about

nx_strconv.nx -- string <-> integer conversion utilities. Foundational for every CLI tool: parsing argv ints, formatting counts in log lines, decoding hex addresses for the debugger. Today the inline patterns scattered across runtime/ duplicate this work in 14 places (nx_objdump, nx_readelf, nx_dbg, nx_addr2line, nx_diff, nx_argv, nxc_native_wrap, ...). Centralise here so they all agree on edge cases (negative MIN_I64, leading "+", overflow detection, hex prefix tolerance).
