* fix(#1571): resolve schema-drift phase by token, not substring
verify schema-drift <phase> resolved the phase directory with a naive
entry.name.includes(phaseArg) test, so a non-existent phase could
silently match a different phase whose directory name merely contained
the requested token (e.g. "1" matched "11-expansion"), running the drift
gate against the wrong phase. Use the canonical phaseTokenMatches +
normalizePhaseName, matching find-phase, verify phase-completeness, and
this file's own unstarted-phase check.
Regression coverage folded into tests/schema-drift.test.cjs.
