Pull Request: Optimize Project Discovery and File Triage to Prevent Hangs

1. Overview

This PR addresses issue #150, where the /conductor:setup command could hang in large repositories (especially those without a .gitignore) due to aggressive, recursive file system scans during the project discovery phase.

2. Problem Statement

The previous implementation of the project discovery protocol did not have strict depth limits for file system scans. In large, monolithic, or deeply nested repositories, this could cause the agent to attempt to list or analyze thousands of files, leading to timeouts and a perceived "hang" in the command.

3. Proposed Solution & Detailed Changes

File Path	Change Category	Description of Change
commands/conductor/setup.toml	Performance / Logic	Depth-Limited Discovery: Implemented a maxdepth 2 limit for the initial project maturity detection (Brownfield/Greenfield indicators).
commands/conductor/setup.toml	Performance / Portability	Efficient File Triage: Updated the file triage protocol to use more efficient find commands with pruning and added PowerShell-optimized Get-ChildItem -Depth for Windows users.
commands/conductor/setup.toml	Robustness	Instructional Guardrails: Added explicit warnings to the agent's protocol to avoid unbounded recursive listings in large projects.

4. Technical Rationale

• Performance: Limiting the depth of initial scans dramatically reduces the I/O load and processing time for large repositories without sacrificing the accuracy of the maturity detection.
• Cross-Platform Support: By providing specific PowerShell commands for Windows environments, we ensure that performance optimizations are effective across all supported operating systems.
• Stability: These changes provide the agent with clearer guardrails, reducing the risk of non-deterministic behavior in complex project structures.

5. Verification Performed

• Logic Audit: Reviewed the updated .toml prompt to ensure the new constraints are clear and correctly implemented.
• Command Verification: Confirmed that the proposed shell commands follow best practices for performance and cross-platform compatibility.

6. Checklist

• Changes address the specific performance concerns raised in issue refactor(conductor): refine Plan Mode terminology to avoid confusion with native CLI mode #150.
• No sensitive information or credentials are included.
• Commit messages follow the type(scope): description format.
• Verified that no regressions were introduced in existing setup flows.
