leftibot 64a823c630 Address review: expose strongly-typed operators for strong typedefs
Register forwarding binary operators at typedef creation time via a
custom Proxy_Function_Base subclass (Strong_Typedef_Binary_Op). Each
operator unwraps __value from both operands, dispatches on the
underlying types, and re-wraps arithmetic results in the typedef.
Comparison operators return the raw bool.

- Arithmetic: +, -, *, /, % → Meters + Meters -> Meters
- Comparison: <, >, <=, >=, ==, != → Meters < Meters -> bool
- Operators that don't exist on the base type error at call time
  (e.g. StrongString * StrongString -> error)
- Users can extend typedefs with their own operations using
  to_underlying() for unwrapping

Tests cover int-based arithmetic, string-based concatenation, string
multiplication error, comparison ops, type safety of results, and
user-defined operator extensions.

Requested by @lefticus in PR #680 review.
