fix(claude): update spoofed cli version to 2.1.280 to support Opus 5.5

Browse Source 
Anthropic's newly released Claude Opus 5.5 model strictly requires
claude-cli version 2.1.280 or newer. Spoofing the older 2.1.258
version results in an HTTP 400 `claude_code_version_too_old` error.

This commit updates the hardcoded `CLAUDE_CLI_VERSION` in
`open-sse/providers/shared.js` and aligns the corresponding unit
tests and baselines to bypass Anthropic's version gating.
