Harden all three fetch handlers (dependabot/code-scanning/secret-scanning) to log only the repo identity plus the exception class name (`type(exc).__name__`) — never the exception object or response status. Keeps useful diagnostics (which repo, which error class) without routing session/response-derived data to the log.
