release: bump version 9.0.0 → 9.0.1

[nullhack]

Changes

• Derived delivery order: Removed static Delivery Order section from product_definition.md template. Feature selection now derives order from context map dependency count (lowest first), ties broken by WSJF scoring.
• Research template restructured: Moved research template to domain/subdomain hierarchy (docs/research/<domain>/<subdomain>/<author_year>.md).
• Template cleanup: Removed header comments from domain_spec.md, glossary.md, and product_definition.md templates.
• Removed stale file: Deleted docs/research/CONTRACT_spec_simulation_redesign.md.
