fix: accept composed arguments, array expressions, and interval aliases - #80

📝 WalkthroughWalkthroughThe parser now accepts pipelined expressions in arrays and tuple-projection pipelines as function arguments. Interval shorthand parsing supports comparison operators and positive or negative word forms. C# syntax binding and parser corpus tests cover the new syntax. ChangesExpression syntax extensions
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to An overflowing comparison interval bound may receive a generic interval error instead of a precise numeric-literal diagnostic for the bound. This is a localized, non-blocking correctness issue, so the PR is mergeable with explicit owner follow-up and an added regression test. Sequence Diagram(s)sequenceDiagram

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Preserve the numeric-literal diagnostic for overflowing comparison bounds.
Line 252 constructs NumericLiteralSyntax outside bound-specific error handling. If I(>79228162514264337593543950336) overflows decimal, BindValue reports an interval_literal error for the full interval. Ordinary interval bounds report the failing numeric_literal and its bound span.
Catch FormatException and OverflowException around this construction. Emit a SyntaxError for numeric_literal with value's span. Add an overflow comparison-bound test.

Summary
Impact
Previously valid standalone expressions and established interval aliases can now be used in their intended nested contexts without extra parentheses or syntax errors. Authored shorthand text and source spans remain available through the typed syntax tree.
