/**
Transforms an Oniguruma AST in-place to a [Regex+](https://github.com/slevithan/regex) AST.
Assumes target ES2025, expecting the generator to down-convert to the desired JS target version.

Regex+'s syntax and behavior is a strict superset of native JavaScript, so the AST is very close
to representing native ES2025 `RegExp` but with some added features (atomic groups, possessive
quantifiers, recursion). The AST doesn't use some of Regex+'s extended features like flag x or
subroutines because they follow PCRE behavior and work somewhat differently than in Oniguruma. The
AST represents what's needed to precisely reproduce Oniguruma behavior using Regex+.
