Subject: [PATCH] fix: pin create-github-app-token to immutable SHA

Pin actions/create-github-app-token to v3.2.0 commit SHA (bcd2ba49...) instead of mutable @v3 tag to prevent supply chain attacks where a compromised account could force-push malicious code to the tag. This eliminates the risk of secret leakage and malicious code execution in CI workflows.
