Add migration assessment artifacts and remove temporary assessment context

[Copilot]

This PR runs the repository assessment workflow and checks in the generated, versioned assessment report under .github/modernize/assessment. It also applies the required post-run cleanup by removing transient assessment context content from .github/modernize.

• Assessment output captured

  • Added the generated report at:
    • .github/modernize/assessment/reports/report-20260521033925/report.json
  • This preserves the assessment result as a versioned artifact for review.

• Required cleanup applied

  • Removed .github/modernize/ccacontext after executing its cleanup script.
  • Removed temporary skill/context files introduced for the assessment job.

• Force-include behavior respected

  • Assessment artifacts under .github/modernize/assessment were force-added so generated outputs are included even if ignored by default.

• Artifact layout

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.
