…nality -Key features implemented: -nHash.Application.csproj: Updated package reference from NETStandard.Library to Isopoh.Cryptography.Argon2 for proper Argon2 support -Argon2idHash.cs: Replaced custom Blake2b-based implementation with correct Argon2id algorithm using Isopoh library, including proper salt generation and verification logic -TextCounterService.cs: Modified CountCharactersWordsSentences method to return a tuple of counts instead of printing to console -FileProvider.cs: Enhanced error handling with proper exception throwing, logging support via ILogger, and improved validation for file operations -.gitignore: Updated to include common build artifacts, dependencies, logs, editor files, and OS-generated files for cleaner repository management The changes modernize the hashing implementation, improve error handling and logging, and update project dependencies for better maintainability and correctness.

Pull request overview
This PR updates infrastructure and application utilities by replacing console-based behaviors with structured return values/exceptions, introducing an Argon2id hashing implementation backed by an external library, and simplifying repository ignore rules.
Changes:
- Update
FileProviderto use an optional logger and throw exceptions on missing/invalid file paths instead of writing to console/returning empty results. - Update
TextCounterService.CountCharactersWordsSentencesto return counts as a tuple instead of printing to console. - Replace the custom Argon2id implementation with
Isopoh.Cryptography.Argon2and simplify.gitignore.
