Add nim-bindings/tests/test_all_endpoints.nim which imports bindings
directly and calls every FFI proc, forcing the linker to include all
symbols. This catches link-time and runtime issues that the pingpong
example missed because unused symbols were optimised out.
Running the new test revealed an ABI mismatch in installation_name:
the Rust function used an explicit out-parameter but ReprCString has
only flat fields, so Nim emits it as a C return value.
CI now runs nimble test next to nimble pingpong.
* chore(nim-bindings): replace dynlib dlopen with plain importc
The dynlib pragma hard-coded a library path and resolved it via dlopen() at
runtime, preventing static linking and forcing a specific load-time path.
Using bare {.importc.} lets consumers choose: link liblibchat dynamically
at link time (--passL:-llibchat) or link it statically into their binary.
* Rust -> Nim ABI (#62)
* Use correct build hook
* force sret like return from rust code for nim compatibility
* Fix target mismatch
* Update usages
* ci: add nim-bindings-test
* fix(nim-bindings): fix ABI mismatch in destroy_* FFI functions and add defer-based cleanup
Nim's C backend silently transforms large struct parameters (>16 bytes) into
pointer parameters when calling importc functions. The destroy_* functions were
declared taking T by value in Rust, but Nim always passed &T — causing Rust to
read garbage from the stack on x86-64 (SIGILL on CI) while accidentally working
on ARM64 macOS due to that ABI coincidentally also using pointers for large structs.
Fix by changing all destroy_* functions to take &mut T and using drop_in_place,
which is the correct idiom for dropping a value through a pointer.
On the Nim side, replace scattered manual destroy calls with defer, which
guarantees cleanup on all exit paths and prevents use-after-destroy bugs.
