Move deprecated scripts to deprecated/ folder

Moved 3 scripts that are no longer recommended for installation:
- install-claude-customizations.sh (replaced by interactive installer)
- export-claude-customizations.sh (export utility, not needed for install)
- sync-agents.sh (sync utility, not needed for install)

Users should use interactive-install-claude.sh or MASTER-PROMPT.md instead.

+# Deprecated Scripts
+
+This folder contains scripts that are no longer maintained or recommended for use.
+
+## Why These Scripts Are Deprecated
+
+### 1. install-claude-customizations.sh
+- **Status**: Replaced by `interactive-install-claude.sh`
+- **Reason**: The interactive installer provides better user experience with more options
+- **Alternative**: Use `./interactive-install-claude.sh` instead
+
+### 2. export-claude-customizations.sh
+- **Status**: Not needed for initial installation
+- **Reason**: This is an export utility for backing up customizations, not required for setup
+- **Alternative**: Manual backup or version control
+
+### 3. sync-agents.sh
+- **Status**: Not needed for initial installation
+- **Reason**: This syncs agents with external repos, not required for initial setup
+- **Alternative**: Git-based management or manual updates
+
+## Recommended Installation Method
+
+Use the **Interactive Installer** for all new installations:
+
+```bash
+./interactive-install-claude.sh
+```
+
+Or follow **MASTER-PROMPT.md** for manual setup.
+
+## Note
+
+These scripts are kept for historical reference only. They may not work with current versions of Claude Code and are not supported.
