fix: resolve relative paths correctly for monorepo support

[H3nSte1n]

🐛 Fixes

Closes #30

📝 Description

This PR fixes the issue where relative paths in the .badge-config file (like ../../README.md) were not being resolved correctly, causing "ENOENT: no such file or directory" errors in monorepo setups.

🔧 Changes Made

1. Path Resolution in Globals.ts

• Added path.resolve() to convert relative paths to absolute paths when configuration is loaded
• Ensures paths are resolved from the current working directory (process.cwd())
• Applies to both readmeFilePath and coverage_file_path configuration options

2. Fixed ReadmeWorker.ts Path Timing Issue

• Removed static filePath property that was capturing the path at class load time
• Changed to read Globals.BASE_README_PATH dynamically at runtime
• This ensures custom paths from configuration are properly used

📦 Breaking Changes

None - this is a bug fix that maintains backward compatibility.
