Repoint bread-theme and bread-utils at git.breadway.dev tag v0.7.1
(no github.com). bread-screenshots is not on that tag yet, so rev-pin
it instead of tracking branch=main.
Replace the homegrown PID-file toggle with bread-utils::singleton so
the launcher still dismisses on a second keybind without the TOCTOU
window. Screenshot mode still skips the lock.
README now documents the fixed BOS dark fallback (not Catppuccin
Mocha). Drop the unused GitHub Actions release workflow; Forgejo is
canonical. CONTRIBUTING already documents single-trunk.
