Remove all S0-S5 stage code, specs, plans, memorys, harness, packages,
and infrastructure. Retain only docs-design/ (original product/business
requirements) and .gitignore as the starting point for v2.0 architecture.
v1 implementation preserved on branch dev/1.0.0.
M0 (product shell / user entry): /login page, app-shell nav with current user + role + logout, real project list (replaces hardcoded demoProjects), create-project + auto first-version, role-aware home entries. Auth uses native-form + 303 PRG redirect + HttpOnly huijing_api_token cookie; new proxies for auth(login/logout/me) and projects(create/version).
M1 (creator flow): surface deterministic-generator demo label; switch prompt/save/compile routes from raw-JSON passthrough to PRG redirect back to workbench + status banner; 401/403 -> /login, empty-state create-version fallback. M1-T5 (per-version playable preview) deferred to M2 (Path A): verified blockers = stub logic compiler + no package-serving endpoint + tested S2 boundary; workbench honestly labels preview as a later capability and links the fixture as a clearly-marked platform sample (no orphan jump, S2 boundary untouched).
Verification (@huijing/web): typecheck + lint + 88 unit tests + next build + git diff --check all green. End-to-end (DB-backed create/generate/save/compile) requires real Postgres and is not claimed verified in-sandbox.
