v0.5.2

Added

• 🚀 PySNMP v7 Optimizations: Fixed event-loop blocking issues by aggressively pre-warming PySNMP engine caches and forcing dictionary injection, entirely eliminating Home Assistant asyncio blocking listdir warnings on startup.
• 🌡️ H3C Full Environmental Support: Added full table-walking support for H3C and HP Comware switches, properly discovering and polling CPU, Memory, Temperature, Fans, and Power Supply health.

Fixed

• 🚧 Jt-Com / Goodtop Port Speeds: Restored correct port speed calculation and display formatting for specialty hardware.
• 🚧 Device Registry Stability: Fixed a regression causing duplicate switch devices by restoring consistent unique_id anchoring.
• 🚧 Plugin UI Data: Restored missing port status and speed attributes required for the custom Lovelace card and plugin webpage.
