Generate and publish assessment artifacts, then clean modernization context

[Copilot]

This change runs the repository assessment workflow and checks in the generated assessment artifacts under the required .github/modernize/assessment path. It also performs the required post-run cleanup by removing temporary modernization context files.

• Assessment outputs

  • Added versioned assessment report:
    • .github/modernize/assessment/reports/report-20260520055214/report.json
  • Preserved generated AppCAT runtime artifacts under .github/modernize/appcat/ needed by this run.

• Post-assessment cleanup

  • Executed the context cleanup flow and removed .github/modernize/ccacontext.
  • Deleted:
    • .github/modernize/ccacontext/.ccaskills
    • .github/modernize/ccacontext/cleanup.sh

• Repository state alignment for review

  • Force-included generated files under .github/modernize so assessment artifacts are present in the PR as required.

.github/modernize/assessment/reports/report-20260520055214/report.json
.github/modernize/appcat/result/analysis.log
.github/modernize/appcat/result/shim.log

Original prompt

Task: Assess the application

Run core assessment

Use the 'assessment' skill to analyze the application and generate the assessment report.
This skill runs AppCAT (Azure Migrate application and code assessment) to detect migration issues.

Commit and PR instructions

Before committing, use 'git add -f .github/modernize/assessment' to force-add the assessment outputs under that directory so they are included in the pull request even if a .gitignore file would otherwise exclude them.. Only the files that were actually generated will be staged.

When creating the PR, propose a proper title, but DO NOT contain any tool/tech stack on it, e.g. 'Assessing project with AppCAT' is not good as AppCAT is one of the assessing tool.
