[log] Add debug logging to CLI and workflow processing modules

[github-actions]

Summary

Enhanced 5 Go files in the CLI package with comprehensive debug logging to improve troubleshooting and development visibility. Added logger declarations and meaningful logging calls following the project's logging guidelines from AGENTS.md.

Files Modified

1. pkg/cli/mcp_inspect_inspector.go (213 lines)

   • Added logger declaration: mcpInspectorLog
   • Logs MCP server extraction, stdio server startup, process management, and inspector lifecycle
   • Tracks server PIDs, configuration counts, and cleanup operations

2. pkg/cli/add_workflow_compilation.go (134 lines)

   • Added logger declaration: addWorkflowCompilationLog
   • Logs workflow compilation operations with file tracking
   • Records refresh settings, lock file status, and compilation results

3. pkg/cli/add_workflow_pr.go (115 lines)

   • Added logger declaration: addWorkflowPRLog
   • Tracks PR creation workflow from branch creation through push
   • Logs workflow additions, file staging, and PR creation success/failure

4. pkg/cli/update_merge.go (208 lines)

   • Added logger declaration: updateMergeLog
   • Logs 3-way merge operations and local modification detection
   • Records merge conflicts, exit codes, and source spec parsing

5. pkg/cli/mcp_tool_table.go (224 lines)

   • Added logger declaration: mcpToolTableLog
   • Logs MCP tool table rendering and hierarchy tree generation
   • Tracks tool counts, permission settings, and wildcard detection

Logging Guidelines Followed

• Logger naming follows pkg:filename convention (e.g., cli:mcp_inspect_inspector)
• Log messages are meaningful and provide debugging context
• No side effects in logger arguments (values logged directly, no function calls)
• Logs function entry with key parameters
• Logs important control flow decisions and state changes
• Logs errors with context before returning
• Used appropriate log levels (Printf for structured data, Print for simple messages)

Validation

• ✅ Build successful: make build completed without errors
• ✅ Code compiles cleanly with no syntax errors
• ✅ Logger imports added correctly
• ✅ All logging calls follow project guidelines

Benefits

• Improved visibility into MCP server lifecycle and tool inspection
• Better debugging for workflow compilation and PR creation flows
• Enhanced troubleshooting for merge operations and conflict resolution
• Easier diagnosis of tool table rendering issues
• All logging respects the DEBUG environment variable for opt-in visibility
