The bug manifests as orphan getaddrinfo_a resolver workers that keep the
runner from completing job teardown -- the previous run had all steps
succeed in ~1m37s but then hung in "Cleaning up orphan processes" for
~57m before GitHub force-killed the job.
A job-level timeout-minutes makes the failure signal fast and predictable:
bug present -> killed at 5 min, bug fixed -> ~2 min pass. Step-level timeout
isn't enough since the hang is in post-job cleanup, not the test step.
On Linux/glibc, getaddrinfo_with_timeout() runs DNS asynchronously via
getaddrinfo_a(GAI_NOWAIT) using a stack-local gaicb. When gai_suspend()
hits the connection timeout, gai_cancel() is called and the function
returns immediately — but gai_cancel() is non-blocking and can return
EAI_NOTCANCELED, leaving the resolver worker thread alive and still
referencing the destroyed stack frame.
Adds three opt-in gtest cases (GetAddrInfoAsyncCancelTest.*) that
exercise the cancel path repeatedly. They are gated on Linux/glibc +
CPPHTTPLIB_USE_NON_BLOCKING_GETADDRINFO at compile time, and on the
CPPHTTPLIB_TEST_ISSUE_2431=1 env var at runtime, so a normal `make
test` run is unaffected.
Also adds a dedicated CI job (issue-2431-repro) and a Docker-based
local runner (test/run_issue_2431_repro.sh) that sinkhole UDP/53 so
the timeout branch is taken, and run the test under ASAN/LSAN. With
the bug present these runs are expected to fail; with a fix applied
they should pass.

* WebSocket support
* Validate selected subprotocol in WebSocket handshake
* Fix problem with a Unit test
* Dynamic Thread Pool support
* Fix race condition in new Dynamic ThreadPool
* Fix problem with 'windows without SSL`
* Fix payload limit enforcement for requests without Content-Length on Windows
- Enable MSG_PEEK on Windows (non-SSL builds) to detect payloads without Content-Length
- Only use MSG_PEEK when payload_max_length is set to a finite value to avoid blocking
- Use read_content_without_length for actual size checking to support any payload limit
- Set 413 Payload Too Large status before rejecting oversized requests
This fixes three test cases on Windows:
- RequestWithoutContentLengthOrTransferEncoding (no payload limit)
- NoContentLengthPayloadLimit (8-byte limit)
- NoContentLengthExceeds10MB (10MB limit)

* Wrap poll()/WSAPoll() in a function
Instead of using a macro for poll() on Windows, which breaks when the
implementation is compiled separately, add a detail::poll_wrapper()
function that dispatches to either ::poll() or ::WSAPoll().

This CI workflow checks ABI compatibility between the pushed commit and
the latest tagged release, helping preventing accidental ABI breaks.

This integrates the "main" test suite (test/test.cc) in Meson.
This allows to run the tests in the CI with the Meson-built version of
the library to ensure that nothing breaks unexpectedly.
It also simplifies life of downstream packagers, that do not have to
write a custom build script to split the library and run tests but can
instead just let Meson do that for them.
