Migrate cmdStatePatch (state.cts) onto the STATE.md Transition Module substrate
and close the curated-field clobber bug class #1743/#1695 (ADR-1769, epic #1769).
- Add {kind: 'patch'} to StateTransitionIntent, with patchCore in
src/state-transition.cts. Applies each caller-supplied {field:value} pair via
stateReplaceField over the full content (body + frontmatter), tracking
updated vs. failed. data.updated/data.failed mirror the CLI output shape.
- Collapse cmdStatePatch to a transitionCore dispatch. Field-name validation
(security) and the resync-progress decision stay in the adapter.
- #1695/#1743 fix: extend the #1230 delta heuristic in readModifyWriteStateMd to
the curated current_phase_name, table-driven via
getFieldClassification('current_phase_name').preservation === 'preserve-always'.
When a write does NOT change the body Phase: source line, the curated
frontmatter value wins over syncStateFrontmatter's body re-derivation (which
harvests a wrong parenthetical aside — #1695). begin/planned/complete-phase
rewrite their body Phase line, so the delta does not fire for them and
current_phase_name still advances.
- Regression: bug-1695-state-patch-clobbers-phase-name.test.cjs — unrelated
patch preserves curated current_phase_name; patching the Phase source advances.
All 70 transition + 493 regression tests pass (state/phase/milestone + #905/#397/#3242 lineages).
Closes#1791
