Library exports and callbacks passed text only as a pointer and length. profile_format 2 adds the cstring class, a NUL-terminated `const char *` (an i32 pointer in Wasm reactors), for export parameters, export results and callback parameters. Parameters are copied in and decoded as UTF-8, with U+FFFD for malformed bytes; a NULL pointer is the SC4012 host-contract trap. Results live in the result arena like string results. A result or callback argument containing U+0000 traps instead of being truncated. Closes #615 Co-authored-by: ailuoku6 <23209876+ailuoku6@users.noreply.github.com>
