Closes brain-retro 2026-05-20 #17 — one-off Node script for investigating
the Glob p50=12.7s anomaly from initial retro. Parses transcript JSONL,
prints top-N slowest Glob round-trips with pattern + path.
Smoke-tested on session 553717ec (5h+ session): finds 32 Glob calls,
median 12690ms (matches retro finding), top-5 all 'docs/adr/**' at
20265ms — Glob recursive on ADR directory is the apparent culprit.
NOT production code path — never imported by parser/hook/analyzer.
Run on demand: node tools/glob-latency-investigator.mjs <transcript.jsonl>.
