fix(create-milestones): clarify loop structure for assigning issues

Restructure steps 7-8 to be clearer and more efficient:
- Merged "Assign Issues" and "Apply Labels" into single step
- Explicit nested loop structure: milestone → issues in that milestone
- Process one milestone at a time
- Combine milestone assignment + labels in single tea command
- Added clear examples
- Prevents confusion about looping and when to move on

Before: Separate loops for milestone assignment and label application
After: Single pass through milestones, process all issues per milestone

-For each issue in each milestone:
+**For each milestone, process all its issues:**
 
 ```bash
-tea issues edit <issue-number> --milestone "<milestone-title>"
+# For each milestone:
+for milestone in milestones:
+  # For each issue in this milestone:
+  for issue in milestone.issues:
+    # Combine milestone assignment + labels in single command
+    tea issues edit <issue-number> \
+      --milestone "<milestone-title>" \
+      --labels "<existing-labels>,<value-label>,<risk-label-if-applicable>"
 ```
 
-### 8. Apply Value/Risk Labels
+**Example:**
-
-For each issue:
-
 ```bash
-tea issues edit <issue-number> --labels "<existing-labels>,<value-label>"
+# Issue #42 in "Customer can register and authenticate" milestone
+tea issues edit 42 \
+  --milestone "Customer can register and authenticate" \
+  --labels "bounded-context/auth,value/high"
 
-# If has risk
+# Issue #43 with risk
-tea issues edit <issue-number> --labels "<existing-labels>,<value-label>,risk/high"
+tea issues edit 43 \
+  --milestone "Customer can register and authenticate" \
+  --labels "bounded-context/auth,value/high,risk/high"
 ```
 
-**Preserve existing labels** (bounded-context, capability, etc.)
+**Important:**
+- Process one milestone at a time, all issues in that milestone
+- Preserve existing labels (bounded-context, capability, etc.)
+- Add value label for all issues
+- Add risk/high only if issue has technical risk
+- Combine milestone + labels in single `tea issues edit` command (efficient)
