feat: add alignment-analyzer Task agent for GSD-only state

[snipcodeit]

Summary

When state detection finds GSD-Only or GSD-Mid-Exec state, spawn an alignment-analyzer Task agent that reads .planning/ files and produces a structured alignment report at .mgw/alignment-report.json.

Milestone: v3 — State Detection + Alignment | Phase 19: Alignment & Drift Logic

Implementation Complete

Implemented in commit 4efccc8 on branch feat/mgw-gsd-architecture-repair.

Added align_from_gsd step to commands/project.md: spawns an alignment-analyzer Task agent that reads GSD artifacts (.planning/PROJECT.md, ROADMAP.md, STATE.md) and writes a structured alignment report to .mgw/alignment-report.json, then maps GSD milestones to GitHub milestones.

Part of PR #102.
