Summary

• Align the C++ test naming convention with llama.cpp: rename all 24 test source files and corresponding executable/helper-library targets to test-*.
• Rename all CTest cases to test-*, including parametrized cases, and update their dependency references.
• Update Python callers, usage messages, and documentation for the renamed binaries. Keep Python module/script names, helper headers, fixtures, and test behavior unchanged.

Verification

• Linux Release static build with system ICU: 35/35 CTest cases passed.
• Linux Release shared build with system ICU: 34/34 CTest cases passed (the allocation test is static-only).
• Verified that every registered case in both builds has a unique test-* name.
• Parsed all 66 Python test/helper scripts, checked CMake source/script paths, and searched for stale source/target references.
• Independent rename-focused review: no findings.
• git diff --check passed.

Optional model-parity suites and GPU backends were not executed locally.
