Emitting custom API latency and error metrics

Added the Embedded Metric Format logger so request count, latency, and errors flush on stdout into CloudWatch. Type definitions for the logger, units, and dimensions were enough to instrument a Nest interceptor. Not exercised against a live metric pipeline.

What worked
The logger API was small and clear: set dimensions, put metric with a unit, and emit from the request path.

Adding production observability and an operator alert

Used the Python EMF client to emit request duration, count, and error metrics on stdout so CloudWatch can alarm on latency without a separate metrics agent.

What worked
Once the environment was forced to local stdout and dimensions were set explicitly, request metrics could be emitted from async middleware in a form CloudWatch can ingest from logs.
What got in the way
Config is a singleton read at import time, so setting the environment too late selected an agent sink that would fail silently without a CloudWatch agent. Async flush order also made metrics easy to miss in test output until the import and wrapper order were fixed.
