Replace StatsD UDP metric transport with native OpenTelemetry Metrics SDK
export via OTLP/HTTP behind the existing beast::insight::Collector interface.
- Task 7.1: Link opentelemetry-cpp to beast module in CMake when telemetry=ON
- Task 7.2: New OTelCollector class mapping beast::insight instruments to OTel
SDK (Counter, ObservableGauge, Histogram, Counter<uint64>) with OTLP/HTTP
export via PeriodicMetricReader at 1s intervals
- Task 7.3: Add server=otel branch to CollectorManager with endpoint config
- Task 7.4: Update otel-collector-config.yaml to use OTLP receiver for metrics
pipeline (StatsD receiver commented out for backward compat)
- Task 7.5: Metric names preserved via dot-to-underscore formatting matching
StatsD->Prometheus conventions
- Task 7.6: Rename Grafana dashboards from statsd-* to system-*, update titles
and UIDs from "StatsD" to "System Metrics"
- Task 7.7: Update integration test to use server=otel, verify OTLP metrics
- Task 7.8: Update runbook, TESTING.md, config reference, and data collection
reference docs

Add the close time span and its 6 attributes to the Phase 4 consensus
span table and attribute table in 09-data-collection-reference.md.

Add full consensus tracing with deterministic trace ID correlation
and establish-phase instrumentation:
- Deterministic trace_id from previousLedger.id() for cross-node
correlation (switchable via consensus_trace_strategy config)
- Round-to-round span links (follows-from) for causal chaining
- Establish phase spans with convergence tracking, dispute resolution
events, and threshold escalation attributes
- Validation spans with links to round spans (thread-safe via
roundSpanContext_ snapshot for jtACCEPT cross-thread access)
- Mode change spans for proposing/observing transitions
- New startSpan overload with span links in Telemetry interface
- XRPL_TRACE_ADD_EVENT macro with do-while(0) safety wrapper
- Config validation for consensus_trace_strategy
- Test adaptor (csf::Peer) updated with getTelemetry() stub

Add a new trace span in doAccept() capturing ledger close time details:
- xrpl.consensus.close_time: agreed-upon close time (epoch seconds)
- xrpl.consensus.close_time_correct: whether validators converged
(per avCT_CONSENSUS_PCT = 75% threshold)
- xrpl.consensus.close_resolution_ms: time rounding granularity
- xrpl.consensus.state: "finished" or "moved_on" (consensus failure)
- xrpl.consensus.proposing: whether this node was proposing
Update Tempo datasource with close time filters, plan docs with
new span inventory, and add test coverage for the attribute pattern.

- Add Tempo 2.7.2 service to docker-compose with local storage
- Add otlp/tempo exporter to OTel Collector traces pipeline
- Add Tempo Grafana datasource provisioning with node graph
- Update 05-configuration-reference.md examples with Tempo
- OTel Collector fans traces to both Jaeger and Tempo simultaneously
Jaeger provides a standalone UI at :16686 for quick lookups.
Tempo is queryable via Grafana Explore using TraceQL and is the
recommended backend for production (supports S3/GCS storage).

Split document index into Plan Documents and Task Lists sections.
These files were introduced in this branch but missing from the index.
