adding-ai-agent-rendering-system

Add a new AI agent rendering system to Packmind, supporting both single-file (like AGENTS.md) and multi-file (like Cursor/Continue) patterns, including type definitions, deployer implementation, registry registration, frontend UI integration, documentation updates, and comprehensive tests following Packmind test standards. ## When to Use * When adding support for a new AI coding assistant (e.g., Continue, Cursor, Claude Code, GitHub Copilot, OpenCode) * When implementing a new rendering format for standards and recipes distribution * When extending Packmind to support additional AI agent integrations * When creating a new deployer that follows the ICodingAgentDeployer interface ## Prerequisites — Gather from User Before proceeding, the following information **must** be known. If any of these are unclear or not provided, **prompt the user** to clarify before starting implementation. 1. **What is the agent's identifier key and display name?** - The **identifier key** is the snake_case string used in code (`CodingAgent` type, `CodingAgents` record, `AGENT_FILE_PATHS`, etc.). Examples: `opencode`, `gitlab_duo`, `continue`, `agents_md`. - The **display name** is the human-readable label shown in the frontend UI and CLI. Examples: `OpenCode`, `GitLab Duo`, `Continue`, `AGENTS.md`. - Both values are reused consistently across all steps (type definitions, deployer class, registry, frontend labels, CLI display names, documentation). 2. **In which directories will Sta...
