Jeffrey (Dongkyu) Kim 541967e96c korean-slang-writing (#133): fix broken seed namuwiki URLs + add encoding invariant test ...

Reviewer flagged 4/30 seed namuwiki_url values returning HTTP 404 on live
Namu Wiki. These URLs are part of the documented response contract and get
surfaced directly to agents, so broken links are a functional bug, not a
cosmetic one.

Root causes per entry:
- 중꺾마: wrong 꺾 codepoint (U+AFFA 꿺 instead of U+AEBE 꺾).
- 아아: typo in aliased title (아이스 아메리칸노 instead of 아메리카노).
- 어쩔티비: missing 받침 (어쩌티비 instead of 어쩔티비).
- 당모치: encoding correct but no live Namu Wiki article exists; dropped.

Also fixes two separately-broken 중꺾마 example URLs in SKILL.md
(U+AFBE 꾾 instead of U+AEBE 꺾) — these were discovered while auditing
the seed and would have surfaced as 404 to agents following the example
snippets.

Adds two regression tests:
- test_each_seed_url_decodes_to_term_or_alias: decodes every seed URL's
  path segment and asserts it equals the term or one of its aliases.
  Catches Hangul-codepoint typos offline (no network dependency) and
  would have caught all 3 encoding bugs in this PR.
- test_no_seed_entry_points_at_known_missing_namuwiki_page: locks the
  당모치 drop so nobody re-adds an entry pointing at a page that does
  not exist on Namu Wiki.

Fixes the existing LookupNetworkTest assertion that was hard-coding the
broken URL — it now derives the expected URL via build_namuwiki_url()
so the test cannot drift out of sync with the helper again.

Verification:
- PYTHONPATH=.:scripts python3 -m unittest scripts.test_korean_slang_writing -> 40/40 pass
- Live GET with browser headers against all 29 remaining seed URLs -> 29/29 return 200
- npm run ci -> exit 0
- Manual QA: slang_search on 중꺾마, 어쩔티비, 아이스 아메리카노 returns
  correct URLs; slang_lookup live-fetches 중꺾마 and extracts the
  canonical title '중요한 것은 꺾이지 않는 마음'.
