Performance updates

[dermatz]

This pull request introduces several optimizations and new features to the magento-log-viewer extension, focusing on performance improvements, better user experience, and enhanced functionality for handling log and report files. Key changes include caching mechanisms, improved file handling, and updates to badge counts and log entry processing.

Performance Improvements:

• Pre-compilation of regular expressions for timestamps: Prevents repeated compilation on each call, improving efficiency. (src/helpers.ts)
• Caching for JSON reports: Avoids redundant reading and parsing of JSON files by implementing a caching mechanism. (src/helpers.ts)
• Optimized line counting with caching: Reduces time spent counting lines in large files and avoids repeated calculations for unchanged files. (src/helpers.ts)

Enhanced User Experience:

• Improved badge updates with throttling and debouncing: Prevents frequent updates and implements efficient counting methods for log entries and report files. (src/helpers.ts) [1] [2]
• Dialog for selecting log files when no path is provided: Adds a user-friendly selection dialog for navigating to log files or specific lines when the file path is missing. (src/helpers.ts)

Functional Enhancements:

• New commands added: Introduced magento-log-viewer.openFile and magento-log-viewer.openFileAtLine commands to improve file navigation capabilities. (package.json)
• Improved log entry counting: Counts actual log entries instead of lines, ensuring accurate representation of log data. (src/logViewer.ts) [1] [2]
