Two significant commits hit submain today, closing out the static string subset for the JIT. D2.3d brings print-time string interpolation and f64 print support, and D2.3c adds compile-time literal string concatenation and content equality. The commit sequence moved our parity numbers from 215/71/0 to 222/64/0 across 286 fixtures—submain is advancing fast.

No runtime string construction here; we're passing literals and values through type-suited intrinsics and completing the statement with a `cx_print_newline`. The aim? Completely sidestep R6 by avoiding dynamic string allocation.

We diverged from the interpreter in a couple of nuanced areas: shadowed names after exiting inner blocks and handling use-before-declaration. Neither scen
