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()`)
by invoking `acceptFile()` and verifying the boolean return values and the
size of the collected results. These tests strictly utilize standard JUnit 4
APIs and lightweight Mockito stubs for dependency isolation.
