Merge branch 'pratik/otel-phase8-log-correlation' into pratik/otel-phase9-metric-gap-fill

Bring phase-8 (log correlation) and the naming-check + BasicConfig fixes forward
into phase 9 (native-metrics gap fill). Phase 9 adds MetricsRegistry and
LedgerSpanNames.h.

Conflict resolution:
- presentation.md: took phase-9's restructured deck — sampling now lives in
  Slide 8 (Head vs Tail) and the Phase 10/11/12 future-phase slides; phase-8's
  older standalone sampling section is superseded (no content lost).
- ordering.txt/loops.txt: regenerated via generate.py.

Naming check: A/B/E/F/G green. Rule D reports 6 findings that are all check
gaps, not data errors (verified every dashboard label traces to code):
  - 3 are TraceQL `span.<attr>` references (bare attr is in L1); Rule D should
    strip the span./resource. scope prefix.
  - 2 (`reason`, `job_type`) are native OTel metric labels emitted by
    MetricsRegistry.cpp — a new source of truth the check does not yet model.
The Rule D enhancement lands on phase-1c and merges forward.
