**Tell us about your request**
AWS added a new selection type named "tagPatternList" to the ECR lifecycle rules several months ago. It works similar to "tagPrefixList" but with wildcards.
Please add tagPatternList support to the ECR lifecycle policy validator.

**Which service(s) is this request for?**
ECR

**Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?**
Currently it's not possible to create c7n policy with ECR lifecycle policy which contains rules with "tagPatternList" selector b.c. c7n ECR lifecycle policy validator doesn't know about it.

The issue identifies the ECR lifecycle policy validator as the entry point, but names no repository files or tests. Start by locating that validator and its existing tagPrefixList handling, then verify tagPatternList behavior against AWS ECR policy rules. Done means valid policies using tagPatternList pass validation without regressing existing selectors.
