A matching realpath does not make an excluded symlink spelling a discovered test. Compare differing path components, rejecting symlink aliases while preserving ordinary case and Unicode filesystem identity.
Validation: all 14 runner boundary tests pass, including excluded file/directory aliases, valid selections and no target execution.
Based on #2849.

Use exact discovered test identities, production MCP sessions and byte-exact setup backups. Add CLI signal cleanup coverage and independent Ghidra, Go and firmware verification assertions; prune redundant test configuration and preserve platform limits.
