## Why
Endpoint protection products can interfere with Codex, but existing doctor reports do not identify them or explain which Codex exclusions need verification.
## What changed
- Detect supported endpoint protection products on macOS and Windows and add the results to the doctor environment report.
- Warn when detected products have unverified Codex exclusions, with product-specific remediation for CrowdStrike Falcon, BeyondTrust Privilege Management, Microsoft Defender, SentinelOne, and Jamf Protect.
- Distinguish complete, partial, and unavailable inspection results without requiring remediation when no product is detected.
## Testing
- Cover empty, unavailable, partial, single-product, and multi-product inspection results.
- Verify the structured JSON contract and human-readable report output.
