Add healthcheck and switch to gost

[BaziForYou]

• Maintained curl for healthchecks: Kept curl in the Dockerfile to ensure the container accurately verifies Cloudflare WARP routing status.
• Swapped socat for gost (latest v3): Replaced socat with the latest GOST v3 to multiplex port 40000. This delivers better performance and acts as a universal translator, seamlessly auto-detecting and routing HTTP, HTTPS (CONNECT), SOCKS4, and SOCKS5 proxy traffic on a single exposed port.

• Memory Optimization: Sets GOMEMLIMIT and GOGC to heavily restrict the gost multiplexer's memory footprint. This drops active memory consumption from 200 - 500 MB to 100 - 200 MB.
• Log Silencing: Hides normal warp-cli command outputs and filters out persistent, non-fatal DBus errors from warp-svc. Sets gost to only log warnings.
• Signal Handling: Traps SIGTERM and SIGINT to gracefully kill warp-svc when the Docker container stops, rather than relying on a hard exec termination.
