Pin bread-theme/bread-utils to bread-ecosystem tag v0.7.2.
Subscribe from the locker and from `breadlock listen` so the command
works while unlocked; start breadlock the same way hypridle does.
Emit bread.lock.lock.done / .failed. Document loginctl lock-session
as the Super+L equivalent.
Optional GPG detach-sign of the .pkg.tar.zst when GPG_PRIVATE_KEY is
set; ISO [breadway] stays SigLevel = Never until a signed db exists.
Emit bread.lock.locked when ext-session-lock-v1 is accepted and
bread.lock.unlocked after PAM success. Fail-silent if breadd is down.
No command verbs (no pin/blur stubs). breadgreet is not on the bus.
Note that Forgejo Arch registry packages are unsigned (SigLevel=Never
on BOS) without changing the package.yml registry.
