Replace all instances of percent-style string formatting with
f-strings across the rvgen codebase. This modernizes the string
formatting to use Python 3.6+ features, providing clearer and more
maintainable code while improving runtime performance.
The conversion handles all formatting cases including simple variable
substitution, multi-variable formatting, and complex format specifiers.
Dynamic width formatting is converted from "%*s" to "{var:>{width}}"
using proper alignment syntax. Template strings for generated C code
properly escape braces using double-brace syntax to produce literal
braces in the output.
F-strings provide approximately 2x performance improvement over percent
formatting and are the recommended approach in modern Python.
