Add Claude Code GitHub Actions workflows

[jnasbyupgrade]

Adds the Claude Code GitHub Actions workflows: claude.yml (@claude mentions) and claude-code-review.yml (auto-review on PRs from the jnasbyupgrade fork via pull_request_target, gated to that fork). Requires the CLAUDE_CODE_OAUTH_TOKEN secret on this repo and the Claude GitHub App granted access. Part of enabling Claude Code review across the postgresql-extensions repos.
