Add .kilocode/rules/protected-branches.md to document branch name
patterns that must not be created (e.g. feature-*, patch-*, fleet-v*,
rc-*) and guidance to avoid accidental creation of protected branches
enforced by GitHub. Update the cherry-pick skill to reference the new
rules and explicitly warn users not to create working branches that
match protected patterns, explaining that such branches are protected
and direct pushes will be rejected.
