ADR: translate adr-ko/ to Korean, fix ADR-0013 slug, refine Status check

Follow-up to the bilingual-structure commit: docs/adr-ko/ now holds
only Korean versions (24 files translated from English placeholders),
ADR-0013 slug uses kebab-case in both folders, and the verify tool
allows translated parenthetical commentary in the Status block.

- Translate 24 English files in docs/adr-ko/ to Korean. The previous
  bilingual-structure commit had left these as English copies because
  their source content was already English; this commit fulfills the
  policy that docs/adr-ko/ contains only Korean.
- Rename ADR-0013 in both adr/ and adr-ko/ from
  ver-verification_strategy.md to ver-verification-strategy.md
  (kebab-case consistency with other ADRs).
- CLAUDE.md (ADR Translation Discipline): clarify that only the
  Status lifecycle keyword (Accepted / Proposed / Stub / Draft /
  Superseded by ADR-NNNN / Merged into ADR-NNNN) must match across
  EN and KO; parenthetical commentary and trailing list items may be
  translated.
- tools/verify_adr_lang_pairs.py: replace byte-equal Status check
  with normalize_status_keyword() which strips parenthetical
  commentary and takes only the first non-empty line.
- tests/test_verify_adr_lang_pairs.py: update existing test names,
  add coverage for translated parenthetical, translated trailing
  list, and Superseded-by-NNNN keyword equality.
