Migrate cmdStateSync, cmdStatePrune, cmdStateUpdate (state.cts) onto the
STATE.md Transition Module substrate and close the maintenance bug pair
#1760/#1761 (ADR-1769, epic #1769). Completes the substrate: all 10
lifecycle/maintenance transitions now route through transitionCore.
- Add {kind: 'sync'|'prune'|'update'} to StateTransitionIntent with syncCore,
pruneCore, updateCore in src/state-transition.cts.
- updateCore: body-only single-field update (strip/reassemble), mirroring the
pre-migration cmdStateUpdate contract.
- pruneCore: pure content→content section pruning (Decisions / Recently
Completed / resolved Blockers / Performance Metrics rows at or below cutoff),
byte-identical tokenizeHeadings splicing. Adapter owns currentPhase, dry-run,
and STATE-ARCHIVE.md.
- syncCore: body writes (Total Plans in Phase, Progress bar, Last Activity)
given disk-derived numbers. Adapter owns the disk scan + roadmap scope.
- #1760: cmdStatePrune now derives currentPhase from 'Current Phase' OR 'Phase'
(the canonical template emits 'Phase: X of Y'), so prune engages on
template-conformant STATE.md instead of bailing 'Only 0 phases'.
- #1761: cmdStateSync skips the Progress write (percent=null) when a milestone
version is set in frontmatter but the ROADMAP has no versioned heading for it
(milestone cannot be bounded). Projects without a milestone version are
unaffected. Leaves progress untouched rather than silently writing fallback-
derived wrong values.
- Regression: bug-1760 (prune engages on template field) + bug-1761 (sync
leaves progress untouched when unbounded). ADR-1769 marked Accepted.
All 82 transition + 515 regression tests pass.
Closes#1793
