feat: relax typer version

[jackwalkerlabs]

Description

Relax the CLI extra's Typer upper bound from <=0.21.1 to <1 and refresh the lockfile to Typer 0.27.0. Since Typer 0.26 vendors Click, select the matching exception implementation when rendering startup validation errors while retaining the external Click fallback for older supported Typer versions. This prevents missing-option rendering from crashing on newer Typer releases.

Fixes #2969
