- core.cjs: add filterPlanFiles, filterSummaryFiles, getPhaseFileStats,
readSubdirectories helpers; use them in searchPhaseInDir and getArchivedPhaseDirs
- gsd-tools.cjs: add parseNamedArgs() helper; replace ~50 repetitive indexOf/ternary
patterns in state record-metric, add-decision, add-blocker, record-session,
begin-phase, signal-waiting, template fill, and frontmatter subcommands
- phase.cjs: decompose 250-line cmdPhaseRemove into renameDecimalPhases(),
renameIntegerPhases(), and updateRoadmapAfterPhaseRemoval(); import readSubdirectories
- workstream.cjs: import stateExtractField from state.cjs and shared helpers from
core.cjs; replace all inline regex state parsing and readdirSync+filter+map patterns
All 1062 tests pass.
