Taxonomy Builder (router, compatibility mode)

Build outline/taxonomy.yml from papers/core_set.csv.

P0 compatibility note:

• The output contract stays the same (outline/taxonomy.yml, YAML list, >=2 levels, concrete descriptions).
• Curated domain taxonomies now live in assets/domain_packs/*.yaml instead of Python prose.
• scripts/run.py stays a deterministic scaffold/helper: detect domain pack -> load pack when available -> otherwise fall back to the generic builder.

Load Order

1. references/overview.md
2. references/taxonomy_principles.md
3. If a domain pack applies, read its references/domain_pack_<domain>.md and assets/domain_packs/<domain>.yaml
4. Otherwise read references/archetypes_generic.md
5. Calibrate naming/description quality with references/examples_good.md and references/examples_bad.md
