Removes Voyage's measurement, statistics and export apparatus (decision 189;
condition 175 met in step 1) and the R-a leftovers: lib/stats/, lib/exporters/,
the otel-export and post-bash-stats hooks, yardstick, end-state and comparison
gates, synthesis-measure, gold-scorer, docs/observability.md,
examples/observability/, docs/T1-cc26-delegated-orchestration.md and their
tests and fixtures. The six command stats phases and the /trekexecute
main-merge event blocks go; intent-approval --stamp no longer emits
brief-approved. README and docs point to Claude Code's own OpenTelemetry.
