The OPENAI_CONTEXT_WINDOWS/OPENAI_MAX_OUTPUT_TOKENS tables only contained
the `github:copilot:<model>` namespaced form used when talking directly to
Copilot via /onboard-github. When OpenClaude is pointed at a LiteLLM proxy
(which routes Copilot using the standard `github_copilot/<model>` convention),
the lookup missed and fell back to the conservative 8k default — causing the
compaction loop to fire repeatedly on every tick and blocking requests
before they left the client with repeated "not in context window table"
warnings on stderr.
Mirror the 11 active Copilot models with LiteLLM-style keys in both tables.
No behavior change for users of /onboard-github since namespaced entries
remain untouched and `lookupByKey` picks exact matches first.
