📝 Walkthrough

Walkthrough

The duplicate-code visitor now ignores files outside the configured analysis context root. A regression test confirms that such files are not indexed or reported.

Filter external files before duplicate analysis lib/src/lints/avoid_duplicate_code/visitors/avoid_duplicate_code_visitor.dart, test/src/lints/avoid_duplicate_code/avoid_duplicate_code_rule_test.dart	The visitor uses PathUtils.isWithinOrEqual to skip files outside the context root. The regression test verifies that the global registry remains empty.
