#10577: Ask Sage provider integration

**Note:** This PR was assisted by Claude. ## Description This PR integrates Ask Sage as a model provider for OpenClaw, specifically US Government and non-gov allowed Claude models: 3.5 Sonnet gov, 4 Sonnet gov, and 4.5 Sonnet gov, 4 Sonnet, 4 Opus, 4.5 Haiku, 4.5 Sonnet, 4.5 Opus, and 4.6 Opus. Relevant markdown documentation has also been created, along with some bash scripts and Dockerfiles for testing the integration in a sandboxed environment, instead of on a local machine. ## Testing This PR has been tested with the newly created Docker/bash tests, and the OpenClaw provided tests within a Docker container. ## Session Log When running `bash scripts/test-asksage-complete.sh`, here is part of the output showing that it is able to connect to the Ask Sage models ``` Running agent...

There is also an async/await inconsistency in the new credential setter that could cause onboarding to proceed before credentials are persisted if the underlying storage is async. - src/agents/asksage-models.ts, src/commands/onboard-auth.credentials.ts <!-- greptile_other_comments_section --> _{(2/5) Greptile learns from your feedback when you react with thumbs up/down!} <!-- /greptile_comment -->
