HS-plan: add scoreboard + require loop agent to maintain it

plans/hs-conformance-scoreboard.md is the at-a-glance ledger
(baseline 1213, merged 1240, +2 pending on worktree). Added rule 11
to hs-conformance-to-100.md so the loop agent bumps it per commit.

+## Maintenance
+
+After each cluster commit, update:
+- `Merged:` pass count + `delta` line at top
+- The row's `Status` / `Δ` / `Commit` in the relevant bucket
+- The buckets roll-up table counts
+
+Use `mcp__hs-test__hs_test_run(start=0, end=195)` + targeted-suite runs to get the real number; don't run the full suite every iteration (hangs on 196/199/200/615/1197/1198).
