[codex] Optimize test framework flow

[Pluze]

Summary

• centralize build task selection metadata in a private buildfile catalog while preserving all existing build task names
• add runLabKitTests ListOnly mode plus project guardrails for task/docs/wrapper drift, focused task matching, default non-GUI selection, tags, and CI coverage policy
• move coverage out of the default PR CI path into manual/scheduled CI and namespace GitHub MATLAB logs by run name

Tests

• bash -n scripts/run_matlab_tests.sh
• bash scripts/run_matlab_tests.sh --help
• MATLAB_CMD=true bash scripts/run_matlab_tests.sh testProject
• bash scripts/run_matlab_tests.sh --suite exits 2 as expected
• scripts/run_matlab_tests.sh testProject
• scripts/run_matlab_tests.sh testUnit testIntegration
• scripts/run_matlab_tests.sh test
• scripts/run_matlab_tests.sh coverage
• scripts/run_matlab_tests.sh checkStyle
• git diff --check

Notes

• Coverage is intentionally no longer a default PR quality gate; manual and scheduled workflows still generate coverage artifacts.
• Interactive GUI workflow feel was not manually validated; this change only affects test orchestration and noninteractive checks.
