feat: add watch daemon with watching list mechanism

✨ New Feature: Watch Daemon
- Automatically monitor PRs and update Jira when merged
- Smart watching list: only track PRs created with qkflow
- Multi-repository support without configuration
- Intelligent scheduling (15min daytime, 2:00/6:00 night)
- Auto-start on login (launchd on macOS)
- Desktop notifications
- Auto cleanup after processing

🔧 Implementation:
- Create watching_list.go for PR tracking
- Refactor checker.go to use watching list
- Auto-add PRs to watching list on creation
- Remove github_owner/repo requirement
- Add comprehensive watch commands (install/status/log/history)

📦 New Files:
- internal/watcher/watching_list.go
- internal/watcher/daemon.go
- internal/watcher/scheduler.go
- internal/watcher/checker.go
- internal/watcher/processor.go
- internal/watcher/state.go
- internal/watcher/logger.go
- internal/watcher/notifier.go
- internal/watcher/launchd.go
- cmd/qkflow/commands/watch.go

🎯 Usage:
  qkflow pr create PROJ-123    # Auto-added to watching list
  qkflow watch install         # Start daemon with auto-start
  qkflow watch status          # Check daemon status
  qkflow watch history         # View processed PRs

+### Watch Daemon (Auto-update Jira)
+
+**NEW!** Automatically monitor your PRs and update Jira when they're merged.
+
+```bash
+# Install and start watch daemon (with auto-start on login)
+qkflow watch install
+
+# Check daemon status
+qkflow watch status
+
+# View processing history
+qkflow watch history
+
+# View logs
+qkflow watch log
+qkflow watch log --follow
+
+# Manual check (without daemon)
+qkflow watch check
+
+# Stop/Start daemon
+qkflow watch stop
+qkflow watch start
+
+# Uninstall daemon
+qkflow watch uninstall
+```
+
+**What it does:**
+- ✅ Monitors YOUR PRs every 15 minutes (8:30-24:00)
+- ✅ Night mode: checks at 2:00 and 6:00 only
+- ✅ Auto-updates Jira status when PR is merged
+- ✅ Desktop notifications (macOS)
+- ✅ Auto-start on login (launchd on macOS)
+- ✅ Logs all activities
+- ✅ No manual intervention needed!
+
+**Prerequisites:**
+1. Run `qkflow jira setup` first to configure Jira status mappings
+2. Make sure "PR Merged" status is configured (default: "In Review")
+
+📖 See [Jira Status Config Guide](JIRA_STATUS_CONFIG.md) for setup details.
