fixes False positive with test builder pattern

[kunwardeep]

Issue: #50

[Copilot]

Pull Request Overview

This PR fixes a false positive issue in the paralleltest linter where test functions using builder patterns to generate test functions were incorrectly flagged as missing parallel calls, even when the returned functions properly called t.Parallel().

• Added support for analyzing function calls that return test functions (builder pattern)
• Enhanced the analyzer to inspect returned function literals for t.Parallel() calls
• Added comprehensive test cases covering both compliant and non-compliant builder patterns

This early return check is redundant since the same condition is checked at line 306 with return !hasParallel. The early return here prevents unnecessary traversal once parallel is found, but the logic at line 306 should be return true to continue inspection when parallel is not found.

Suggested change

	if hasParallel {
	return false
	}
