Address review: end-to-end coverage that gstack-learnings-log (which
imports ../lib/jsonl-store.ts) actually executes from each installed
runtime root — agents sidecar, Codex, Factory, OpenCode, and Kiro —
built by the real setup shell code, in both symlink (IS_WINDOWS=0) and
Windows copy (IS_WINDOWS=1) modes. A negative control proves the probe
fails on the pre-fix bin-without-lib layout.
Verified: all 10 positive cells fail against upstream/main's setup and
pass with the fix.
