Previously the tokio runtime was stashed in a hidden attribute on the reactor object, installed lazily by whichever Rust code first needed it, and started via `callWhenRunning`. Instead, we create a `RustRuntime` (accessible via `HomeServer.get_rust_runtime()`) that holds any per-reactor Rust state, such as the tokio runtime. It is constructed lazily on use. Rust consumers (`HttpClient`, `VersionsHandler`, the Python DB pool wrapper) now receive the runtime or reactor handle explicitly, and the `reactor.run()` / manual-startup workarounds in tests are no longer needed. We also add helper wrappers in Rust for `Reactor` and `HomeServer` that exposes the needed functionality. The aim is to allow us to have a Rust-side clock (mainly to get the current time), that respects the unit test per-reactor time management. --------- Co-authored-by: Claude Opus 5 (1M context) <noreply@anthropic.com>
