typer 0.12.5. Our Docker builds work because uv.lock pins to exactly 0.16.0. Tested combinations: - typer 0.12.5 + click 8.3.0: fails - typer 0.15.0 + click 8.3.0: fails (different error) - typer 0.16.0 + click 8.3.0: works Removed !=0.12.2 exclusion as it's now redundant.

closes #19259
this PR updates the typer minimum from
>=0.12.0to>=0.16.0to prevent dependency solvers from picking incompatible combinations with click 8.2+.details
background
while fixing the conda-forge feedstock for prefect 3.4.24, we discovered that the conda solver was picking typer 0.12.5 (the minimum allowed by our constraint), which fails with click 8.3.0:
our Docker builds work fine because uv.lock pins to exactly typer 0.16.0.
testing
tested with fresh environments and prefect 3.4.24:
