feat: prepare Radixor 3.0.0 with contracted tries and compiled patch commands

Introduce contracted compiled patch tries for faster lookup, make compiled
patch commands the primary runtime path, refresh stemmer benchmarks and
documentation, and restructure the documentation for 3.0.0 onboarding.

BREAKING CHANGE: Radixor 3.0.0 promotes compiled patch-command APIs and
new compiled trie artifacts as the primary runtime integration model.
