Under the hood
Internal hook lookups switched from raw map access to dedicated accessor methods
What
Internally, code that checks whether a hook applies (for example, hooks that run when a UI component renders) used to look values up directly in maps using .has(...) and .get(...). It now goes through dedicated methods, r.hooks(...) and r.matcherFor(...), instead.
Why
This is an internal code cleanup with no expected effect on how hooks behave; it changes how the lookup is implemented, not what it returns.
