feat(generation): first-class output-language support for generated docs

[RaghavChamadiya]

What

Promotes the config-only wiki output-language setting (#99) to a first-class option.

• repowise init --language <code>: choose from 15 languages (en, ru, es, fr, de, zh, ja, ko, it, pt, nl, pl, tr, ar, hi). Prose is generated in that language; code, file paths, and symbol names stay untranslated.
• Advanced interactive init now asks for the output language (English default) and shows it in the config summary.
• The choice persists to .repowise/config.yaml (single-repo and workspace init), so repowise update regenerates changed pages in the same language.
• Paths that silently defaulted to English now honor the configured language: workspace generate, the server regenerate job, and the pipeline orchestrator fallback config. PageGenerator also falls back to config.language when the argument is omitted, so future callers cannot repeat that bug.
• The language map moved to a dependency-free leaf module (generation/languages.py) so the CLI validates the flag at startup without importing the page-generator stack.

Docs

README (one line in the Docs layer row), CLI reference, user guide, CONFIG.md, changelog. Changing the language later does not retranslate existing pages; re-run init --force --language <code>.

Testing

• All 2173 unit tests pass; added a test that PageGenerator picks the language up from GenerationConfig when the arg is omitted, and updated the advanced-config keys test.
• Verified end-to-end: indexed a real repo with --language hi (openai / gpt-5.4-nano); generated pages come out in Hindi with code and symbol names untranslated, and language: hi lands in config.yaml.
