url.Parse treats a Windows absolute path such as C:\charts\mychart as
having scheme "c", so sanitizeChartSource re-encoded it (e.g. the drive
letter was lowercased and separators could be percent-escaped), producing
a misleading SOURCE value for local installs/upgrades.
Gate sanitization on the parsed URL having a host component, so only real
repository URLs (scheme://host/...) are rewritten while local filesystem
paths and chart references are returned unchanged. Add regression tests
covering Windows (back- and forward-slash) and absolute unix paths.
