This pull request introduces several updates to the FurrDB project, including new CRUD demo examples in multiple programming languages, refactoring of script handling logic, and updates to documentation and configuration. The changes enhance usability, streamline code, and improve clarity for developers.

New CRUD Demo Examples:

• Added CRUD demo implementations for FurrDB in Go (examples/crud_demo.go), Python (examples/crud_demo.py), and TypeScript/Deno (examples/crud_demo.ts). These examples demonstrate basic operations like SET, GET, DEL, and KEYS with user profile data. [1] [2] [3]

Script Handling Refactor:

• Refactored script evaluation logic in internal/script/script.go to improve modularity and readability. Introduced helper functions like handleLetStatement, handleIfStatement, and executeCommand for better separation of concerns. Removed unused args parameter from EvalScript and related methods.
• Updated corresponding tests in internal/script/script_test.go to align with the refactored script evaluation logic. [1] [2]

Codebase Improvements:

• Simplified REPL command handling in internal/repl/repl.go by replacing multiple if statements with a switch statement and removing redundant code for clearing the screen. [1] [2]
• Refactored server command processing in internal/server/server.go by introducing helper functions parseInput and processCommand for better readability and maintainability.

Documentation Updates:

• Revamped readme.md with clearer instructions for building, running, and testing the server. Added steps for using the REPL, CLI client, and release binaries. Removed outdated project structure section. [1] [2]

Configuration Enhancements:

• Enabled Deno support in .vscode/settings.json for TypeScript development.
