[log] Add debug logging to CLI and workflow packages

[github-actions]

Summary

Enhanced 5 Go files with debug logging statements to improve troubleshooting and development workflow. All enhancements follow the project's logging guidelines from AGENTS.md.

Files Enhanced

CLI Package (4 files)

1. pkg/cli/mcp_registry.go (409 lines)

   • MCP registry client creation with URL logging
   • Server search operations with query parameters
   • Server processing count from registry responses
   • Filtered server count after local query matching
   • Server fetch operations with server name
   • Server found/not found status logging

2. pkg/cli/remove_command.go (397 lines)

   • Workflow removal entry with pattern and keepOrphans flag
   • Workflow file count discovered during scanning
   • Workflows matched count for removal
   • Orphaned includes cleanup initiation
   • No markdown files found during cleanup

3. pkg/cli/spec.go (389 lines)

   • Repository spec parsing entry
   • Workflow spec parsing with format detection
   • GitHub URL format detection
   • Local path format detection
   • Source spec parsing entry
   • Parsed source spec details (repo, path, ref)

4. pkg/cli/enable.go (370 lines)

   • Workflow toggle operations with action, count, and repo
   • All workflows processing when no specific names provided
   • Disable all workflows except specific ones
   • YAML workflow file count discovered

Workflow Package (1 file)

5. pkg/workflow/expression_nodes.go (205 lines)
   • Multiline disjunction rendering with term count

Logging Guidelines Followed

✅ Logger declaration: Each file uses the pkg:filename naming convention
✅ Function entry logging: Added logs at entry points with relevant parameters
✅ Control flow logging: Added logs for important branching decisions
✅ State change logging: Added logs before/after significant operations
✅ No side effects: All logger arguments use existing variables without computation
✅ No test files modified: Skipped all *_test.go files

Validation

• ✅ Build passes: make build completes successfully
• ✅ Debug logging works: Tested with DEBUG=* ./gh-aw compile dev
• ✅ All 5 files compile without errors
• ✅ No breaking changes to existing functionality

Example Debug Output

When running with DEBUG=*, users will now see detailed logging for:

• MCP registry operations and server lookups
• Workflow removal and cleanup operations
• Spec parsing and format detection
• Workflow enable/disable operations
• Expression node rendering

This will significantly improve troubleshooting capabilities for developers working on these components.
