Add a Stress Tests section (per-case table + per-axis scaling-curve images)
after Performance, guarded so it is omitted when no stress data is present.

report_build.py reads stress_results.json (when --stress-results given),
adds a stress block (cases + by_axis), per-axis scaling-curve PNGs, aggregate
stress headline metrics, and stress regression rows vs the previous run.
Degrades to no stress section when the file is absent.

Send the "stress matrix invalid" message to stderr and echo a WARN on
stress_run.py soft-failure, matching the script's existing soft-fail
echo convention.

When --stress is passed, run the capacity matrix (stress.py/stress_run.py)
after the correctness phase, writing stress_results.json into OUT_DIR/stress
and handing its path to report_build.py for the PDF's Stress Tests section.

Add 50k/100k/250k-element size cases (~195 KB–954 KB packets) to the DS and
hub size axes so the stress suite exercises UDPSClient multi-fragment
reassembly under load, and lift the now-outdated 64 KB validation cap to the
1 MiB deliverable cap (UDPS_CLIENT_MAX_PACKET_BYTES). Slowed producers keep
bandwidth realistic.

Full-chain orchestrator (run_chain_e2e.sh) now runs the starter set green
(3 pass). Fixes found bringing the chain up end-to-end:
- client: gorilla/websocket cannot survive a read deadline (next ReadMessage
panics "repeated read on failed connection"); replace the poll-with-deadline
loop with a background reader goroutine + mutex-guarded state.
- orchestrator: guard env.sh's unbound LD_LIBRARY_PATH under set -u.
- scenarios/gen_data: centralize NUM_ROWS/ROW_DT and enforce sine freq to be a
multiple of the buffer fundamental (LOOP_HZ=5 Hz) so the looped FileReader
buffer is a seamless waveform; align starter freqs (5/5/10 Hz).
- gen_cfg: FileReader allows exactly one consuming Function, so route tapped
(oracle=fed/both) sources through the DDB (ReaderGAM->DDB, then StreamGAM and
TapGAM both read DDB) instead of a second FileReader consumer.
- validate_waveform: fidelity gates correctness (bit-exact / within one quant
level); sine shape becomes a gross frequency-sanity gate (corr>=0.5) plus a
tracked corr/nRMSE quality metric, since per-sample wall-clock calibration
(Phase-A) and FULL_ARRAY packed timestamps (Phase-A4) are still pending.
