feat: scalable entities & patterns architecture

- Entity format: 3-line compact registry (### Name / key facts / status+links)
  Heavy entries promoted to thread files. Cross-domain pointers for shared entities.
- Pattern satellites: core patterns.md cap reduced from 110→70 lines (5.5KB).
  Domain-specific patterns go in satellite files loaded only by owning skill.
- Reflect: pattern routing rules, entity format enforcement (step 3b)
- Housekeeping: entity registry enforcement (step 5b), glacier inactive entities
- Evolve: scorecard metrics for pattern distribution + entity compression ratio
- README: updated entity example to 3-line format
