调研方向

Start at DockerImage.parse in lean/models/docker.py and reproduce the two failing cases from the issue. The rule is to treat only a final colon segment without / as the tag; add cases covering registry ports and tags to the existing DockerImage parse tests (look under tests/) so both parse and error paths are covered. Note that linked PR #670 is already open against this issue, so confirm with maintainers before starting.

描述

Expected Behavior

An image hosted on a registry that listens on a port, for example localhost:5000/lean or registry.example.com:5000/quantconnect/lean:123, can be used with --image and with lean config set engine-image / research-image.

Actual Behavior

DockerImage.parse splits on every colon, so the registry port is read as the tag:

localhost:5000/lean          -> DockerImage(name='localhost', tag='5000/lean')
localhost:5000/lean:latest   -> ValueError: too many values to unpack (expected 2)
Potential Solution

Only treat what follows the last colon as the tag, and only when it does not contain a /. I can open a PR with the fix and tests.

Reproducing the Problem
from lean.models.docker import DockerImage
DockerImage.parse("localhost:5000/lean")
DockerImage.parse("localhost:5000/lean:latest")
System Information

lean-cli master at 20e58aa, Python 3.13, Linux.
