chore: bump epoch on moongreet-git and sweet-cursors-git

Local AUR/older builds outsort the registry versions on pacman vercmp:

- sweet-cursors-git: paru-built r445 (Gigas002/Sweet#cursors) > registry
  r1 (our snapshot fork). Snapshot stays frozen by design.
- moongreet-git: pre-rollback 0.10.0 > current 0.8.6 (upstream tag
  history continued at 0.8.4–0.8.6 on top of an earlier 0.10.0 line).

epoch=1 on both, pkgrel bumped to retrigger CI. Also extends .gitignore
to cover the remaining makepkg bare-clone dirs (moongreet, moonlock,
moonset, sshfs_connect) that weren't listed before.
