The Go generator previously emitted a `// SKIPPED` stub for any proc with a
struct, sequence or optional parameter, leaving Echo/Complex/Schedule
uncallable. Now that the native ABI carries those as flat C-POD structs, the Go
side can marshal them: emit an idiomatic Go struct per {.ffi.} type plus a
`toC()` that builds the matching `C.<Type>` (C.CString for strings, a C array
for seqs, present-flags for options, recursively for nested structs) and
returns cleanup funcs run via defer once the call returns. The native path
deep-copies every argument, so releasing the C buffers immediately is safe.
The C bridge already accepted struct-by-value params via the pass-through type
mapping; only the Go-side conversion and the `allSupported` gate needed work.
Bare seq/Option *top-level* params (not wrapped in a struct) remain skipped, as
the native ABI does not expose them either.
The generated package is now self-contained: the native `<lib>.h` is emitted
beside the `.go`, and the cgo directives use ${SRCDIR} so the header and the
staged library resolve without extra env vars. genbindings_go runs gofmt to
finalize column alignment.
