Summary

• Add native Hungarian (hu) TN and a new ITN, completing the direction missing from NeMo. Raw-field taggers keep source text; verbalizers perform the conversion. ITN does not import TN language graphs.
• Register both directions in the CLI, packaging, cache-manifest tests and README.
• Apply the shared punctuation joiner. Hyphenated ranges keep the source spacing (100-200 → száz-kétszáz, 100 - 200 → száz - kétszáz).

Coverage and limitations

• All 205 original TN fixture lines (12 files) are retained verbatim.
• New ITN is checked against 178 reversed TN cases; the ITN output must be one of the written candidates. 12 are excluded with explicit reasons: each fixture lists only a written style that conflicts with other fixtures (dot vs space grouping, grouped ordinals, milliárd vs mrd, attached units, numeric vs named months) or a telephone layout that cannot be recovered from speech.
• Hand-written raw-field, semantic and n-best/mapping tests cover the new direction.

Test plan

• Original, reversed, raw-field and mapping tests
• CLI and cache registration regressions with NeMo imports blocked
• Full project suite on the merged master baseline (20104 passed, NeMo imports blocked)
• flake8 tn itn and git diff --check
