Three changes:
1. Fix the bench harness's set_pou_code case. The previous version
passed POU_PATH / DECLARATION_CODE / IMPLEMENTATION_CODE, but the
script template expects POU_FULL_PATH / DECLARATION_CONTENT /
IMPLEMENTATION_CONTENT. Plus the recently-added SET_DECLARATION /
SET_IMPLEMENTATION boolean flags from 35abc8c. With these
corrections, set_pou_code passes for the first time in the bench.
2. Add bench-results-v5.json from a fresh persistent-mode run on
MCPTest2 v1.3.4.0. All 10 cases PASS.
3. Update TEST_OVERVIEW.md with the v5 numbers alongside the v1
historical numbers. v5 is ~2x faster across the board than v1
(likely the cumulative effect of the ScriptManager cache removal +
SP22 Patch 1 IPC improvements). first-cold open_project is slower
than v1 (10.6 s vs 7.7 s) -- one-shot, noise probably; warm
already-open call dropped from 740 ms to 314 ms.
The v5 set_pou_code pass is the third end-to-end signal that the
omitted-decl wipe fix is good (after the e2e regression test and the
live PLC_PRG restoration earlier today).
