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.

End-to-end test streaming three float32 signals via a MARTe2 UDPStreamer
app into a standalone StreamHub with the recorder enabled, then validating
the recorded FileWriter-compatible .bin against the streamed input with
validate_binary.py. All recorded rows are byte-identical to input rows.

Parse the optional +Recorder block in Initialise (Enabled/AutoStart/
Directory/MaxFileMB/KeepFiles/StagingMB/FlushIntervalSec/MinDiskFreeMB/
Signals, MB->bytes), apply it to each session before Start (static and
dynamic sources). Drive recorder disk I/O from the push loop via
RecorderFlushTick, and add recStart/recStop/recInfo WS commands plus a
recStatus broadcast/snapshot.

Each session owns a BinaryRecorder. The receive thread configures the
recorder layout at CONFIG time and captures each data packet; the push
thread performs all file I/O via RecorderFlushTick. WS subset overrides
are adopted through an epoch-deferred handoff mirroring the trigger path.
Arm/disarm/flush/info are exposed for StreamHub-level control.

Add a FileWriter-compatible per-source binary recorder: native-type encode
and TypeDescriptor mapping, FileWriter header serialization, subset/quantized/
ACCUMULATE row serialization, and push-thread double-buffer flush with size-cap
rotation, keep-N pruning, fdatasync cadence, disk-free and staging-overflow
guards. Covered by 12 GTests; full suite (83) green.

Lossless packet-decode capture to FileWriter-compatible per-source binary
files with size-capped rotation, config + WS control, and double-buffered
flush on the push thread (Approach C).
