0.6.0 - 2026-06-16

auth: OAuth2 login now uses a remote copy-paste flow instead of a localhost callback server. The CLI prints an authorization URL with redirect_uri=https://sdk.cloud.google.com/applicationdefaultauthcode.html and token_usage=remote, then reads the pasted code from stdin. This works in headless/remote environments where a browser cannot reach a local callback port. (#54)

display output: Rich rendering for display_data output via a shared render_display_data() helper. HTML is converted with html2text and rendered as Markdown, following a text/markdown > text/html > text/plain priority; text/plain is wrapped with Text.from_ansi to preserve embedded ANSI escapes. Applied consistently across exec, console/repl, and automation call sites. (#58)

keep-alive: Replace the RuntimeService/KeepAliveAssignment RPC on colab.pa.googleapis.com with a Tunnel Frontend (TFE) HTTP ping (GET /tun/m/<endpoint>/keep-alive/ with X-Colab-Tunnel: Google) on colab.research.google.com, authenticated by the user's own bearer token. The old RPC required serviceusage consumer access to Colab's internal project and returned HTTP 403 USER_PROJECT_DENIED for every external user, causing their sessions to be idle-pruned within minutes. The TFE ping needs no project entitlement; because the VM often does not answer on this path, a ReadTimeout is treated as success while genuine HTTP errors propagate. (#14, #61)

Dead grpc-web client-registry / API-key code path and the now-irrelevant colaboratory-scope / pa.googleapis.com pre-flight remediation messaging, superseded by the TFE keep-alive ping. (#61)
