Pratik Mankawde 3852b5ae4b fix(telemetry): address review findings and PR #6437 comments
Critical fixes:
- Restore accidentally removed mallocTrim call and MallocTrim.h include
- Add missing shouldTraceLedger() to interface and all implementations
- Derive networkId/networkType from config_->NETWORK_ID (0=mainnet,
  1=testnet, 2=devnet) instead of leaving defaults unpopulated
- Clamp sampling_ratio to [0.0, 1.0] in config parser

PR comment fixes:
- Rename rippled -> xrpld in service name defaults, getTracer() calls,
  Docker network, comments, and docs/build/telemetry.md
- Remove exporter config option (only otlp_http supported)
- Add trace_ledger and service_name to example config
- Clarify head-based sampling semantics in config comments
- Add filter descriptions for span intrinsic filters in Grafana datasource
- Add inline comments to Docker Compose services

Docker/config improvements:
- Remove deprecated version: "3.8" from docker-compose.yml
- Pin images: collector 0.121.0, grafana 11.5.2
- Add health_check extension to otel-collector-config.yaml
- Comment out Tempo metrics_generator remote_write (no Prometheus service)
- Add Prometheus datasource caveat in Grafana datasource config

Other:
- Revert unrelated formatting changes in ServiceRegistry.h
- Change Conan telemetry default to False (matches CMake OFF)
- Add CLAUDE.md-required docs (ASCII diagrams, usage examples,
  @note thread-safety) to Telemetry.h and SpanGuard.h

# Grafana Tempo configuration for xrpld telemetry stack.
#
# Runs in single-binary mode for local development.
# Receives traces via OTLP/gRPC from the OTel Collector and stores
# them locally. Queryable via Grafana Explore using the Tempo datasource.
#
# Search filters are configured on the Grafana datasource side
# (grafana/provisioning/datasources/tempo.yaml). Tempo auto-indexes
# all span attributes for search in single-binary mode.
#
# For production, replace local storage with S3/GCS backend and adjust
# retention via the compactor settings. See:
# https://grafana.com/docs/tempo/latest/configuration/
