/**
 * Operand-type classification for the Jinja2 template adapter.

 * Ported from `packages/adapter-xslate/src/adapter/expr/operand.ts`. Pure
 * function over `ParsedExpr` taking an `isStringName` predicate rather than
 * reading adapter instance state.
 *
 * NOTE: like Kolon's `==`/`!=`, Jinja/Python's `==`/`!=` are value-equality
 * operators that compare strings and numbers correctly, so the Jinja
 * emitters never need to steer string comparisons onto a different operator
 * family. This helper is therefore not consumed by the Jinja lowering
 * today either — kept only as the parallel of the Xslate/Mojo adapters'
 * `expr/operand.ts` (groundwork for a future shared codegen surface).

 * `===`/`!==` always map to `==`/`!=`. Kept only as the parallel of the
