Events now mirror the native/CBOR split already in place for requests, with the
same symbol-naming convention:
- `<lib>_add_event_listener` -> NATIVE listener (typed `<T>Pod` by pointer)
- `<lib>_add_event_listener_cbor` -> CBOR listener (EventEnvelope bytes)
Framework: `FFIEventListener` gains a `native` flag; `addEventListener` a
`native` param; a new `dispatchFFIEventDual` template builds the `<T>Pod` once
for native listeners (`nimToPod`/`freePod`) and the CBOR envelope once for the
rest, fanning each out — so a single `{.ffiEvent.}` dispatch serves both kinds.
`declareLibrary` exports both registration entry points.
Generators: the bare `<lib>_add_event_listener` is the native symbol; every
CBOR consumer (C/C++/Go/Rust) now targets `<lib>_add_event_listener_cbor`. The
rename and the generator updates ship together so the bare name is never briefly
broken. Bindings regenerated.
Validated: native-event unit test (typed POD to native + CBOR to cbor listener,
orc/refc/ASAN); full unit suite; C++ e2e 19/19; Go example; existing event
tests unchanged. The per-event *typed* native callback + wildcard router (the
ergonomic consumer surface) is a follow-up.
