Continue work from #1525 and #1601, vendoring Click.
Note: this PR is best reviewed commit-by-commit. I've intentionally created the commits to be self-contained and tests should past (excl coverage) after each commit. I've refrained from doing additional unnecessary edits/cleanup so that the diff would be minimal in this PR.
At several places in Typer's codebase, we override/subclass Click's behaviour. This PR simplifies the code in these cases, as we don't need to keep legacy Click code around anymore.
0% vibe-coded, 100% manually-executed refactor to (try and) ensure high quality & reduce unexpected errors.
