chore: update claude-code-base-action to v0.0.31

- Add fallback_model input to action.yml matching claude-code-base-action
- Pass fallback_model through to the base action
- Document the new input in README.md inputs table
- Enables automatic fallback when primary model is unavailable

+
+I can see the debug print statement that needs to be removed. Let me fix this by editing the file.
+
+### 🔧 `Edit`
+
+**Parameters:**
+```json
+{
+  "file_path": "/path/to/sample/file.py",
+  "old_string": "def example_function():\n    print(\"Debug message\")  # This should be removed\n    return \"Hello World\"",
+  "new_string": "def example_function():\n    return \"Hello World\""
+}
+```
+
+**→** File successfully edited. The debug print statement has been removed.
+
+*Token usage: 200 input, 50 output*
+
+---
+
+Perfect! I've successfully removed the debug print statement from the function. Let me now create a pull request comment to document this change.
+
+### 🔧 `mcp__github__add_pull_request_review_comment`
+
+**Parameters:**
+```json
+{
+  "owner": "example-org",
+  "repo": "example-repo",
+  "pull_number": 123,
+  "body": "Removed debug print statement as requested.",
+  "commit_id": "abc123def456",
+  "path": "sample/file.py",
+  "line": 2
+}
+```
+
+**→** Successfully posted review comment to PR #123
+
+*Token usage: 150 input, 80 output*
+
+---
+
+Great! I've successfully completed the requested task:
+
+1. ✅ Located the debug print statement in the file
+2. ✅ Removed the print statement while preserving the function logic
+3. ✅ Added a review comment documenting the change
+
+The debug print statement has been removed as requested by the reviewers.
+
+*Token usage: 180 input, 60 output*
+
+---
+
+## ✅ Final Result
+
+Successfully removed debug print statement from file and added review comment to document the change.
