fix: replace non-existent full_integration_test with existing comprehensive tests

- Fix CI failure in Final Integration job where full_integration_test target didn't exist
- Replace with 'cargo test test_comprehensive --all-features' which runs:
  - test_comprehensive_analysis in codeprism-analysis
  - test_comprehensive_regex_edge_cases in codeprism-core
  - test_comprehensive_recommendations in codeprism-lang-js
  - test_comprehensive_rust_analysis in codeprism-lang-rust
  - test_comprehensive_spec_performance and test_comprehensive_tool_coverage in mandrel-mcp-th

This provides thorough integration testing of the complete pipeline across all packages.

Resolves CI run 16639495800, job 47087377123 exit code 101 error.
