Claude Owner 2bed5f38b7 fix(melo-test): unidic download is mandatory, not optional ...

User got past wheel build, then hit at startup:

  RuntimeError: Failed initializing MeCab
  [ifs] no such file or directory:
      .../site-packages/unidic/dicdir/mecabrc

Root cause: MeloTTS's text/cleaner.py unconditionally imports the
japanese module, which initializes MeCab.Tagger() at module load
time. So even Korean-only use needs the unidic dictionary data,
which is a separate ~250MB download.

- README: add explicit `python -m unidic download` step after
  pip install, and a troubleshooting entry for the mecabrc error.
- Dockerfile: run `python -m unidic download` during image build so
  the container is usable immediately.
