fix(oakengine): facade bugs found by integration tests

undo:
- NULL/empty label no longer crosses to oakundo as a dangling 0x1
  pointer (push, group_begin/end) — fixed SIGSEGV
- group_abort now undoes each executed child in reverse order

task:
- create_project_import addrefs the borrowed project handle instead of
  freeing it under the async task — fixed UAF/SIGSEGV

timeline:
- toggle_enabled/delete_clips guard NULL+0 slices — fixed SIGABRT
- BlockSplitCommand halves placed correctly (oaktimeline undosplit)
- PreservingLinks / ripple remove / ripple delete-gaps commands
  self-prepare on first redo — fixes silent no-op split/ripple
- trim_clips_to targets the block containing the point, not the track
- delete_empty_tracks applies the live track removal
- ripple facades no longer free borrowed track handles still referenced
  by commands — fixed UAF

node:
- project_add_node releases the factory handle — fixes per-call leak
- inputs_from(recursive=0) matches direct feeders (BFS off-by-one)
- group passthrough id/resolve treat two-stage string length as success
- node_connect(_command) reject duplicate connects with E_STATE
- folder_add_child enforces one-folder-per-node
- value_split_to_tracks splits vector/color per component
- set_context_position/expanded establish the first entry
- node_get_flags on an empty box returns 0, not u64::MAX
- footage_borrow addrefs its wrapper — fixes double-free

render:
- renderer_create rejects invalid pixel formats (real range check)
- render_frame forwards renderer width/height to the ticket

tests: repro #[ignore]s removed, bug-behavior assertions corrected,
it_undo global-stack tests serialized with a shared lock

// (facade creates the node via `oaknode_factory_create_from_id` — owned,
// alive-counted — pushes the AddNode command that MOVES the node into the
// project graph, but never releases the factory handle). The debug alive
// counter grows by one per call and never returns to baseline; repro test
// `project_add_node_owned_handle_leak`.
// 1. `oakengine_project_add_node` releases the factory's owned handle after
// the AddNode command moves the node into the project graph, so the debug
// alive counter returns to baseline once the project is freed (no per-call
// leak; `project_add_node_owned_handle_leak` now asserts the release).
//
// 2. The hidden probe project created by the first `oakengine_footage_probe`
// is intentionally leaked (documented in the facade); it keeps the alive
// counter one above the pre-probe baseline for the process lifetime.
//
// 3. `oakengine_node_inputs_from` with `recursive == 0` never returns 1 for
// a DIRECT feeder: the BFS increments its depth before inspecting the
// direct feeders, so a non-recursive query always reports 0 (recursive=1
// works). Off-by-one in the facade BFS (src/node.rs `inputs_from`).
// 3. `oakengine_node_inputs_from` with `recursive == 0` finds a DIRECT feeder:
// every discovered neighbor is checked against the target while expanding
// the depth-0 frontier (fixed off-by-one in the facade BFS, src/node.rs
// `inputs_from`).
//
// 4. `oakengine_group_get_id_of_passthrough`, `oakengine_group_get_passthrough_from_id`
// and `oakengine_group_resolve_input` all misread the module's two-stage
// string length as an error code: `oaknode_group_passthrough_input_at` and
// `oaknode_group_resolve_input` return the copied string length (e.g. 9
// for "value_in") on success, and the facade treats any non-zero as a
// failure. Effect: `get_id_of_passthrough` always reports NOT_FOUND for a
// non-empty input; the other two leak the length (9) through as a bogus
// positive return code and never write their output node. Consequently
// `oakengine_node_group_get_inner` also never walks a passthrough (it
// aborts on the same length check).
// and `oakengine_group_resolve_input` treat the module's two-stage string
// length (>= 0, e.g. 9 for "value_in") as a SUCCESS, only negative codes as
// failures. `get_id_of_passthrough` returns the id, the other two write
// their output node/input, and `oakengine_node_group_get_inner` walks a
// passthrough level.
//
// 5. `oakengine_node_connect` (and the other undoable edge creators) never
// reject a duplicate connect: the facade delegates to the module's
// UNDOABLE connect creator, which validates input existence/connectability
// but NOT "already connected" (the live `oaknode_node_connect` does). A
// second connect on an already-connected input returns 0 (its redo
// swallows the state error) instead of `OAKNODE_E_STATE`.
// 5. `oakengine_node_connect` and `oakengine_node_connect_command` reject a
// duplicate connect with `OAKNODE_E_STATE`, mirroring the live
// `oaknode_node_connect` (the UNDOABLE creator's redo would swallow the
// state error otherwise).
//
// 6. `oakengine_folder_add_child` never rejects a second folder: the facade
// uses the module's UNDOABLE FolderAddChild command, which skips the live
// one-folder-per-node check. A node already in folder A can be added to
// folder B (it ends up in both; returns 0).
// 6. `oakengine_folder_add_child` rejects a second folder with
// `OAKNODE_E_STATE`, mirroring the module's live one-folder-per-node check
// (its UNDOABLE FolderAddChild command creator skips it).
//
// 7. `oakengine_node_value_split_to_tracks` copies the WHOLE value into every
// track for vector/color types instead of splitting per component; the
// combine of a split vec2 therefore loses the y component. The facade's
// `combine_tracks` then picks each track's f[0].
// 7. `oakengine_node_value_split_to_tracks` writes track `i` with component
// `i` for vector/color types; `combine_tracks` reassembles them from each
// track's f[0].
//
// 8. Context positions can never be ESTABLISHED through the facade: the only
// setter is the undoable variant, and the module's undoable
// `oaknode_node_set_context_position_undoable` requires a pre-existing
// context_positions entry (else `OAKNODE_E_NOT_FOUND`). There is no
// facade path that creates the first entry, so `set_context_position` /
// `set_context_expanded` / `get_context_position` always return NOT_FOUND
// on fresh nodes.
// 8. Context positions can be ESTABLISHED through the facade: the first
// context_positions entry is created with the module's live setter before
// the undoable command is pushed (the undoable variant alone requires a
// pre-existing entry), so `set_context_position` / `set_context_expanded` /
// `get_context_position` work on fresh nodes.
//
// 9. `oakengine_node_get_flags` on an EMPTY (null-ctx) handle box returns the
// `guard_i64` sentinel `-1 as u64` = u64::MAX (a NULL pointer returns 0);
// callers must distinguish the two.
// 9. `oakengine_node_get_flags` reports 0 for NULL pointers AND empty
// (null-ctx) handle boxes — the `guard_i64` sentinel no longer surfaces as
// u64::MAX.
//
// 10. `oakengine_footage_borrow` wraps the node's own handle WITHOUT an
// addref, so the borrow and the source node share one reference: freeing
// BOTH is a double-free (reproducible heap corruption). The engine's
// borrowed-handle convention requires freeing exactly one of them (the
// tests free the borrow and leak the source shell).
// 10. `oakengine_footage_borrow` addrefs the wrapped handle, so the borrow
// and the source node shell each own their own reference: freeing BOTH is
// safe (no double-free).

//! `set_length_and_media_out` instead of an in-anchored setter) and the

//! 2. **Module `BlockSplitCommand` misplaced both split halves**
//! (crates/oaktimeline/src/undosplit.rs): the lengths were applied with
//! swapped setters — the original was out-anchored with the FIRST half's
//! length and the fresh block in-anchored with the SECOND half's length.
//! Splitting [0, 30) at frame 20 yielded [10, 30) + [0, 10) instead of
//! [0, 20) + [20, 30). The setter arguments are now swapped so the

//! 3. **`oakengine_sequence_split_clips` (batch split) was a silent no-op**:
//! the module's `BlockSplitPreservingLinksCommand` never ran `prepare()`

//! its trim command with the TRACK handle where the BLOCK belongs
//! (`trim_cmd(track, ...)`, src/timeline.rs:3034), so the redo calls

//! `oakengine_sequence_remove_track` it skips the live

//! module's `TrackRippleRemoveAreaCommand::prepare` needs
//! `oaknode_track_get_nearest_block_before_or_at`, which the oaknode
