feat: implement memory-engineering bridge (--with-memory flag and readiness signals)

[THRISHAL12345]

Summary

Integrates the memory-engineering bridge by adding --with-memory scaffolding to loop-init and Memory Ready signals to loop-audit, mirroring the existing harness-foundry implementation.

Changes

• New pattern or starter (followed templates/pattern-template.md and updated registry.yaml)
• Documentation / example improvement
• Tool changes (loop-init and loop-audit)
• Story (includes a real failure or surprise and the lesson learned)

Checklist (from CONTRIBUTING)

• All required sections are present for patterns
• Links work from README.md, patterns/README.md, starters/README.md, and docs/index.md
• No secrets, tokens, or internal company URLs
• STATE.md examples use the .example suffix
• Safety-related content references docs/safety.md
• Ran node tools/loop-audit/dist/cli.js . (or on the starter) and addressed all findings

Testing / Dogfooding

• loop-audit passes on the affected starters or this repository
• Manually reviewed the generated state and skill output

Screenshots / Examples

loop-init . --with-memory

CLI Output

Memory engineering:
  copied: ...\templates\memory-tiers.md
  copied: ...\templates\memory-budget.md

Memory engineering stack ready (memory-tiers.md, memory-budget.md)

---

loop-audit (when memory is scaffolded)

CLI Output

Findings:
  ✓ Memory tiers defined (memory-tiers.md).
  ✓ Memory budget defined.

---

loop-audit (CTA when Loop Ready score is above 80 and memory is missing)

CLI Output

Next after Loop Ready 80+: version this loop's memory
