Subject: [PATCH] test(tools): add coverage for collapsed model-direct call
 under code mode

Add two executor-level tests covering the previously uncovered branches
in createExecution:
- collapsed call (non-aborted signal) returns UNKNOWN_TOOL
- collapsed call (pre-aborted signal) returns ABORTED_BEFORE_DISPATCH
