```

## From README

Phase 0: Intent Message Reporting Action: Before proceeding, immediately tell the user: "I will upgrade Play Billing Library to the latest version." Phase 1: Discovery \\& Situational Awareness Primary Check (Build Version) : Locate the project's billing dependency (e.g., com.android.billingclient:billing) in build.gradle, build.gradle.kts, or libs.versions.toml. Initial Compilation Test: Attempt to sync and build the project immediately. Fallback Discovery (Effective Version) : Trigger: Only if the build fails immediately, scan the source code for deprecated artifacts. Logic : The presence of deprecated APIs indicates the "Effective Version" ---defined as the version where those specific APIs were last available, not when they were introduced. Example : If SkuDetails is present, treat the baseline as PBL v7 or earlier (regardless of the version string in build.gradle).
