Variants-CIT

The current 26.1 branch seems to be compatible with the upcoming MC 26.2. I've marked it as such, but thread carefully.

• Fixed a compat issue with Iris Shaders, causing sanitize_auto and the custom_name module to yield different results from usual.
• Fixed hyphens '-' being incorrectly removed by most flavours of sanitizations.
• Fixed crash when using expect and nbtPath together.
• Fixed custom trident displaying incorrectly on shelves. (MC 1.21.9+)
• Added assetGen presets: item_model/spear, item_model/player_head, item_model/handheld_rod
