[Docs] add Sprint2 presentation script

[SilverSupplier]

Summary

• Add a Sprint2 presentation script draft for slides 1 through 3.
• Keep the script in the submission docs area without changing source code or existing scripts.

Related Issue

• None (docs/policy-only PR)

Area

• Engine
• Domain
• Application
• Docs
• Build
• Analysis
• Chore

Architecture Check

• I kept the dependency direction application -> domain -> engine.
• I did not add Qt UI code to src/domain.
• I did not add domain or application dependencies to src/engine.
• I used src/ as the include root.

Docs-only change; no source dependencies or include paths were changed.

Verification

• cmake --preset windows-debug
• cmake --build --preset build-debug
• ctest --preset test-debug
• Not run (reason below)

Not run: docs-only markdown addition.

Risks / Follow-up

• Remaining slide scripts can be added in follow-up commits or PRs.
