Problem: the CSES API token was packed into the git credential
password field using a tab separator. This leaked session state
into the credential layer and broke with helpers that don't
differentiate by path (e.g. `cache`).
Solution: store the CSES token via `save_platform_cookies`/
`load_platform_cookies`, the same mechanism every other platform
uses for session state. Remove all token logic from
`git_credential.lua`. Git credential now stores only
`{username, password}` uniformly for all platforms.
