AtlasSpigot 26.2 - v2 (source brand fix)

Second release. Change from v1 (atlasspigot-26.2):

• Real source-level brand fix: CraftServer.getName() now reads the same configurable brand used by getServerModName()/BrandPayload (the actual client-facing F3 brand), instead of Leaf's hardcoded build-info name. This fixes the console startup banner, Bukkit.getName() (plugin compatibility checks), and crash reports - all previously still said "Leaf" despite config-level rebranding.

See source-patches/craftserver-brand-fix.diff in the repo for the exact change.

Going forward, every change gets its own release instead of updating an existing one.
