Allow Bazel --test_filter to select tests when UNITY_USE_COMMAND_LINE_ARGS is enabled. Remarks: Avoid to include <stdlib.h>. Instead used extern ... . Maybe stdlib.h is more compatible.
Explain that Unity honors TESTBRIDGE_TEST_ONLY when UNITY_USE_COMMAND_LINE_ARGS is enabled and that UNITY_GETENV can be overridden to avoid <stdlib.h>.

Summary
Add Bazel test filtering support via TESTBRIDGE_TEST_ONLY when UNITY_USE_COMMAND_LINE_ARGS is enabled, plus core tests and docs.
Why
Bazel’s --test_filter sets TESTBRIDGE_TEST_ONLY. Unity previously ignored this, so single‑test runs were not possible.
What Changed
Support TESTBRIDGE_TEST_ONLY in UnityParseOptions
Add Unity core tests for env‑based filtering and CLI override
Document new behavior and note UNITY_GETENV override option
Update UnityChangeLog.md
Notes
Requires UNITY_USE_COMMAND_LINE_ARGS
