ci: move @claude comment workflow to claude-code-action v1 and pin model

[ymc9]

Summary

@claude comment triggers have been failing (e.g. this run) with:

API Error: 404 {"type":"not_found_error","message":"model: claude-sonnet-4-20250514"}

.github/workflows/claude.yml still used anthropics/claude-code-action@beta, whose default model has been retired. The automatic PR review workflow already runs on @v1 and works.

Changes

• claude.yml: switch to anthropics/claude-code-action@v1
• Both workflows: pin the model via claude_args: "--model claude-sonnet-5" (v1 has no model input) so a retired default cannot break them again

🤖 Generated with Claude Code

Summary by CodeRabbit

• Chores
  • Updated automated development workflows to use a stable action release.
  • Standardized workflow runs on a fixed Claude Sonnet 5 model for more consistent results.
