适配v0.26.1

Update endpoints and metadata to match newer memos backend and record new maintainer.

- js/oper.js: switch upload endpoint to api/v1/attachments; replace auth/status POST with auth/me GET and adapt response parsing to response.user.name; stop using user-scoped memo endpoints and use api/v1/memos for tag/search/random requests; fix memo link path to /memos/{uid}.
- manifest.json: bump extension version to 2026.02.22 and update homepage_url to the GitHub repo.
- README.md: add maintainer note, compatibility (v0.26.1) and a collapsible details block.

These changes align the extension with backend API changes and mark the new maintenance status.
