Pull request overview

Adds a new bootdev local-test command to run a local cli.yaml manifest through the existing CLI/HTTP check runner and render the results, plus introduces local-side grading logic to simulate submission outcomes.

Changes:

• Add local-test Cobra command that loads a local manifest, runs checks, and simulates grading.
• Add YAML tags to client.CLIData and related structs to support unmarshalling local manifests.
• Introduce checks/local.go for evaluating results and producing a LessonSubmissionEvent, with tests covering the new behavior.
