Crate openjd_expr 

Open Job Description expression language.

This crate implements the expression language for OpenJD templates:

• Format string parsing and resolution ({{Expr.Name}} syntax)
• EXPR extension expression evaluation (arithmetic, conditionals, functions)
• Type system, runtime values, and symbol tables
• Range expressions and path mapping

Uses ruff_python_parser for EXPR extension expression parsing. See specs/expr/parser.md for rationale.
