Description

## Problem
Orchestrator sends reviewer messages like "two tickets need review" which breaks the **one task at a time** principle. Reviewers should be assigned a SINGLE ticket to work on, not given a list to choose from.

## Current Behavior (Wrong)
```
Orchestrator → Reviewer: "Two tickets need review: #101 and #102"
```
This creates ambiguity - which one should the reviewer work on first?

## Expected Behavior (Correct)
```
Orchestrator → Reviewer: "Work on ticket #101"
[After #101 done]
Orchestrator → Reviewer: "Work on ticket #102"
```

## Files to Check
- `app/jobs/orchestrator_ping_job.rb` - The coordination logic
- Agent logic that picks tickets for reviewers

## Fix Required
When orchestrator assigns work to reviewers:
1. Pick ONE available reviewer
2. Pick ONE `pending_audit` ticket
3. Send specific message: `"Work on ticket #<id>"`
4. Repeat for next ticket/reviewer pair

## Acceptance Criteria
- Reviewers receive ONE ticket assignment at a time
- Message format is clear: "Work on ticket #X"
- No batching of multiple tickets in one message
- Orchestrator iterates through tickets one-by-one, not in batches
