docs: sync from coipond/coi-wiki (binary, pre_launch, protected branches, health --fix) Mirror of coi-wiki c8a4cd8 (docs/binary-pre-launch-guard-health), flattened: [tool] binary and pre_launch, [git] protected_branches, `coi health --fix`, visudo-validated sudoers instructions, current reverse-shell detection behavior, and the large-UID subuid/subgid fix. Also renames Updating-COI.md -> Updating-Coi.md, matching coi-wiki and the existing [Updating Coi](Updating-Coi) links, which pointed at a page that didn't exist under that name here.
