Changes Proposed

Adds a new handler for a serverinfo message type that returns the same information as the old status protocol, in a JSON format.

How to test: after compiling, send {"type": "serverinfo"} to the HTTP server

Pull Request Overview

Adds a new HTTP serverinfo endpoint that returns server status in JSON, updates build scripts to support optional MySQL/MariaDB selection, and removes hardcoded default vcpkg features.

• Introduces handle_serverinfo handler with JSON response
• Integrates handler into the HTTP router and exposes server start time via serverStart()
• Updates CMake and vcpkg.json to drive features via CMake options instead of manifest defaults

vcpkg.json	Removed default-features block; features now driven by CMake
src/http/serverinfo.h/.cpp	Added new handler and JSON construction for /serverinfo
src/http/router.cpp	Registered serverinfo route
src/http/http.h/.cpp	Exposed serverStart() and captured start time
src/http/CMakeLists.txt	Included serverinfo sources
CMakeLists.txt	Introduced USE_LIBMYSQL option and feature-based logic

vcpkg.json:58

• Removing the default-features section can disable core features (lua, http, libmariadb) by default. Consider restoring it or mirroring those features via the manifest fields controlled by CMake options to avoid build breakage.

src/http/serverinfo.cpp:1

• The new handle_serverinfo logic isn't covered by any unit tests. Adding tests for response structure and edge cases (e.g., zero players) would ensure long-term correctness.

#include "../otpch.h"

src/http/serverinfo.h:1

• [nitpick] Public API handle_serverinfo isn't documented. Adding a brief doc comment describing expected input, response format, and status codes would improve discoverability.

#pragma once

src/http/serverinfo.cpp:22

• This use of std::format requires including <format> (or ensuring it's brought in via otpch.h). Verify you have the correct header to avoid compilation errors.

	         {{"started", std::format("{:%FT%TZ}", round<std::chrono::seconds>(serverStart()))},

src/http/serverinfo.cpp:22

• [nitpick] Consider qualifying the round call for clarity (e.g., std::chrono::round<std::chrono::seconds>(…)) to make its origin explicit.

	         {{"started", std::format("{:%FT%TZ}", round<std::chrono::seconds>(serverStart()))},

Todo: add a table when experience stages are used

It could directly return uptime, avoiding the calculation with now
