This exposes the SGR parser to the C and Wasm APIs. An example is shown
in c-vt-sgr.
Compressed example:
```c
#include <assert.h>
#include <stdio.h>
#include <ghostty/vt.h>
int main() {
// Create parser
GhosttySgrParser parser;
assert(ghostty_sgr_new(NULL, &parser) == GHOSTTY_SUCCESS);
// Parse: ESC[1;31m (bold + red foreground)
uint16_t params[] = {1, 31};
assert(ghostty_sgr_set_params(parser, params, NULL, 2) == GHOSTTY_SUCCESS);
printf("Parsing: ESC[1;31m\n\n");
// Iterate through attributes
GhosttySgrAttribute attr;
while (ghostty_sgr_next(parser, &attr)) {
switch (attr.tag) {
case GHOSTTY_SGR_ATTR_BOLD:
printf("✓ Bold enabled\n");
break;
case GHOSTTY_SGR_ATTR_FG_8:
printf("✓ Foreground color: %d (red)\n", attr.value.fg_8);
break;
default:
break;
}
}
ghostty_sgr_free(parser);
return 0;
}
```
**AI disclosure:** Amp wrote most of the C headers, but I verified it
all. https://ampcode.com/threads/T-d9f145cb-e6ef-48a8-ad63-e5fc85c0d43e
