refactor: drop internal bridge/ffi layers; exporter family lands

Browse Source 
Single-lib cleanup: the per-crate src/bridge/ and src/ffi.rs layers are
gone (oakundo/oakcommon/oaknode/oaktimeline/oakcodec/oakaudio/
oakrender/oaktask/oakplugin/oakstorage); cross-crate calls are plain
Rust, CHandle marshalling shrinks to the oakengine boundary, and tests
call the Rust APIs directly (pure C-ABI wrapper tests removed where
the domain layer already covers the behavior).

exporter.h family implemented: oakengine_export_render (CLI contract),
oakengine_export_render_with_params (was a stub), last_error and
progress callback; synchronous path reuses task_create_export +
start_sync. Fixes on the way: oaktask video ticket self-deadlock,
audio params dropped on the export path, codec encoder AAC slicing and
H.264 time base. Real-mp4 tests cover both entry points, progress and
the illegal-argument matrix.

Also: oakstorage session maps null project handles to None (version-
info path), configstore test double literal 3.14 -> 3.15 (clippy PI
lint), oakaudio output callback scratch buffer + env-aware P1 test,
cli media round-trip test uses a generated 16-frame clip (no more
minute-long debug runs).

//! oakcommon C ABI bridge: direct Rust calls into the `oakcommon` crate.
//!
//! Single-lib unification (see `docs/zh/plans/riir/single-lib.md`): every
//! call below is a compile-time Rust call into `oakcommon`'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).

//! Only functions the module crates actually implement are declared here;
//! engine functions whose backing is still C++-only are facade stubs (see
//! the area modules) and never reach this module.

//! `oakcore_rational_*` live in the C++ liboakcore (only linked in the
//! real build), so cargo tests define minimal in-memory mocks — the

//! Integration tests for the common family (`src/common.rs` over
//! `engine/include/oakengine/{config,videoparams}.h`).
//!
//! Every exported function is exercised on a legal path with the result
//! asserted, plus the illegal-input matrix the engine must survive (NULL
//! pointers, empty handles, out-of-range indexes, zero/negative sizes,
//! garbage enums). All behavior is real: the facade calls into the real
//! oakcommon store and videoparams domain.
//!
//! The oakcommon config store is a process-wide singleton backed by
//! `config.ini` (honoring the `OAK_CONFIG_DIR` override), so every test
//! that touches config is serialized under [`CONFIG_LOCK`] and redirects
//! the file into a fresh temp dir. The videoparams tables are immutable
//! statics and the params handles are per-test objects, so those tests
//! run in parallel.
// The whole family is called through uniform `unsafe {}` blocks (matching
// the other test binaries), so extern functions that happen to be safe
// (e.g. `oakengine_config_load`) otherwise trip `unused_unsafe`.

//! Integration tests for the **exporter family** (`src/codec.rs`,
//! "Exporter family"; module contract
//! `engine/include/oakengine/exporter.h`).
//!
//! Coverage rules (see the family test charter):
//! 1. no mocks — every call goes through the real facade into the real
//! module crates (the only stubs are the host-provided `oakcore_*`
//! symbols in `tests/common`); the output file is a REAL mp4 written
//! by the statically linked FFmpeg (oakcodec encoder), asserted by
//! its `ftyp` box;
//! 2. every exporter-family export is exercised on a legal path with the
//! result asserted;
//! 3. illegal inputs (NULL seq/path, negative ranges, unknown codecs)
//! always yield a negative error code — never a crash;
//! 4. the progress callback receives at least one update during a run,
//! with the installed userdata.
//!
//! ## Serialization
//!
//! The tests assemble projects and run export tasks, both of which touch
//! process-wide state (the undo stack cleared by `oakengine_project_new`,
//! the global task manager), so every test takes a shared [`SERIAL`] mutex
//! (the same pattern as `it_task`).

//! Integration tests for the plugin family: the facade exports
//! `oakengine_plugin_*` (src/plugin.rs; module C contract
//! `include/plugin/{host,instance,error}.h`), exercised end to end
//! against the REAL `oakplugin` crate — no mocks anywhere.
//!
//! `oakengine_plugin_load_plugins` drives the real OFX host scan
//! (dlopen of real plugin bundles); the family's only destroy surface
//! lives in the backend module (`oakplugin_instance_create/free`), which
//! is verified here against the module's debug alive counter
//! (`oakplugin_debug_alive_count`, the leak assertion for this family).
//! The two provider setters are pure facade state (module 00 analogues of
//! the C++ capi statics): their result IS the return code, asserted below.
//!
//! The host singleton is process-global and only internally locked, so
//! every test that touches it serializes on [`with_host`] (same
//! convention as the module crate's own tests).
//!
//! The end-to-end bundle test needs the minimal test plugin that the
//! oakplugin crate's build.rs compiles (cbits/oak_test_plugin.c). When
//! it is unavailable the test prints SKIP and returns (never fails).

//! Integration tests for the undo family (`engine/include/oakengine/undo.h`,
//! implemented by `src/undo.rs` on top of the real oakundo module crate) —
//! the "real behavior, end to end" complement to the smoke tests in
//! `tests/undo.rs`. No mocks: every call goes through the facade exports
//! into the real oakundo crate.
//!
//! The facade owns a process-wide undo stack and a single open undo group
//! (the module 00 analogue of `EngineCore::undo_stack()` / `g_undo_group`),
//! so every stack- and group-mutating assertion lives in ONE serialized
//! test function ([`undo_stack_integration`]). The command-lifecycle tests
//! only touch local state and run in parallel.
//!
//! Coverage: all 23 `oakengine_undo_*` exports are called on a legal path
//! with asserted results, plus the illegal-input matrix (NULL pointers,
//! empty `CHandle::null()` boxes, out-of-range rows, zero/negative buffer
//! sizes) and the free/destroy contracts. No function in this family needs
//! GPU/app state. The regression tests at the bottom ([`null_name_push_repro`],
//! [`null_name_group_repro`], [`group_abort_undoes_children_repro`]) lock
//! three fixed facade bugs: a NULL/empty label to `oakengine_undo_push` /
//! the group-end path used to hand the module a dangling
//! `String::new().as_ptr()` (0x1) and SIGSEGV, and
//! `oakengine_undo_group_abort` used to leave its executed children
//! un-undone.

//! The render worker — the Rust port of `engine/src/capi/worker.cpp`,
//! owned by the oakengine facade and exported through the frozen
//! `oakengine_worker_*` C ABI (`engine/include/oakengine/worker.h`); the
//! `oak-worker` binary is a pure C-ABI consumer that links the built
//! `liboakengine` dylib.
//!
//! Like the C++ side, this is where the worker's whole runtime lives:
//!
//! - **Backend selection.** [`create_renderer`] initializes the render
//! backend through the oakrender module C ABI
//! (`oakrender_display_renderer_create_dynamic` + `_init`), falling
//! back to the direct OpenGL renderer exactly like the C++
//! `create_renderer()` chain. The worker executable itself never
//! touches a renderer — it is a thin shell calling
//! [`oakengine_worker_main`].

//! backend through the oakrender crate's direct Rust API
//! ([`oakrender::backend::DisplayRenderer`]), falling back to the
//! direct OpenGL renderer exactly like the C++ `create_renderer()`
//! chain.
//! - **The session.** [`WorkerSession`] holds the renderer, the
//! shared-memory frame-slot pools ([`crate::ipc::FrameSlotPool`]) and
//! the shutdown flag, and answers one NDJSON control message at a time.
//! - **The main loop.** [`worker_main`] (and its C ABI wrapper
//! [`oakengine_worker_main`]) creates the session, loads the runtime
//! config, writes the startup handshake, and serves the stdin/stdout
//! NDJSON loop until a `shutdown` message or EOF.
//! - **The main loop.** [`worker_main`] creates the session, loads the
//! runtime config, writes the startup handshake, and serves the
//! stdin/stdout NDJSON loop until a `shutdown` message or EOF.
//!
//! The control-plane protocol is the same NDJSON the C++ worker speaks
//! (`engine/render/ipc/ipcmessage.cpp`): one compact JSON object per line,
//! `"type"`-dispatched, with `handshake` carrying the shared-memory
//! geometry the worker attaches to via the real [`crate::ipc`] transport.
