Upgrade confirmed format-incompatible before use (job6 gate, BATCH-2):
gsd-pi 3.0.0 no longer writes .gsd/ROADMAP.md (verified by generating a
real test milestone in a scratch project) — state moved to .gsd/STATE.md,
.gsd/gsd.db (authoritative DB), and one .gsd/milestones/<ID>/<ID>-ROADMAP.md
per milestone, all in a different markdown shape. Every grep/awk in
status-reporter.md PHASE 3 would silently print 0/blank against the old
path instead of erroring.
Rewired PHASE 3 to read `gsd headless query` (stable JSON snapshot, no LLM
call) instead of scraping markdown — smoke-tested against both the absent
case (this repo, no .gsd/) and a real gsd-managed scratch project.
plugins.lock.json pin bumped deliberately to 3.0.0 (update-all.sh honors
the pin; this is the required manual bump).
