Finalize vault: fix Bases syntax, add Quartz fields, improve template

Changes from Codex review:
- Bases: rename .md -> .base, fix filter to file.name == 'index.md',
  fix formula to now() (not date(now)), add proper views section with
  table view and column order, add displayName for properties
- Frontmatter: add 'description' (SEO/link previews) and 'draft' (publishing
  control) fields for Quartz compatibility
- Template: add '## Scope' section, add '## Related Research' section for
  explicit wikilinks between topics, use path-qualified wikilinks in detail
  files section to avoid ambiguous basenames across topics
- README: fix cross-vault wikilink claim (separate vaults can't resolve
  cross-vault links; Quartz can't publish outside its content tree),
  document draft field, clarify that tags don't create graph edges

-Wikilinks between detail files within a topic, and between topics via shared tags, create a knowledge graph visible in Obsidian's graph view. Cross-links to [[index|Idea Dump]] entries (e.g., research that feeds a product idea) work natively since both vaults live under the same Obsidian vault.
