between the time we check for `is_open` and the actual disconnect, the
socket could already have been disconnected by another thread (TOCTOU).
Furthermore, the disconnects can race causing a segfault or similar
issue in the asio's internals.
with this many http connnections, we were exhausting all available file
descriptors, leading to a dead server that keeps CLOSE_WAIT tcp sockets.
Because we want to retain the behavior that we keep connections open for
reuse, we instead make a pool of 8 curl instances now, shared between
all the different requests.
this was exhausting file descriptors with enough concurrent reads, from
what I can tell. Either way, spawning a new OS thread per read is not
the way.
Because this is so critical, I added unit-tests for that behavior.
this happens when, somehow, the client disconnects before we get here.
I had this happen when breaking in the debugger and continuing, which
leads to clients timing out (client-side timeouts).

This PR adds a boolean parameter to the MP.SendChatMessage function that
allows logging the message or not (default true).
I took an example from the ``set_function("SendNotification" ...`` to
make the default value working.
It's my first time actually doing C++, I hope it's alright!

## Summary
Reject malformed vehicle reset and paint packets before slicing
structured payloads, and catch parser exceptions in the TCP client loop.
## Problem
Or:<pid>-<vid>:null and similarly malformed Op packets could reach
substr(npos) in ParseVehicle, throwing std::out_of_range. On TCP, that
exception could escape the client loop and kill the thread.
## Changes
- Guard Or reset packets when no { payload exists
- Guard Op paint packets when no [ payload exists
- Add a small helper and unit test for structured payload extraction
- Catch std::exception around GlobalParser in the TCP client loop and
disconnect the offending client
## Verification
- git diff --check
- Full build/tests not run in this shell because cmake was not installed
add/test Debian 13 build to github actions
Closes#464

- Avoid redundant substr() calls in packet parsing hot-path
(TServer.cpp)
The previous code called substr(3) twice per packet, creating
unnecessary temporary strings. Now stores the result once.
- Replace .size() == 0 with .empty() for idiomatic C++
(TConsole.cpp, TLuaEngine.cpp)
When Acceptor.accept() returns an error (e.g., "Too many open files"),
the server was continuing to process an invalid socket, causing resource
leaks and potential infinite error loops.
Add continue statement to skip processing when accept() fails, allowing
the server to retry on the next iteration instead of crashing.
Fixes resource exhaustion DoS vulnerability where server would enter
error loop instead of handling gracefully.
