Subject: [PATCH 1/7] feat: add Groovy/Spock test file pattern support

Extend test file discovery to support .groovy files alongside .java.
Adds GROOVY_TEST_FILE_PATTERNS and GROOVY_TEST_FILE_REGEXES to the
patterns module and updates file_checker to strip .groovy extension
when matching test class name patterns.

Fixes #194

Subject: [PATCH 2/7] test: add Groovy unit tests and E2E test suite

Add unit tests for Groovy file pattern matching in file_checker:
- Groovy test file discovery (*Spec.groovy, *Test.groovy, *IT.groovy)
- Groovy non-test file exclusion
- Groovy files in main folder exclusion

Add E2E test suite (groovy_support_spec.lua) with complete Maven+Groovy fixture:
- CalculatorSpec.groovy - Spock specification tests (4 tests)
- UserServiceTest.groovy - Groovy JUnit tests (4 tests, 1 intentional failure)
- Tests verify discovery, execution, and pass/fail reporting

Fixture includes pom.xml with GMavenPlus plugin, Spock dependency,
and source files for both Java and Groovy tests.

Fixes #194

Subject: [PATCH 3/7] ci: run groovy fixture tests in E2E pipeline

Update run-all.sh to:
- Discover and run all fixtures automatically (not just maven-simple)
- Find both .java and .groovy test files in src/test/java and src/test/groovy
- Support *Test, *Spec, and *IT naming conventions for both languages

Update run.lua to:
- Extract expected class name from .groovy files (not just .java)
- Derive snapshot file names for .groovy test files

Update minimal_init.lua to:
- Include tests/e2e/*_spec.lua in test collection (previously only tests/unit)
- Ensures groovy_support_spec.lua and full_workflow_spec.lua run in CI

Fixes #194

Subject: [PATCH 7/7] test: add Groovy position discovery tests

Add unit tests for Groovy position discovery:
- Spock feature methods with string literal names (def "test"())
- JUnit-style annotated methods in Groovy (@Test)

Tests skip gracefully when Groovy treesitter parser is not compiled.

Fixes #194
