## What changed? - Split implementation of "constrained default" settings from "plain default" settings. This is more code and the diff looks complex, but the individual paths are both simpler than the mixed version. - Add conversion cache using a weak map. - Remove GlobalCachedTypedValue. - Use "raw" values for subscription dispatch deduping to avoid unnecessary conversions. - Deep copy default values when using mapstructure, to avoid problems with merging over shared default values. ## Why? - Fixes #6756 - Performance improvement for "plain default" settings (almost all of them) - Performance improvement for settings with complex converters - Remove footgun in defaults that aren't scalar values ## How did you test it? existing+new unit tests
