Tom Boucher a54feb4216 fix(#2440): per-counter progress ratchet — total_plans always takes derived value (#2468)
* fix(#2440): per-counter progress ratchet — total_plans always takes derived value

Two sites fixed (targeted — existing body-only write tests preserved):

Site A — read path: shouldPreserveExistingProgress (state-document.cts:167)
removed total_plans from the all-or-nothing ratchet check. It now joins
total_phases as an always-derived counter. Only completed_phases and
completed_plans keep ratchet behaviour (they are monotonic). This fixes
gsd-tools query state.json reporting stale total_plans when a curated
completed_plans triggers the ratchet.

Site B — write path: applyStatePreservation (state-transition.cts:162)
gained a deriveProgressKeys opt-in flag. When true (passed by
cmdStatePlannedPhase only), total_plans and total_phases take the
derived (post-sync) value instead of the wholesale curated restore.
When false (the default — state.update, state.patch), the existing
#3242 wholesale protection stays fully in force. This fixes the
state planned-phase verb writing a stale total_plans.

The opt-in approach preserves all 8 existing #3242/#1264/#500 body-only
write tests that assert wholesale progress preservation during non-
progress updates.

Tests:
- tests/state.test.cjs: 4 unit tests for shouldPreserveExistingProgress
  (total_plans upward/downward/equality + completed_plans ratchet active).
- tests/state-transition.test.cjs: 2 #2440 regression tests for
  deriveProgressKeys=true (total_plans takes derived; boundary at equality).
  The existing !resync wholesale-restore test stays unchanged (default
  behavior preserved).

References: #2440; #1446 (total_phases read-path fix — same principle);
#3242 Bug A (body-only preservation — protection preserved via the opt-in
gate); ADR-1769 (applyStatePreservation table-driven preservation).

Fixed 2468

/gsd-stats and STATE.md progress no longer freeze stale total_plans — the progress ratchet was applied to the whole progress record, so any single counter decreasing (e.g. completed_plans) froze every field including total_plans. Now total_plans always takes the freshly derived value (joining total_phases from #1446), so it corrects in both directions — upward when a new phase adds plans, downward when a milestone reorganization removes phases. The write-path applyStatePreservation also switched from wholesale block restore to per-field merge, so state planned-phase writes a consistent total_plans instead of the pre-transform stale value.
