Changes

Implement tags for holdable armor

Will be used for shields shortly, and eventually staffs
Holdable armor triggers most modifier hooks as if it were worn armor, but only triggers counterattack when blocking (making counterattack shield exclusive)

Move logic that clears fast item use into interaction handler

Ensures we do not need to implement a modifier every time we want that fix. Also will be needed for a future API improvement
Also reduce the timer on client equipment change watcher to remove stutter when the hook triggers

Implement active modifier system

Improved version of the interaction modifier hooks, instead of marking in persistent data and then looking for your marker, we mark then only call the marked modifier

Migrate tasty to the improved logic

Will prevent eating daggers wrongly from preventing dagger stacking

Implement blocking modifier and shield stats

TODO: item model predicate/transforms for blocking

Add option for tools to have arbitrary modules registered as part of the definition

For 1.19, will move AOE logic, harvest logic, and melee logic to this system. Will be useful for addons that wish to make up their own additional JSON settings, and just encourage me to do less hardcoding of stuff in classes

Implement tool definition module for changng interactions

By default, most tools allow any interaction modifier to act
Slimestaffs support both left and right click interaction, they use a worktable recipe to choose which interaction on a per modifier basis
Shields support left click interaction, and also have a single right click modifier for blocking. They use a more restricted version of the module

Implement modifiable staff item

Base class for shields, staffs, and potentially slimeslings

Fix stutter when blocking or eating a tool

Turns out you want to set the active hand after changing the item NBT

Implement travelers shield

Travelers shields are lightweight shields, allowing you to dash while shielding. They only block a max of 10 damage, which is sufficient against most attacks
Plate shield will come in a later commit

Add tool blocking predicates to all melee weapons that can receive the blocking modifier

Well, will be able to receive it. Need to decide on a recipe still, and arrange a couple of things for daggers

Implement slime staffs

Slime staffs are items that do nothing, but can be modified with any interaction modifier. They are set apart from other tools by starting with two ability slots, and in some cases defense slots.
In the future, they will get some unique spell modifiers.

Tweak protection modifiers

Protection is now 5% per level, but is capped at one level per piece
Conditional protection is now 10% per level
Goal is buffing armor to be closer to vanilla without making it too strong once you have dragon heads

Add recipe for blocking modifier
