[INFRA] Set up default rulesets for default and release branches

[asf-gitbox-commits]

This Pull Request enables the repository to conform with the "sane default security settings" of the Apache Software Foundation by configuring a default branch ruleset that protects the default branch and any release branches.

Note that ~DEFAULT_BRANCH is a GitHub symbolic link to the current default branch (HEAD) of the repository and does not need changing.
If the managing project does not wish to set up these defaults, please close this Pull Request. Alternatively, the project may merge this Pull Request to apply the changes immediately.

If no action is taken, this Pull Request will be automatically merged by the Apache Infrastructure team on 2026-06-14 (30 days from now).

For any further information, please reach us on Slack or at: users@infra.apache.org

I've reached out to Infra and asked for our current rules. I'll create a separate PR to add these rules once they provide them.

Reviewed on behalf of the Grails PMC and pushed an update to this ruleset.

What changed (latest commit on this PR): replaced the generic release/* and rel/* include patterns with *.x, the naming convention Grails uses for maintenance/version branches (e.g. 7.0.x, 8.0.x). The original patterns matched no branches in this repository, so version branches would have been left unprotected.

Resulting protected branches:

• ~DEFAULT_BRANCH (7.0.x)
• *.x — all Grails maintenance/version branches

Settings (unchanged from the infra template):

• restrict_deletion: true
• restrict_force_push: true
• bypass_teams: [root]

Note: the *.x glob does not cross /, so automation branches such as renovate/gradle-8.x and dependabot/... are intentionally not matched (they are routinely force-pushed).
