🔧 Hotfix v1.3.2: Fix global npm installation error 127

Critical bug fix for npm error 127 when installing globally.

- Fixed postinstall script that was causing "husky: command not found" error
- Made husky installation conditional (only runs in development environments)
- Added graceful fallback for global installs, production, and CI environments
- Postinstall script now detects installation context and skips husky when appropriate

This resolves the breaking issue that prevented users from installing
the package globally with npm install -g @clduab11/gemini-flow.

+# Scripts Directory
+
+## postinstall.cjs
+
+**Purpose**: Conditional Husky installation script
+
+**Problem Solved**: Fixes npm error 127 that occurs during global installs when husky (a devDependency) is not available.
+
+**How it works**:
+- Detects production, global, or CI environments
+- Only runs `husky install` in development environments where devDependencies are available
+- Gracefully skips husky setup when not in development
+
+**Environment Detection**:
+- `NODE_ENV === 'production'`
+- `npm_config_global === 'true'` (global installs)
+- `CI` or `CONTINUOUS_INTEGRATION` environment variables
+- Missing `node_modules/husky` directory
+
+**Usage**:
+- Automatically runs via `npm install` (postinstall hook)
+- Can be run manually: `node scripts/postinstall.cjs`
+
+This ensures the package can be installed globally (`npm install -g`) or in production environments without husky-related errors while still setting up git hooks in development environments.
