feat(generation): 四向八向使用全方向独立合同

[xyh202131]

变更内容

• 四向改为 east、west、north、south 四个真实生成方向，八向改为八个真实生成方向
• Workflow Controller、Quick Start、Workflow Editor 的生成、选择、确认、重试与微调统一使用 generationDirections
• CharacterData v2 保留显式 west 等方向的真实模板与动作序列，不再错误回退为 east 镜像
• 发布与渐进导出按项目方向规格校验完整真实序列；缺少任一必需方向时明确拒绝
• 发布态 v1 多方向镜像资产在创建和更新时均拒绝，单向旧资产继续兼容
• 单向资产仅保存 east 真实序列时，可正确导出为默认序列
• 已同步最新 main；新增动作继续复用 main 的现有 Workflow 路径，不恢复旧的自建流程

验证

• 后端全量：1409 passed，14 skipped，覆盖率 94%
• 前端方向逻辑及其余全量：72 个测试文件、1042 条用例全部通过
• 前端覆盖率：Statements 92.21%，Branches 86.65%，Functions 95.91%，Lines 95.20%
• 前端 lint、typecheck、正式 build 通过
• 后端 Ruff 与 git diff --check 通过
• main 新增的字体交付测试在 Windows 长盘符路径下存在 URL pathname 可移植性问题；该问题不属于本 PR，正式 Vite build 已通过

审阅了后端方向完整性校验、生成入口，以及前端方向配置和工作流消费者。当前有两处会让新合同在正常路径下失效：前端仍生成旧的源方向子集；API 对 v1 多方向资产绕过了新增校验。固定提交范围的 git diff --check 通过；后端和前端测试未能运行，因为环境中没有 uv/pytest，且未安装前端依赖。

[fennoai]

Reviewed the full fixed diff for the direction-generation contract. The backend contract changes are directionally consistent, but two integration paths still allow incomplete or incorrectly published multi-direction assets. The local Python and frontend test runners were unavailable in this environment (pytest/uv missing; vitest not executable).

Additional findings

• backend/packages/app/src/windup_app/web/api/character.py:?: [P1] Validate legacy multi-direction assets before publishing: This guard bypasses validate_character_directions whenever data.version < 2. CharacterStatus.from_character_data can still classify a legacy v1 payload as PUBLISHED, so create/update accept v1 characters in four- or eight-way projects even though the new validator explicitly rejects those mirror-based assets as incomplete. Remove the version check here and let the validator retain only the intended v1 single-direction compatibility case.
