Greptile Summary

This PR adds documentation for PR conventions to the AGENTS.md file and creates a CLAUDE.md symlink to improve AI agent compatibility. The changes are focused on helping AI coding assistants understand the repository's contribution standards.

The main change adds a "PR Conventions" section to AGENTS.md that specifies two key requirements: PR titles must follow Conventional Commits format (e.g., feat: ...) and are enforced by .github/workflows/pr-labeller.yml, and PR descriptions should follow the template in .github/pull_request_template.md. This documentation follows the emerging agents.md standard for providing concise development instructions to AI agents.

Additionally, a CLAUDE.md symlink is created that points to AGENTS.md. This addresses compatibility with Claude Code, which doesn't yet support the AGENTS.md standard but can read CLAUDE.md files. The symlink approach maintains a single source of truth while ensuring broader AI agent compatibility.

These changes integrate well with the existing codebase infrastructure - they reference actual workflow files and templates that already exist in the repository, providing actionable guidance that's tied to enforced automation. The AGENTS.md file was already present in the repository (as shown in the file listing) and serves as documentation specifically for AI development tools working with the Daft framework.
