feat(gtm-manager): Rename to ourdigital-gtm-manager and add dataLayer injector

BREAKING CHANGE: Renamed from 13-gtm-audit to 13-ourdigital-gtm-manager

New Features:
- DataLayerInjector class for generating custom HTML tags
- Support for 20+ GA4 event types (ecommerce, forms, video, engagement)
- Subcommand structure: audit and inject modes
- Preset tag generation (ecommerce, engagement, all)
- DOM scraping option for dynamic value extraction
- Generate tags from audit report findings
- Korean payment method support (카카오페이, 네이버페이, 토스)

CLI Changes:
- `python gtm_manager.py audit --url ...` for auditing
- `python gtm_manager.py inject --preset ecommerce` for tag generation
- `python gtm_manager.py inject --event purchase --event add_to_cart`
- `python gtm_manager.py inject --from-audit report.json`

-# GTM Audit Tool
-
-Automated Google Tag Manager audit toolkit using Playwright browser automation.
-
-## Project Overview
-
-This tool audits GTM container installations, validates dataLayer events, tests form tracking, simulates e-commerce checkout flows, and generates comprehensive reports.
-
-## Quick Commands
-
-```bash
-# Install dependencies
-pip install playwright
-playwright install chromium
-
-# Run full audit
-python gtm_audit.py --url "https://example.com" --journey full
-
-# Form tracking audit
-python gtm_audit.py --url "https://example.com/contact" --journey form
-
-# E-commerce checkout flow
-python gtm_audit.py --url "https://example.com/cart" --journey checkout
-
-# DataLayer deep inspection
-python gtm_audit.py --url "https://example.com" --journey datalayer
-
-# With specific container validation
-python gtm_audit.py --url "https://example.com" --container "GTM-XXXXXX"
-```
-
-## Journey Types
-
-| Journey | Description |
-|---------|-------------|
-| `pageview` | Basic page load + scroll simulation |
-| `scroll` | Scroll depth trigger testing (25%, 50%, 75%, 90%) |
-| `form` | Form discovery, field analysis, interaction simulation |
-| `checkout` | E-commerce flow: cart → checkout → shipping → payment → purchase |
-| `datalayer` | Deep dataLayer validation and event sequence analysis |
-| `full` | All of the above combined |
-
-## Output
-
-Generates `gtm_audit_report.json` with:
-- Container status (installed, position, duplicates)
-- DataLayer analysis (events, validation issues, sequence errors)
-- Form analysis (forms found, tracking readiness, missing events)
-- Checkout analysis (elements detected, flow issues)
-- Network requests (GA4, Meta, LinkedIn, etc.)
-- Recommendations and checklist
-
-## Notion Integration
-
-Export audit results directly to Notion database for tracking and collaboration.
-
-```bash
-# Export to default Notion database (OurDigital GTM Audit Log)
-python gtm_audit.py --url "https://example.com" --notion
-
-# Export with detailed content (issues, recommendations, checklist)
-python gtm_audit.py --url "https://example.com" --notion --notion-detailed
-
-# Export to custom Notion database
-python gtm_audit.py --url "https://example.com" --notion --notion-database "your-database-id"
-```
-
-### Notion Database Schema
-
-| Property | Type | Description |
-|----------|------|-------------|
-| Site | Title | Domain name of audited site |
-| Audit ID | Text | Unique identifier (GTM-domain-date-hash) |
-| URL | URL | Full audited URL |
-| Audit Date | Date | When audit was performed |
-| Journey Type | Select | Audit journey type |
-| GTM Status | Select | Installed / Not Found / Multiple Containers |

-| Summary | Text | Quick summary of findings |
-
-### Environment Variables
-
-Set `NOTION_TOKEN` or `NOTION_API_KEY` for Notion API authentication:
-
-```bash
-export NOTION_TOKEN="secret_xxxxx"
-```
-
-### Default Database
-
-Default Notion database: [OurDigital GTM Audit Log](https://www.notion.so/2cf581e58a1e8163997fccb387156a20)
-
-## Key Files
-
-- `gtm_audit.py` - Main audit script
-- `docs/ga4_events.md` - GA4 event specifications
-- `docs/ecommerce_schema.md` - E-commerce dataLayer structures
-- `docs/form_tracking.md` - Form event patterns
-- `docs/checkout_flow.md` - Checkout funnel sequence
-- `docs/datalayer_validation.md` - Validation rules
-- `docs/common_issues.md` - Frequent problems and fixes
-
-## Coding Guidelines
-
-When modifying this tool:
-
-1. **Tag Destinations**: Add new platforms to `TAG_DESTINATIONS` dict
-2. **Event Validation**: Add requirements to `GA4_EVENT_REQUIREMENTS` dict
-3. **Form Selectors**: Extend `FormAnalyzer.discover_forms()` for custom forms
-4. **Checkout Elements**: Add selectors to `CheckoutFlowAnalyzer.detect_checkout_elements()`
-
-## Korean Market Considerations
-
-- Support Korean payment methods (카카오페이, 네이버페이, 토스)
-- Handle KRW currency (no decimals)
-- Include Kakao Pixel and Naver Analytics patterns
-- Korean button text patterns (장바구니, 결제하기, 주문하기)
-
-## Testing a New Site
-
-1. Run with `--journey full` first to get complete picture
-2. Check `gtm_audit_report.json` for issues
-3. Focus on specific areas with targeted journey types
-4. Use `--container GTM-XXXXXX` to validate specific container
-
-## Common Tasks
-
-### Add support for new tag platform
-```python
-# In TAG_DESTINATIONS dict
-"NewPlatform": [
-    r"tracking\.newplatform\.com",
-    r"pixel\.newplatform\.com",
-],
-```
-
-### Add custom form field detection
-```python
-# In FormAnalyzer.discover_forms()
-# Add new field types or selectors
-```
-
-### Extend checkout flow for specific platform
-```python
-# In CheckoutFlowAnalyzer.detect_checkout_elements()
-# Add platform-specific selectors
-```

+playwright install chromium
+
+# AUDIT MODE
+# Run full audit
+python gtm_manager.py audit --url "https://example.com" --journey full
+
+# Audit with Notion export
+python gtm_manager.py audit --url "https://example.com" --notion
+
+# Audit and generate missing tags
+python gtm_manager.py audit --url "https://example.com" --generate-tags
+
+# INJECT MODE
+# List available event types
+python gtm_manager.py inject --list-events
+
+# Generate all ecommerce tags
+python gtm_manager.py inject --preset ecommerce --output ./tags
+
+# Generate specific event tags
+python gtm_manager.py inject --event purchase --event add_to_cart
+
+# Generate from audit report
