[Sprint 19] Repair Aspire startup on new machine

[mpaulosky]

Objective

Restore full build and Aspire orchestration functionality on new development machine after initial environment setup failure.

Description

Development environment on new machine is broken:

• Aspire service failed to start
• Build or local testing may be blocked
• Full environment repair is needed before feature work can continue

Scope

1. Diagnose the Aspire startup failure
2. Verify required dependencies (.NET SDK, Docker, MongoDB/tooling)
3. Run the authoritative repair flow from .github/prompts/build-repair.prompt.md
4. Verify Aspire/AppHost starts cleanly
5. Document the repair steps and fixes

Acceptance Criteria

• Aspire AppHost starts without errors
• Orchestrated services come up cleanly
• dotnet build --no-restore succeeds with zero errors and zero warnings
• All required local test suites pass
• The repair steps and findings are documented in build-log.txt
• Local pre-push validation is working

Notes

• This is a blocking issue for new-machine setup
• Zero-tolerance build/test cleanliness applies
• Docker may be required for AppHost/integration coverage
