♻️ refactor(tsl): decouple skill routing from static docs

删除静态文档中对 tsl-syntax-reference / tsl-api-reference 的导航路由，
改由运行时按需自动触发；语法/API 事实的所有权与 fail-closed 约束
只保留在 rulesets/tsl/index.md 这一唯一权威载体。

- docs/tsl/index.md：删 4 行 skill 路由及重复的所有权/fail-closed 段，回归纯分流
- docs/tsl/modules/index.md：删 API 路由及指向已删 syntax 的 3 处回跳
- docs/index.md：删 skill 导航行及 2 条指向不存在文件的死 catalog 链
- docs/tsl/syntax/index.md：删除旧路径兼容 stub，不再保留任何兼容
- rulesets/tsl/index.md：删首跳 2 条 skill 导航，保留事实边界与 Fail closed
- 同步修正相关测试断言
