docs(P51): full presentation rework — scope, story arc, visuals, appendix

Major rework of both presentation decks based on leadership feedback.
Addresses: story arc, concept clarity, scope clarification, more visuals,
appendix for detail-heavy slides, and a complete Road to the North Star.

6 new mermaid diagrams:
- platform-works-03-scope-boundary (Upstream → Contract → ACDL → AWS)
- developer-experience-01b-scope-boundary (both consumer paths + scope)
- platform-works-04-confidence-signal (6 inputs → score → gate → decision)
- platform-works-05-attestation-flow (deploy → gate → approver → evidence)
- developer-experience-04-promotion-journey (dev → qa → prod → dr)
- road-to-north-star (v1.0 demo → v1.9 → v1.10 → v2.0 → North Star)

Both Marp decks restructured to 10 main + 6 appendix slides:

PW deck (17 slides):
1. Title
2. The Problem & The North Star (anti-goals moved to slide 3)
3. Where ACDL Sits in Your World (NEW — scope boundary, infra only)
4. The Contract-Driven Model (image: removed, infra inputs instead)
5. The End-to-End Flow
6. Zero-Trust by Default
7. Safety is Computed (NEW confidence signal diagram)
8. Security by Construction
9. Accountability & Audit (NEW attestation flow diagram, QA clarification,
   badge reclassification: dev=Testing, qa/prod/dr=Planned)
10. Testing vs. Planned (summary, full inventory in appendix)
11. The Vision Realized
+ Appendix: TOC, Platform-Managed Environments, Observability, Road to
  North Star, Full Inventory, Glossary

DX deck (16 slides):
1. Title
2. Where ACDL Sits in Your World (REPLACES Two Consumer Surfaces — scope
   boundary with both consumer paths)
3. The Contract — The Entire Consumer Surface (image: removed)
4. The Developer Feedback Loop
5. Versioned, Predictable Releases
6. Friendly Onboarding
7. Safe Promotion Path (NEW promotion journey diagram, rising bar
   annotated: dev=Testing, qa/prod/dr=Planned)
8. Safe Decommission
9. Self-Service Module Catalog
10. The Desired Outcomes
+ Appendix: TOC, Citizen Developer Experience, No Platform Code, Local
  Reproducibility, Road to North Star, Glossary

Story arc: every slide has an italic 'Story beat' line connecting it to
the narrative progression.

Scope clarification: ACDL is infrastructure only. Upstream is anything
(IDE, agentic SDLC, citizen dev vibe coding). ACDL provisions and governs
AWS resources; application deployment is upstream. Contract examples now
show infrastructure inputs (cpu, memory, desired_count, port) not image:.

QA attestation reclassification: 'Design tested' → 'Planned'. QA attests
to infrastructure readiness (contract + Terraform plan + evidence), not
application code. Dev is autonomous (Testing); qa/prod/dr are Planned.

Road to the North Star: phased timeline (v1.0 → v1.9 → v1.10 → v2.0 →
North Star), annotated 'proposed phasing, not formally planned.'

Also: scripts/sync_to_gl.sh added (GitLab mirror sync utility).
