- Auto-refresh: before non-auth commands, if the access token is expired
but a refresh token exists, silently regenerate tokens. Prints
"Token refreshed." to stderr so users know what happened.
- FXT_PASSWORD: login reads password from this env var when set,
skipping the interactive prompt. Safer than a --password flag
(env vars don't appear in ps output or shell history).

The IB Gateway JVM uses non-blocking I/O on port 4002, which causes
EAGAIN errors with ibapi's blocking Client::connect(). The gnzsnz
image provides socat on port 4004 as a stable proxy that bridges
blocking clients to the non-blocking gateway socket.
Port 4004 is the correct client-facing port for paper mode (4003 for
live). The K8s readiness probe stays on 4002 since TCP probes work
fine with non-blocking sockets.

Add Broker variant to Commands enum with BrokerArgs (flatten),
route to execute_broker_command in match block (no JWT required),
exit(1) on check failure. Clone config.api_gateway_url to avoid
partial move. Add two CLI parsing tests for broker check.

Extend ml_training_service to dispatch GPU training jobs as K8s batch/v1
Jobs, collect results via a Rust sidecar uploader, and support model
promotion with operator approval via fxt CLI.
- K8s dispatcher creates Jobs on gpu-training pool with native sidecar
- training_uploader crate: watches DONE/FAILED marker, uploads to S3,
reports completion via ReportJobCompletion gRPC
- PromotionManager compares metrics, queues better models for approval
- 4 new proto RPCs: ReportJobCompletion, ListPendingPromotions,
ApprovePromotion, RejectPromotion
- fxt commands: train start, model list/approve/reject
- Training binaries write DONE/FAILED markers + metrics.json
- Dockerfile, K8s job template, and CI pipeline updated
- StartTraining gracefully falls back to in-process when outside K8s
- 27 new tests (16 service + 11 promotion), 141 total service tests pass
