OmarchybotandClaude Opus 5 7b89780810 Flag a reboot when the docker group changes (backport of #8080)
Backport of the reboot flag (PR #8080, merged to quattro as 1565919c) onto the
v4-0-1 release branch, on top of the #8056 backport it follows.

Group membership is fixed at login, so removing (or adding) the docker group
does not take effect in the running session. The existing-user migration and the
Setup > Security toggles now call omarchy-state set reboot-required, so
omarchy-update-restart prompts for the reboot that actually applies the change
and the bar shows it pending. A plain log out and back in still works.

The migration test now exercises the real removal command and omarchy-state
rather than a stub, asserting the reboot flag is set on removal and left alone
when the user is already out of the group.

Clean cherry-pick on top of the #8056 backport: all three files are
byte-identical to quattro, so merging v4-0-1 into quattro resolves without a
conflict. omarchy-state and omarchy-update-restart are unchanged on this branch
and read the same ~/.local/state/omarchy/reboot-required marker. test/shell
passes: 186 files.
