msd-core/tests/bug-2796-arg-parsing-regression.test.cjs

/**
 * Regression test for bug #2796
 *
 * roadmap.update-plan-progress used positional-only arg destructuring:
 * `const phaseNum = args[0]`. When called with the flag form documented in
 * execute-phase.md:228 (`--phase "TEST" --plan "01" --status "complete"`),
 * args[0] was the literal string "--phase", which was passed to findPhase().
 * findPhase found no phase named "--phase" and returned `updated: false` with
 * `reason: "no matching checkbox found"`, silently no-oping. ROADMAP.md plan
 * checkboxes never advanced.
 *
 * The stateBeginPhase handler already uses parseNamedArgs and is NOT affected.
 *
 * Fix: roadmap-update-plan-progress.ts now checks for --phase <value> before
 * falling back to positional arg[0] (filtering out flag tokens).
