The final whole-branch review (post Task 10) found two real cross-task
integration bugs:
- run_e2e.sh's coverage-instrumented scenario re-run only rebound OUT_DIR
in its subshell, not WORK. proc_perf.py/plots.py write perf_*.json and
wave_*.png into WORK, so every --cpp-coverage run (the default) silently
clobbered the primary pass's perf/waveform data with the instrumented
re-run's numbers before report_build.py read them -- defeating the
"uncontaminated performance metrics" goal of the coverage-double-run
design. Fixed by rebinding WORK the same way OUT_DIR already was.
- report_build.py's build_e2e() iterated all results["scenarios"] with no
kind filter, so the direct/recorder/debug/tcplogger scenarios (already
covered by their own dedicated report sections since Task 8) also leaked
into the chain-only Scenarios/Performance sections and headline e2e
pass/fail count as degenerate rows. Fixed by filtering to kind=="chain".
Verified end-to-end with a full ./run_e2e.sh run: coverage pass now writes
to /tmp/chain_e2e/coverage_pass/ (confirmed via log), and report_data.json's
e2e section now reports 51 (chain-only) scenarios instead of all 56.

Extends report_build.py with build_by_kind() (per-scenario-kind pass/fail
rollup) and a ported build_stress()/stress_headline()/stress_plots() (scaling
curves per stress axis), wires both into the headline KPIs, regression
tracking, and report_data.json. E2E_Report.typ renders the four new
per-kind tables plus a Stress Tests section (per-axis case tables + scaling
plots, gracefully degrading to placeholders when a kind/stress data is
absent). run_e2e.sh now passes --stress-results so the report actually
receives real stress data instead of silently omitting it.
