[log] Add debug logging to campaign and parser modules

[github-actions]

Summary

Enhanced 5 Go files with debug logging following project guidelines:

• pkg/campaign/status.go - Added campaign:status logger with logging for:

  • Campaign compiled state computation with workflow count
  • Workflow markdown and lock file validation
  • Lock file staleness detection
  • GitHub issue/PR counts fetching
  • Metrics and cursor tracking from repo memory

• pkg/parser/github.go - Added parser:github logger with logging for:

  • GitHub token retrieval flow
  • Environment variable detection (GITHUB_TOKEN, GH_TOKEN)
  • gh auth token command fallback

• pkg/parser/import_directive.go - Added parser:import_directive logger with logging for:

  • Import directive parsing with legacy syntax detection
  • Parsed directive details (path, optional flag, syntax type)

• pkg/parser/import_error.go - Added parser:import_error logger with logging for:

  • Import error formatting with path and location details

• pkg/parser/yaml_error.go - Added parser:yaml_error logger with logging for:

  • YAML error extraction with frontmatter offset
  • Error location extraction from goccy format
  • Fallback string parsing for error location

Changes Made

1. Added logger declarations following the pkg:filename naming convention
2. Replaced shared package-level logger usage with dedicated file-specific loggers
3. Added entry point logging for key functions
4. Added logging for important control flow decisions and state changes
5. Ensured all log arguments have no side effects

Quality Checklist

• Maximum 5 files modified
• No test files modified
• Each file has logger declaration with correct naming convention
• Logger arguments don't compute anything or cause side effects
• Logging messages are meaningful and helpful
• No duplicate logging with existing logs
• Import statements properly formatted
• Changes validated with make build (no compilation errors)
• Workflow compilation tested with ./gh-aw compile dev

Testing

Validated changes with:

make build      # ✓ Successful compilation
./gh-aw compile dev  # ✓ Successfully compiled workflow

Notes

These logging enhancements improve debugging capabilities for:

• Campaign workflow tracking and metrics
• GitHub authentication token resolution
• Import directive processing
• Error formatting and reporting
• YAML parsing error extraction

Debug logs can be enabled by setting DEBUG=* environment variable.
