feat: update docs and bump parse-jtl dependency

[ASaiAnudeep]

This change updates the project's documentation (AGENTS.md and README.md) to follow industry best practices and better support both human and agent-based development. It also upgrades the parse-jtl dependency to version 1.1.0, ensuring the project uses the latest stable version of its primary parsing engine.

Summary of changes:

• AGENTS.md: Restructured to include WHAT, WHY, HOW, and a map of the project structure to assist AI agents.
• README.md: Significantly expanded to include a list of features, installation instructions, basic and advanced usage examples (including thresholds), and a guide for contributors.
• package.json & package-lock.json: Bumped parse-jtl from 1.0.4 to 1.1.0.
