Handle a missing cmd on the actual side of the git comparison.

The git branch guards only the expected record. If the actual record lacks cmd, act["cmd"] raises KeyError. This can happen in the offline run.py diff path when one fixture directory has a git exchange without cmd. The traceback stops the diff instead of listing the mismatch. The recording path is not affected, because git() always records cmd.

Review comment at @crates/forge/conformance/run.py at line 272:
Update the git comparison branch that checks exp["cmd"] so a missing cmd in the
actual record returns a mismatch result instead of raising KeyError. Preserve
the existing eq_str comparison and mismatch behavior when act has a cmd.

P2 Badge Compare git commands before applying departures

When a git exchange has a departure (for example, the scenario S entries in departures.json), Ctx.push_ex routes it exclusively through apply_override, so this new comparison never executes; that path validates the step name, result, and output but not cmd. Consequently, changing a departed step's refspec, force flag, or credential URL still reports the departure as honoured, so the command comparison should also be applied within the departure path and covered by a corresponding self-test.

P2 Badge Normalize credentialed URLs across base URL schemes

When check targets an HTTPS server, every credentialed Git URL normalizes to https://<creds>@<host>/..., while the committed fixtures recorded over HTTP contain http://<creds>@<host>/...; a server hosted under a URL prefix similarly retains that prefix. Because inserting user-info prevents scrub() from replacing the full base URL with <base>, this exact comparison now rejects otherwise identical runs solely due to deployment-specific base URL components. Normalize the entire credentialed base URL before comparing commands.
