Implement TED Scraper and Configuration Management

- Introduced a new TED scraper in `cmd/scraper` to handle downloading and parsing TED XML files. - Added configuration management for the scraper, including a new `Config` struct and YAML configuration file. - Created necessary handler, service, and repository layers for tender management, adhering to Clean Architecture principles. - Implemented comprehensive logging and error handling throughout the scraper functionality. - Updated API routes to include tender management operations, enhancing the overall system capabilities.

+## 🔧 Usage Examples
+
+### Basic Document Parsing
+
+```go
+package main
+
+import (
+    "fmt"
+    "io/ioutil"
+    "log"
+    
+    "tm/ted"
+)
+
+func main() {
+    // Create comprehensive TED parser
+    parser := ted.NewTEDParser()
+    
+    // Read any TED XML file
+    xmlData, err := ioutil.ReadFile("ted_document.xml")
+    if err != nil {
+        log.Fatal(err)
+    }
+
+    // Automatic detection and parsing
+    parsedDoc, err := parser.ParseXML(xmlData)
+    if err != nil {
+        log.Fatal(err)
+    }
+
+    // Get document information
+    document := parsedDoc.GetDocument()
+    fmt.Printf("Document Type: %s\n", parsedDoc.Type)
+    fmt.Printf("Document ID: %s\n", document.GetID())
+    fmt.Printf("Notice Type: %s\n", document.GetNoticeType())
+    fmt.Printf("Language: %s\n", document.GetLanguage())
+    
+    // Validate document
+    if err := document.Validate(); err != nil {
+        log.Printf("Validation error: %v", err)
+    }
+}
+```
+
+### Advanced Usage by Document Type
+
+```go
+// Handle specific document types
+switch parsedDoc.Type {
+case ted.DocumentTypeContractNotice:
+    cn := parsedDoc.ContractNotice
+    fmt.Printf("Tender Deadline: %s\n", cn.GetTenderDeadline())
+    amount, currency := cn.GetBudget()
+    fmt.Printf("Estimated Value: %s %s\n", amount, currency)
+    
+case ted.DocumentTypeContractAwardNotice:
+    can := parsedDoc.ContractAwardNotice
+    fmt.Printf("Award Date: %s\n", can.GetAwardDate())
+    amount, currency := can.GetTotalAwardValue()
+    fmt.Printf("Total Award: %s %s\n", amount, currency)
+    
+case ted.DocumentTypePriorInformationNotice:
+    pin := parsedDoc.PriorInformationNotice
+    fmt.Printf("Prior Information ID: %s\n", pin.GetID())
+    
+case ted.DocumentTypeDesignContest:
+    dc := parsedDoc.DesignContest
+    fmt.Printf("Design Contest ID: %s\n", dc.GetID())
+    if dc.ContestDesignJury != nil {
+        fmt.Printf("Jury Decision: %s\n", dc.ContestDesignJury.JuryDecision)
+    }
+    
+case ted.DocumentTypeQualificationSystemNotice:
+    qsn := parsedDoc.QualificationSystemNotice
+    fmt.Printf("Qualification System ID: %s\n", qsn.GetID())
+    
+case ted.DocumentTypeConcessionNotice:
+    cn := parsedDoc.ConcessionNotice
+    fmt.Printf("Concession ID: %s\n", cn.GetID())
+    if cn.ConcessionRevenue != nil {
+        fmt.Printf("Revenue Type: %s\n", cn.ConcessionRevenue.RevenueType)
+    }
+    
+case ted.DocumentTypePlanningNotice:
+    pn := parsedDoc.PlanningNotice
+    fmt.Printf("Planning ID: %s\n", pn.GetID())
+    fmt.Printf("Budget Lines: %d\n", len(pn.BudgetAccountLine))
+    
+case ted.DocumentTypeResultNotice:
+    rn := parsedDoc.ResultNotice
+    fmt.Printf("Result ID: %s\n", rn.GetID())
+    fmt.Printf("Tender Results: %d\n", len(rn.TenderResult))
+    
+case ted.DocumentTypeChangeNotice:
+    cn := parsedDoc.ChangeNotice
+    fmt.Printf("Change ID: %s\n", cn.GetID())
+    fmt.Printf("Change Reasons: %d\n", len(cn.ChangeReason))
+    
+case ted.DocumentTypeSubcontractNotice:
+    sn := parsedDoc.SubcontractNotice
+    fmt.Printf("Subcontract ID: %s\n", sn.GetID())
+    fmt.Printf("Subcontract Calls: %d\n", len(sn.SubcontractCall))
+}
+```
+
+### Working with Organizations and Extensions
+
+```go
+// Extract organization information (works for all notice types)
+if doc := parsedDoc.GetDocument(); doc != nil {
+    // Type assertion for specific methods
+    if notice, ok := doc.(*ted.ContractNotice); ok {
+        orgs := notice.GetOrganizations()
+        if orgs != nil {
+            fmt.Printf("Organizations: %d\n", len(orgs.Organization))
+            for _, org := range orgs.Organization {
+                if org.Company != nil && org.Company.PartyName != nil {
+                    fmt.Printf("- %s\n", org.Company.PartyName.Name)
+                }
+            }
+        }
+        
+        // Get publication information
+        pub := notice.GetPublicationInfo()
+        if pub != nil {
+            fmt.Printf("Publication ID: %s\n", pub.NoticePublicationID)
+            fmt.Printf("OJS ID: %s\n", pub.GazetteID)
+            fmt.Printf("Publication Date: %s\n", pub.PublicationDate)
+        }
+    }
+}
+```
+
+## 🔍 Document Type Detection
+
+The parser includes intelligent document type detection:
+
+```go
+// Detect document type without parsing
+docType, err := parser.DetectDocumentType(xmlData)
+if err != nil {
+    log.Fatal(err)
+}
+
+fmt.Printf("Detected document type: %s\n", docType)
+
+// Parse specific type if known
+switch docType {
+case ted.DocumentTypeContractNotice:
+    notice, err := parser.ParseXMLAsContractNotice(xmlData)
+case ted.DocumentTypePriorInformationNotice:
+    notice, err := parser.ParseXMLAsPriorInformationNotice(xmlData)
+case ted.DocumentTypeDesignContest:
+    notice, err := parser.ParseXMLAsDesignContest(xmlData)
+// ... other specific parsers available
+}
+```
+
+## ✅ Comprehensive Validation
+
+All notice types include thorough validation:
+
+```go
+// Validate any notice type
+err := notice.Validate()
+if err != nil {
+    log.Printf("Validation failed: %v", err)
+}
+```
+

+- **Concurrent Safe**: Thread-safe parser instances
+- **Error Resilient**: Graceful handling of malformed or incomplete XML
+
+## 🔗 Dependencies
+
+- Go 1.19+
+- Standard library: `encoding/xml`, `time`, `fmt`
+- Custom XML parser: `tm/pkg/xmlparser`
+
+## 📈 Future Extensions
+
+This model is designed to be forward-compatible with:
+- New eForms SDK versions
+- Additional notice subtypes
+- Extended business groups
+- Enhanced validation rules
+- Performance optimizations
+
+The comprehensive nature of this TED XML model ensures complete coverage of all procurement notice types and supports the full lifecycle of European public procurement processes.
