d059f21bf3 fix(telemetry): address review findings in the workload validation harness
Fixes the review findings on this PR that belong to files it owns, plus
several defects found while verifying those fixes. Findings in files owned
by upstream branches are routed there and left untouched here.

Correctness:
- tx_submitter: advance the account sequence only on results that actually
  consume one (tes*, tec*, terQUEUED). tem*/tef*/tel* never reach the
  ledger, so advancing left a permanent gap that every later submit from
  that account inherited. Add a re-fetch hatch so a repeated non-consuming
  failure cannot livelock on the same sequence, and gate the account check
  on funded-ness rather than list length.
- validate_telemetry: filter spans by name before collecting attributes, so
  a per-span attribute contract can no longer be satisfied by a sibling
  span; require exact name equality for non-wildcard children and glob
  matching for wildcards; bounds-check every returned series instead of
  only the first.
- collect_system_metrics: select xrpld by argv[0] rather than a substring
  match on the whole command line, which averaged in unrelated processes
  and reported their RSS as xrpld's. Count genuine 0.0 CPU readings, use a
  clamped nearest-rank p99 index, and record RPC latency only on success.
- benchmark: return each verdict through a named variable instead of a
  command substitution, so the pass/fail counters survive and the exit gate
  can fire. Scale before dividing in the percentage math, which truncated a
  1.26% impact to 1.00% and cleared a 1% threshold.
- compare_to_baseline: fall back to the absolute bound when the baseline is
  not positive, so a 0 -> 500 ms jump is no longer "within bounds".
- rpc_load_generator: bound each connection to one in-flight recv(), drain
  in-flight requests before closing, use a nearest-rank percentile, and
  report delivery shortfall so an under-delivered run cannot pass with a 0%
  error rate.

Fail loudly instead of silently:
- run-full-validation: treat a consensus timeout and a missing validated
  ledger as fatal infrastructure errors, and fold the orchestrator and
  benchmark exit codes into the final status. A degraded cluster previously
  ran a full validation pass and reported misleading downstream failures.
- collect_system_metrics: warn per empty measurement source, emit
  metrics_complete, and exit non-zero instead of substituting zeros that
  pass every threshold. Require GNU date with %N rather than falling back
  to a per-sample python3 fork that costs more than the threshold it is
  measured against.
- benchmark: distinguish "could not measure" from "exceeded thresholds",
  install a cleanup trap so a failure cannot leak nodes and ports, and
  report an unusable baseline as inconclusive.
- workload_orchestrator: bound subprocess communicate() and fail the exit
  gate on per-phase errors.

Also pins the workload compose images to the versions the sibling stack
already uses, hash-pins the Python dependencies, restricts the validator
config template to loopback, corrects the dashboard and metric counts in
the reference docs, drops a span from the regression gate that cannot fire
under a WebSocket-only workload, and narrows the teardown pkill pattern so
it no longer matches processes that merely mention the work directory.

Verified with a full harness run against a local five-node cluster:
158 of 158 checks passed with no regressions detected.

a381027bb1 fix(telemetry): apply single rootless log path to workload stack
Extend the log-mount consolidation to the phase-10 workload-validation
assets, which still used the old `rippled` container path:
- docker-compose.workload.yaml: mount target renamed to /var/log/xrpld,
  source made overridable via XRPLD_LOG_DIR (default /tmp/xrpld-validation)
- otel-collector-config.grafanacloud.yaml: single glob /var/log/xrpld/*/debug.log
- run-full-validation.sh sets XRPLD_LOG_DIR to its workdir

cb9fce6890 fix(telemetry): align Phase 10 workload harness with current OTel recording surface + fix CI
The Phase 10 validation harness had drifted from the code's recording surface
and the telemetry-validation CI job was failing before it could build.

CI fix (telemetry-validation.yml):
- Replace nonexistent local action ./.github/actions/print-env with the remote
  XRPLF/actions/print-build-env (the build-xrpld job failed in 56s on this).
- Sync prepare-runner and upload-artifact action SHAs to the canonical workflow.

Recording-surface reconciliation (docker/telemetry/workload/):
- Migrate span attributes from dotted xrpl.<domain>.<field> to the bare/underscore
  form introduced by the 2026-05-13 span-attr naming redesign (tx_hash, peer_id,
  ledger_seq, consensus_mode, consensus_round, full_validation, quorum, ...).
  Dotted xrpl.ledger.hash is retained only on peer.validation.receive (shared
  constant), while consensus.validation.send uses bare ledger_hash.
- Fix attribute placement: tx.apply carries tx_count/tx_failed (not ledger_seq);
  ledger.build carries ledger_seq/close_* (not tx_count/tx_failed).
- Replace the phantom rpc.request span with the real WS root rpc.ws_message; drop
  the never-emitted duration_ms; rebuild the parent-child map accordingly.
- Add the new spans the code emits: apply-pipeline stage spans
  (tx.preflight/preclaim/transactor with stage/tx_type/ter_result), txq.*,
  consensus sub-spans (round/establish/update_positions/check/phase.open),
  ledger.acquire, grpc.*, pathfind.*. Conditional spans are marked optional so
  they are skipped (not failed) when the workload does not exercise them.
- validate_telemetry.py: service.name and Loki job label rippled -> xrpld; fix
  PARITY_SPAN_ATTRS (rename the 4 real attrs, drop the 3 that are metrics not span
  attrs); add optional-span handling that skips missing optional spans while still
  validating attributes when present.
- expected_metrics.json: rippled_ -> xrpld_ on all beast::insight/overlay metrics,
  xrpld_job_count, the 15 on-disk xrpld-* dashboard UIDs, and the real bare
  spanmetrics dimension labels.
- regression-metrics.json + baseline-timings.json: rpc.request -> rpc.ws_message.

Metrics pipeline fix:
- Switch node [insight] config from server=statsd/prefix=rippled to server=otel +
  /v1/metrics endpoint + prefix=xrpld across run-full-validation.sh,
  xrpld-validator.cfg.template, benchmark.sh and the workload compose. The
  collector has no StatsD receiver, so system metrics only reach Prometheus over
  OTLP.

Synthetic load for new spans:
- Add ripple_path_find to the RPC load generator (drives pathfind.* spans).
- Add a high-TPS txq-burst workload phase to force fee escalation (drives txq.*).

All facts verified against the *SpanNames.h headers and a live xrpld node +
collector (Tempo service.name=xrpld, tx.preflight attrs [stage,ter_result,tx_type],
279 xrpld_ Prometheus metrics and zero rippled_).
