* Add OpenTelemetry metrics support to `wash-runtime`, introducing a `FuelConsumptionMeter` that measures Wasm fuel consumed per component invocation (HTTP requests, in-memory messaging, NATS messaging) * Wire fuel metering through the host, HTTP server, and plugin layers via an `inject_meters` pattern on `HostHandler` and `HostPlugin` traits * Add `--enable-meters` global CLI flag to `wash` that enables fuel consumption tracking and configures the Wasmtime engine with `consume_fuel` <img width="1491" height="741" alt="image" src="https://github.com/user-attachments/assets/fb672c37-0222-45f0-b388-7358e48bfc8c" /> Old PR: wasmCloud/wash#289 --------- Signed-off-by: if0ne <pavel.agafonov.al@gmail.com>

Just an experiment. I’m not sure whether we support this yet. If we decide to keep it, I can improve the developer experience for plugin authors to make it easier to integrate this metric into their code.
