The shared VCR BeforeSave hook scrubs every other header-auth provider's key
(X-Api-Key, Api-Key, Signoz-Api-Key, X-Auth-Token) but was not updated for
Dotfile, so re-recording testdata/dotfile.yaml with a real X-DOTFILE-API-KEY
would persist the key into the committed cassette. Delete the canonicalized
X-Dotfile-Api-Key header alongside the others.
