[Code Quality] Add package-level documentation for major packages

[github-actions]

Description

Major packages lack package-level documentation comments, which affects pkg.go.dev presentation and developer onboarding. Go convention requires // Package X comments for proper API documentation.

Missing Package Docs

The following packages have no package-level documentation:

• pkg/workflow/ - 600+ files, core compilation functionality
• pkg/types/ - Type definitions
• pkg/cli/ - CLI interface
• pkg/parser/ - Markdown/YAML parsing
• pkg/logger/ - Logging utilities

Proposed Solution

Add comprehensive package documentation following this template:

// Package workflow provides compilation and generation of GitHub Actions workflows
// from markdown-based agentic workflow specifications.
//
// The workflow package is the core of gh-aw, handling the transformation of
// user-friendly markdown files into production-ready GitHub Actions YAML workflows.
// It supports advanced features including:
//   - Agentic AI workflow execution with Claude, Codex, and Copilot engines
//   - Safe output handling with configurable permissions
//   - MCP (Model Context Protocol) server integration
//   - Network sandboxing and firewall configuration
//   - Dynamic tool registration and custom action generation
//
// # Basic Usage
//
// To compile a workflow from markdown:
//
//     compiler := workflow.NewCompiler(workflow.CompilerOptions{
//         Verbose: true,
//         Version: "1.0.0",
//     })
//     err := compiler.CompileWorkflow("path/to/workflow.md")
//
// # Architecture
//
// The compilation process consists of several stages:
//  1. Frontmatter parsing (extracting YAML metadata)
//  2. Markdown processing (prompt extraction)
//  3. Tool configuration (MCP servers, safe outputs)
//  4. Job generation (main, activation, safe output jobs)
//  5. YAML generation (final GitHub Actions workflow)
//
// For more details, see the Compiler type documentation.

Files to Create/Update

• pkg/workflow/doc.go (new file)
• pkg/types/doc.go (new file)
• pkg/cli/doc.go (new file)
• pkg/parser/doc.go (new file)
• pkg/logger/doc.go (new file)

Success Criteria

• Package documentation added for all 5 major packages
• Documentation includes:
  • Package purpose and responsibility
  • Key features and capabilities
  • Basic usage examples
  • Architecture overview (where applicable)
• Verify with go doc pkg/workflow
• Check pkg.go.dev rendering
• Ensure examples compile
• Review for accuracy

Impact

• Severity: Medium-High - Affects API discoverability and onboarding
• Effort: Medium - Estimated 2-3 hours total
• Risk: Low - Documentation-only change
• Benefit: Improved developer experience, better pkg.go.dev presentation
