OCR should optionally post its findings to the GitHub PR Issue

### Problem Statement

Ideally OCR is runnable from an action or remote service and it can post its findings to the GitHub PR it was triggered from. Even better would be providing inline code comments and suggestions.

### Proposed Solution

I imagine it'd be a decent amount of work to implement, but maybe not a huge amount with the github MCP providing the API.

### Alternatives Considered

_No response_

### Affected Area

Review Agent / LLM interaction, Output / Formatting

### Additional Context

_No response_

Start by locating the Review Agent / LLM interaction and Output / Formatting areas mentioned in the issue, then review how the GitHub MCP could access the pull request. Define the optional posting behavior and whether inline comments or suggestions are included. Done means OCR findings can be posted to the triggering GitHub PR, with any supported inline output clearly represented.
