#20261: docs: update claude-max-api-proxy to maintained fork

Closes #20260 ## Summary - Update GitHub and Issues links in the claude-max-api-proxy documentation to point to [wende/claude-max-api-proxy](https://github.com/wende/claude-max-api-proxy), an actively maintained fork - The original repo ([atalovesyou/claude-max-api-proxy](https://github.com/atalovesyou/claude-max-api-proxy)) is no longer maintained and has known broken behavior (e.g. `[object Object]` responses due to improper serialization) - The fork includes community fixes for OpenAI format handling, multi-modal content, streaming, and tool call support - Historical references in CHANGELOG.md, README contributors, and clawtributors-map.json are intentionally left unchanged See discussion of the issues: https://github.com/atalovesyou/claude-max-api-proxy/issues/2 ## Test plan - [ ] Verify links in `docs/providers/claude-max-api-proxy.md` resolve correctly - [ ] Verify links in `docs/zh-CN/providers/claude-max-api-proxy.md` resolve correctly <!-- greptile_comment --> <h3>Greptile Summary</h3> Updates the GitHub and Issues links in both English and Chinese `claude-max-api-proxy` documentation files to point to `wende/claude-max-api-proxy`, an actively maintained fork. The original repository (`atalovesyou/claude-max-api-proxy`) is unmaintained and has known bugs. - Two URL substitutions in `docs/providers/claude-max-api-proxy.md` (GitHub + Issues links) - Two URL substitutions in `docs/zh-CN/providers/claude-max-api-proxy.md` (GitHub + Issues links) - No remaining references to the old repository in documentation; historical attribution in CHANGELOG, README contributors, and clawtributors-map is correctly preserved - No issues found <h3>Confidence Score: 5/5</h3> - This PR is safe to merge — it only updates two documentation URLs with no code changes. - The change is limited to updating four URLs (two per file) in documentation markdown files. No code, configuration, or logic is affected. The old repository references are fully replaced in documentation, while historical attribution entries are correctly preserved. Both files follow their existing formatting conventions. - No files require special attention. _{Last reviewed commit: 059d2e2} <!-- greptile_other_comments_section --> _{(2/5) Greptile learns from your feedback when you react with thumbs up/down!} <!-- /greptile_comment -->
