- Fix handle class member functions: remove incorrect shm:: prefix
- h.acquire() not h.shm::acquire()
- h.release() not h.shm::release()
- h.sub_ref() not h.shm::sub_ref()
- Keep shm:: prefix for namespace-level global functions:
- shm::acquire(), shm::release(id), shm::get_mem()
- shm::remove(), shm::get_ref(id), shm::sub_ref(id)
- Fix comments to use correct terminology
- Resolves: 'shm::acquire is not a class member' compilation errors
- Remove 'using namespace ipc::shm;' to avoid id_t conflict with system id_t
- Add explicit shm:: namespace prefix to all shm types and functions
- Apply to: id_t, handle, acquire, get_mem, release, remove, get_ref, sub_ref
- Apply to: create and open constants
- Fix comments to avoid incorrect namespace references
- Resolves compilation error: 'reference to id_t is ambiguous'
