Constrain click to <8.2 for typer 0.9.x compatibility

The Docker build runs `pip install -e .`, which ignores requirements.lock and
resolves click >=8.2. typer 0.9.x is incompatible with click >=8.2 and raises
"TypeError: Secondary flag is not valid for non-boolean flag" at CLI startup,
so `docker compose up` fails on a fresh Docker install (CI is unaffected
because `rye sync` uses the lockfile).

Fixes #341
Fixes #348
