Struct ParseStack 

pub struct ParseStack {
    pub recursion_depth: usize,
    pub global_iterations: usize,
}

Saved parse context. Direct port of zsh’s struct parse_stack declared in zsh/Src/zsh.h and used by parse.c:295-355 (parse_context_save / parse_context_restore). Pushes per- parse-call state so a nested parse (e.g. inside command substitution) doesn’t clobber the outer parse.

zshrs port note: zsh’s parse_stack tracks wordcode-buffer state (ecbuf, eclen, ecused, ecnpats, ecstrs, ecsoffs, ecssub, ecnfunc). zshrs builds AST trees instead so those fields collapse to a recursion_depth + global_iterations save. The lexer-side fields (incmdpos, incond, etc.) live on ZshLexer here so they get saved via the lexer’s own LexStack rather than being duplicated here.

Fields
