test(gen-script): lock in to_rule() inline-# handling with regression tests

新增 2 个 test method 覆盖 b4a4769 修复的边界 case：
- test_to_rule_strips_inline_hash_comment_before_classifying_no_resolve
  锁定带 inline # 注释的条目（本次修复的真实场景）
  + 验证注释里出现 'no-resolve' / ',DIRECT' 字符串不被误处理
- test_to_rule_preserves_canonical_forms
  锁定 happy path（纯规则、带 no-resolve、带行尾空白）

为让 test_checked_in_router_projections_match_the_rule_source 通过，
同步重生成 router/direct-plain.txt 和 router/direct-rules.yaml。
这俩投影文件自 907fe9d 起就 stale 14+ 条规则（国内 LLM、UGREEN、
Steam 段全没同步），本次连同 b4a4769 的修复一起补齐。

测试结果：python3 -m unittest discover -s tests
  Ran 9 tests in 0.028s — OK
