Title
fix: only warn when no lockfile present (package-lock.json | npm-shrinkwrap.json) (#852)
Body
Summary: Avoid a misleading "PRO TIP" when an app has npm-shrinkwrap.json vendored. The buildpack should not warn about a missing package-lock.json if an equivalent lockfile exists.
Root cause: NoPackageLockTip() iterated lockfile names and emitted the tip on the first missing file instead of checking whether any supported lockfile exists.
Changes: Update NoPackageLockTip() in supply.go to check for any existing lockfile before warning and adjust the message to reference package-lock.json or npm-shrinkwrap.json (or yarn.lock for Yarn). Added unit tests in supply_test.go covering both the positive and negative cases.
Tests: Added unit tests for the NoPackageLockTip() behavior. CI should run the test suite; if you run locally you may see platform-specific issues building test binaries (I observed a macOS dyld build abort), but the code and tests are committed.
