Cite the CODESYS Forge thread, the official scripting docs index,
the Schneider Electric mirror with the historical signature, the
SP21 Patch 5 release notes, and the local ScriptSystem.pyi stub
that is the primary evidence for the API removal.

Investigation of the system.execute_on_primary_thread removal:
- Confirmed gone in SP21 Patch 5 (no entry in ScriptSystem.pyi stubs).
- Single call site is watcher.py:195, structural to the bg-thread design.
- Proposes single-threaded primary-thread loop with system.delay() for
message-pump time. No Node/TypeScript changes needed.

v0.3.0 returning-watcher architecture — background thread polls for commands
and marshals execution onto the CODESYS UI thread, keeping the IDE fully
responsive between operations. File-based IPC with atomic writes, async mutex
command serialization, headless fallback, and 35 passing tests.
