//! oakplugin C ABI bridge: direct Rust calls into the `oakplugin` crate.
//!
//! Single-lib unification (see `docs/zh/plans/riir/single-lib.md`): every
//! call below is a compile-time Rust call into `oakplugin`'s `ffi` (the
//! `#[no_mangle]` exports stay in the dylib for the external C ABI;
//! internal callers bypass them). Handles cross as the shared
//! [`crate::handle::CHandle`]. Exceptions that keep an `extern "C"`
//! declaration (resolved at link time against the sibling crate in the
//! same dylib) are the host `oakcore_*` symbols and the encoding-params
//! C ABI POD crossings (the facade keeps its own POD mirrors there).
