docs: add OpenCode Anthropic OAuth plugin to README

[marcusquinn]

Summary

Documents the opencode-anthropic-auth plugin in the README alongside the existing Antigravity OAuth plugin documentation.

Changes

• Documented authentication methods (Claude Pro/Max OAuth, Create API Key, Manual)
• Highlighted zero-cost benefit for Claude subscribers
• Listed available models and beta features
• Linked to plugin repository and internal documentation

Context

The setup.sh script already installs this plugin (v0.0.8), but it wasn't documented in the README. This brings the README up to date with the actual installation.

Code Review

This pull request adds documentation for the opencode-anthropic-auth plugin to the README.md file. The new section clearly explains the plugin's purpose, benefits, and usage. The changes are well-structured and informative. I have one suggestion to improve the clarity of the available models list by removing a potentially confusing entry.
