Multiple agents execution (planning, implementation, review)

[tomzx]

Background

The goal is to enable the system to execute multiple agents in parallel for different phases of software development, such as planning, implementation, and review. This will allow for more sophisticated agentic workflows where each agent specializes in a particular phase.

Acceptance Criteria

• Design a workflow that allows parallel execution of multiple agents on the same task
• Implement a mechanism to collect and generalize what was produced by the various agents
• Ensure that each agent can operate independently (e.g., worktree isolation)
• Update documentation (AGENTS.md or similar) to explain how to use the multiple agents execution feature
