ci: add local pre-commit DCO hook and setup command - #9094
Conversation
Enforce the DCO sign-off locally so contributors catch a missing Signed-off-by before CI, alongside the existing black/isort/ruff formatting hooks. - .pre-commit-config.yaml: install the commit-msg hook by default (default_install_hook_types) and add a local DCO check hook. - .github/hooks/check-dco.sh: commit-msg hook that fails when the Signed-off-by line is missing. - runtests.sh: new --setup option that runs 'pre-commit install'. - CONTRIBUTING.md: document installing the hooks and the DCO check. Related to Project-MONAI#9058 and Project-MONAI#8683. Signed-off-by: R. Garcia-Dias <rafaelagd@gmail.com>

In @.github/hooks/check-dco.sh:
- Line 18: Update the sign-off pattern in check-dco.sh to accept an optional
carriage return before the line end, preserving validation of the existing
Signed-off-by format. Add a test covering a CRLF-terminated commit message to
confirm the commit-msg hook accepts valid sign-offs.
In `@runtests.sh`:
- Line 449: Update the setup completion message in the dry-run handling around
the hook installation flow so --dryrun --setup does not claim hooks were
installed; emit a dry-run-specific message or suppress the success message,
while preserving the installed confirmation for real setup execution.

I think this content should go below with the section discussing DCO and signoff, users won't know what DCO is at this point in the document.
We should also mention somewhere about setting your git global variables to use in the signoff. With git config --global --edit users should set name and email like this:
[global]
[user]
name = Eric Kerfoot
email = 17726042+ericspod@users.noreply.github.comThe no-reply email address Github assigns to each user can be seen at https://github.com/settings/emails. As I use here, it's more private to use this address rather than an actual email, and it's associated directly with your Github username.
We should also mention that VSCode can be set to automatically sign off on every commit.
- .github/hooks/check-dco.sh: accept CRLF-terminated Signed-off-by lines - runtests.sh: don't claim hooks were installed under --dryrun --setup - CONTRIBUTING.md: move DCO sign-off details out of the coding-style section, document setting git user.name/email (including GitHub's no-reply address) and VS Code's auto sign-off setting Signed-off-by: R.

Description
Enforce the DCO sign-off locally so contributors catch a missing
Signed-off-byline before CI, alongside the existing black/isort/ruff formatting hooks.The black and isort hooks already run via pre-commit (#9061), but the DCO check still only lives in the GitHub DCO app, so a missing sign-off is only discovered after pushing. This change:
.github/hooks/check-dco.sh, acommit-msghook that fails when theSigned-off-byline is missing.default_install_hook_types: [pre-commit, commit-msg]in.pre-commit-config.yamlso a plainpre-commit installwires up both stages, and registers the new local DCO hook.--setupoption toruntests.shthat runspre-commit install.CONTRIBUTING.mdto document installing the hooks and the DCO check.The black/isort -> ruff format consolidation remains tracked separately in #9066.
