#14630 42df9bb Thanks @penalosa! - Extract the Cloudflare CLI auth layer into a product-agnostic @cloudflare/workers-auth core
The OAuth login/logout/refresh, credential storage, config cache, and account-selection machinery is now shared behind an AuthProduct descriptor, with a thin per-CLI entrypoint on top. @cloudflare/workers-auth/wrangler (createWranglerAuth) preserves wrangler's existing behaviour, and a new @cloudflare/workers-auth/cf (createCfAuth) adds the cf CLI: its own OAuth app registration (client id, callback port, branded consent pages, scoped-token-only auth), a dedicated scope catalog, JSON config files under ~/.config/cloudflare, and an isolated config-cache namespace so cf login/logout never purges wrangler's cache.
As part of the extraction, @cloudflare/workers-utils now exports the shared createConfigCache (with a namespace option), openInBrowser, and the isInteractive / isNonInteractiveOrCI / isCI TTY-and-CI detection helpers (each taking the caller's logger as a parameter rather than relying on a singleton). These read a bundled ci-info, so consumers that need to fake CI in their tests should mock this package's helpers rather than ci-info directly.
