Add script to backfill duplicate comments for old issues

Creates a script that identifies old issues without duplicate detection comments and triggers the existing claude-dedupe-issues workflow for each one. This helps ensure historical issues get proper duplicate detection coverage.

Features:
- Scans issues from configurable time period (default 30 days)
- Skips issues that already have duplicate detection comments
- Triggers existing workflow instead of duplicating logic
- Includes dry-run mode and rate limiting for safety

 # Changelog
 
+## 1.0.71
+
+- Background commands: (Ctrl-b) to run any Bash command in the background so Claude can keep working (great for dev servers, tailing logs, etc.)
+- Customizable status line: add your terminal prompt to Claude Code with /statusline
+
+## 1.0.70
+
+- Performance: Optimized message rendering for better performance with large contexts
+- Windows: Fixed native file search, ripgrep, and subagent functionality
+- Added support for @-mentions in slash command arguments

+- Upgraded Opus to version 4.1
+
+## 1.0.68
+
+- Fix incorrect model names being used for certain commands like `/pr-comments`

+- Enhanced /doctor command with CLAUDE.md and MCP tool context for self-serve debugging
+- SDK: Added canUseTool callback support for tool confirmation
+- Added `disableAllHooks` setting
+- Improved file suggestions performance in large repos
+
+## 1.0.65
+
+- IDE: Fixed connection stability issues and error handling for diagnostics
+- Windows: Fixed shell environment setup for users without .bashrc files
+
+## 1.0.64
+
+- Agents: Added model customization support - you can now specify which model an agent should use
+- Agents: Fixed unintended access to the recursive agent tool
+- Hooks: Added systemMessage field to hook JSON output for displaying warnings and context
+- SDK: Fixed user input tracking across multi-turn conversations
+- Added hidden files to file search and @-mention suggestions
+
+## 1.0.63
+
+- Windows: Fixed file search, @agent mentions, and custom slash commands functionality
+
 ## 1.0.62
 
 - Added @-mention support with typeahead for custom agents. @<your-custom-agent> to invoke it
