Added

• A warmup for /spawn. spawn-command.warmup-seconds sets the delay; walking to another block or taking damage cancels it (cancel-on-move, cancel-on-damage), so /spawn is no way out of a fight. advancedspawn.bypass.warmup skips it. Default 0, instant as before.
• spawn.teleport-on-first-join: send only brand-new players to spawn, without moving everyone on every join.

Changed

• First stable release with the Folia support from 1.2-BETA, so servers on the default release update channel get it as well.

Existing servers: the new options are not added to an existing config.yml. Without them the plugin behaves as before.
