Description

• Add originalSource field to BundleOptions interface to provide bundlers with the unfiltered asset source path
• Pass originalSource (the real asset location before exclusions) alongside source (filtered copy) when calling bundler.bundle()
• Forward originalSource through ChainBundler to all bundler legs
• Update AssetStaging to resolve and pass the original sourcePath as originalSource
• Add tests verifying bundlers receive correct originalSource when exclusions are configured
• Enables bundlers to resolve node_modules, lockfiles, and symlinks relative to the asset's actual location instead of filtered scratch directories
