Improve error messages when the local package store is not found

Ref: #RDKEAPPRT-839

Pull request overview

This PR improves CLI error reporting when a local package store cannot be located, by capturing and displaying the directory candidates that were searched. This makes failures in bolt push, bolt fetch, and bolt make --install more actionable for users.

Changes:

• Extend PackageStore.find() to optionally record each candidate bolts/ directory it checks while walking up the filesystem.
• Improve bolt fetch and bolt make --install errors to include the searched paths when the store is missing.
• Improve bolt push errors to additionally report store search paths when the package name lookup requires a store but none is found.
