Fix Claude Code action max_turns limit for PR reviews

Problem

Claude Code action is hitting the max_turns: 5 limit before completing PR reviews in the web-experience project. The action posts the initial task list but never provides actual review feedback, leaving all checkboxes empty.

From the action logs:

"subtype": "error_max_turns"
"num_turns": 5

Claude runs out of turns after reading the changed files but before writing and posting the review feedback.

Solution

Increase max_turns from 5 to 10 in the reusable workflow. This may need further adjustment if 10 turns proves insufficient for larger PRs.

Why this change is needed

For PR reviews, Claude typically needs:

• 1 turn: Post initial task list
• 3-4 turns: Read each changed file
• 2-3 turns: Analyse code and write comprehensive review
• 1 turn: Update comment with final review feedback

5 turns only allows file reading, not the actual review analysis and posting.

Impact

• PR reviews will now complete successfully with actual feedback
• No impact on simpler tasks that don't need as many turns
• Slight increase in action runtime for complex reviews (but they'll actually work)
• May need further tuning based on PR complexity

Note that I have added to the template as I reckon 5 is too small for any PR. We can do the tweaking higher in web experience if we still find 10 to be insufficient
