test: improve coverage for MatchStrategy

This commit adds a new unit test suite, `MatchStrategyTest`, to explicitly
verify the behavior of the `FileMatchCollector` instances produced by
`MatchStrategy.ALL_MATCHES` and `MatchStrategy.ANY_MATCH`. It tests their
core branch logic regarding the termination condition (`searchIsOver()`).
These tests strictly utilize standard JUnit 4 APIs and Mockito for dependency
isolation, and maintain full compatibility with the existing test infrastructure.
