Commit initial framework for SDK test harness integration

[eli-r-ph]

💡 Motivation and Context

Integrate the SDK test harness library into posthog-rs, including SDK wrapper for capture V0 and V1 test suite, Docker-based test harness, Actions etc.

The "legacy" capture suite should run as expected, with compliant functionality passing. The v1 suite will fail at first: I'm stubbing a 5xx-only endpoint and will implement the new v1 capture submission functionality in a follow on PR.

The new test harness integration will land initially without being required in CI; we can enable that in a follow on once it's smoke-tested as well

💚 How did you test it?

Locally and in CI

[jose-sequeira]

Should use the harness in parallel mode, so that harness tests run faster.

   Mutex held across async network I/O blocks claimed parallel support

   The instances lock is acquired at the top of capture_event and is never released before client.capture(event).await resolves. Since all test-ids share the same Arc<Mutex<...>>, every concurrent /capture call queues behind this single lock, serializing all traffic regardless of test_id. This directly contradicts SUPPORTS_PARALLEL: bool = true and the --concurrency 10 setting in docker-compose — the test harness will see throughput capped at 1 in-flight capture at a time, which may cause timeout failures in the parallel test suite.

   The fix is to clone (or Arc-wrap) the Client out of the locked section, drop the lock, and then perform the network call and state update in a second short-lived lock acquisition.

   **Mutex held across async network I/O blocks claimed parallel support**
   
   The `instances` lock is acquired at the top of `capture_event` and is never released before `client.capture(event).await` resolves. Since all test-ids share the same `Arc<Mutex<...>>`, every concurrent `/capture` call queues behind this single lock, serializing all traffic regardless of `test_id`. This directly contradicts `SUPPORTS_PARALLEL: bool = true` and the `--concurrency 10` setting in docker-compose — the test harness will see throughput capped at 1 in-flight capture at a time, which may cause timeout failures in the parallel test suite.
   
   The fix is to clone (or `Arc`-wrap) the `Client` out of the locked section, drop the lock, and then perform the network call and state update in a second short-lived lock acquisition.
   
   How can I resolve this? If you propose a fix, please make it concise.

   pending_events is always 0; increment/decrement happen in the same branch

   In the Ok arm, pending_events is incremented to 1 and then immediately decremented back to 0 in consecutive lines — both execute only after client.capture(event).await has already returned. The field will always read 0 in /state responses. To track genuinely in-flight events, the increment must happen before the lock is released (i.e., before the await), and the decrement after the await in a re-acquired lock — which is the same restructuring needed for the parallelism fix above.
