feat: Update to latest CS2/CSS API and .NET 8.0

- Update TargetFramework from net7.0 to net8.0
- Update CounterStrikeSharp.API from 1.0.126 to 1.0.363
- Update MinimumApiVersion from 126 to 363
- Bump ModuleVersion to 0.0.6
- FIX: Replace deprecated EyeAngles with V_angle (fixes #5)
- FIX: Fix closure capture bug in timer callbacks (race condition)
- Add null checks for player pawn data
- Add xUnit test project with core logic tests
- Update solution file to include test project
- Update README with development instructions and changelog

Workflow update will be handled separately due to GitHub token scope requirements.

This update ensures compatibility with the latest Counter-Strike 2
and CounterStrikeSharp API versions.
