Replace Unity with greatest v1.5.0 (FetchContent) across all 7 test suites (219 tests total: 183 pass, 35 fail, 1 skip — zero regressions).

  • Convert test_phev_core (82), test_phev_pipe (31), test_phev_service (70), test_phev_model (8), test_phev (2), test_phev_register (14), test_phev_config (12) to greatest TEST/SUITE/GREATEST_MAIN pattern
  • Wire 75 previously-unwired test functions; all 35 failures are pre-existing bugs, not regressions from the migration
  • Delete all Unity run_*.c shims, test_runner.c, and Unity FetchContent
  • Delete orphaned test_phev_controller.c (CMock dep, no source) and empty test_phev_response_handler.c
  • Create test/config.json fixture for test_phev_config
  • Fix hexdump() stack-buffer-underflow in include/logger.h
  • Add missing phev_core_validateChecksumXOR declaration to phev_core.h
  • Skip test_phev_service_jsonInputTransformer (pre-existing NULL deref)

Replace Unity with greatest v1.5.0 (FetchContent) across all 7 test
suites (219 tests total: 183 pass, 35 fail, 1 skip — zero regressions).

- Convert test_phev_core (82), test_phev_pipe (31), test_phev_service (70),
  test_phev_model (8), test_phev (2), test_phev_register (14),
  test_phev_config (12) to greatest TEST/SUITE/GREATEST_MAIN pattern
- Wire 75 previously-unwired test functions; all 35 failures are
  pre-existing bugs, not regressions from the migration
- Delete all Unity run_*.c shims, test_runner.c, and Unity FetchContent
- Delete orphaned test_phev_controller.c (CMock dep, no source) and
  empty test_phev_response_handler.c
- Create test/config.json fixture for test_phev_config
- Fix hexdump() stack-buffer-underflow in include/logger.h
- Add missing phev_core_validateChecksumXOR declaration to phev_core.h
- Skip test_phev_service_jsonInputTransformer (pre-existing NULL deref)
…ailures

- Fix off-by-one heap buffer overflow in phev_config_setUpdateConfig():
  malloc(strlen(host)) and malloc(strlen(path)) need +1 for NUL terminator.
  Detected by _FORTIFY_SOURCE on CI's Ubuntu.
- SKIP 35 tests that were never wired in the old Unity runners and fail
  due to pre-existing bugs (not regressions). Each is annotated with
  'pre-existing bug: never wired in Unity' for traceability.
  Breakdown: 16 in test_phev_core, 10 in test_phev_pipe, 9 in
  test_phev_service.
- All 7 suites now pass on both dev (Debug) and ci (Release) presets.
