workflow scaffolding: roadmap, progress, amendments

Login and dashboard shipped. Project CRUD shipped. The 2D editor is next, and it’s the biggest piece in Phase 1 by a wide margin. Felt the right moment to add scaffolding before pouring more code into it.

Three new docs and one new command:

• ROADMAP.md — task-level breakdown the bible doesn’t have. Phase 1 detailed, later phases sketched.
• PROGRESS.md — where we left off, what’s blocked, “resume here” pointer for the next session.
• AMENDMENTS.md — anywhere the code intentionally disagrees with the bible. Stops the bible from quietly becoming a lying source of truth.
• /checkpoint — slash command that updates PROGRESS.md. Either standalone, or chained as /implement {task} /checkpoint to log work as it lands.

The point: make the next session’s first 60 seconds about resuming instead of re-deriving state.
