- Add the `-d:ffiMode=native|cbor|both` strdefine (default both) with `ffiEmitNative`/`ffiEmitCbor` helpers; the C generator now emits only the selected header(s) (`<lib>.h` and/or `<lib>_cbor.h`). - Native C events: the native header documents each event's payload type (`"on_echo_fired" -> const EchoEvent *`) so consumers cast the callback's msg to the typed struct — the bare native listener already delivers it. - nimble tasks: `genbindings_c` (both), `genbindings_c_native`, `genbindings_c_cbor`. Verified: native mode emits only my_timer.h, cbor only my_timer_cbor.h, both emits both. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

// Native (zero-serialization) C ABI. Each call delivers its result to the
|
|
// callback. On RET_OK:
|
|
// - string-returning procs: (msg, len) is the raw string bytes (not
|
|
// NUL-terminated; use len).
|
|
// - struct-returning procs: msg is a pointer to the returned C struct — cast
|
|
// it to `const <Type>*` (len is sizeof). It is valid ONLY for the duration
|
|
// of the callback; copy out anything you need before returning. The library
|
|
// deep-frees it right after the callback (you free nothing).
|
|
// On RET_ERR, (msg, len) is the raw error text. A `<name>_cbor` variant of each
|
|
// proc also exists for generic/cross-language callers that prefer CBOR.
