Gate checkout-only CLI tests with source_checkout_root

[diegoferigo-rai]

Description

Some CLI unit tests still assume that they run from an Isaac Lab source checkout. They read the root pyproject.toml, copy the repository launcher, or execute scripts that are not shipped in the installed package. This makes the tests fail when the suite is run against an installed wheel or conda package.

Use the existing source_checkout_root fixture for these remaining tests, following the pattern introduced in #7389. The launcher and teleoperation tests also resolve checkout-only files from the path returned by the fixture.

The change consistently gates checkout-dependent CLI tests with the existing source_checkout_root fixture, allowing installed-package test runs to skip tests that require repository-only files.

• Design and architecture: Centralizing checkout detection in the existing fixture matches the established test architecture. Class-level usefixtures markers gate groups whose implementation paths may read the root project metadata; this is somewhat broad but not a merge-blocking concern.
• API: No production APIs, public symbols, CLI arguments, or documented behavior change. The compatibility surface checked is limited to test access to repository launchers, root pyproject.toml data, and teleoperation scripts.
• Implementation: Launcher copies and teleoperation script paths now resolve from the fixture-provided checkout root, with the teleoperation subprocess working directory updated consistently. Tests that indirectly read root project metadata are also gated, and the test-only .skip changelog fragment follows repository policy.

No blocking issues. No inline issue met the actionable-evidence threshold; the assessment above records the review feedback.

Automated review; human maintainers own approval decisions.

Confidence Score: 5/5

The PR appears safe to merge; the new fixture usage correctly limits checkout-dependent CLI tests without changing production behavior.

Summary

This PR consistently gates the remaining source-checkout-dependent CLI tests with the existing source_checkout_root fixture.

• Launcher tests now copy platform launchers from the fixture-provided checkout root.
• Install command tests that consume root dependency metadata skip cleanly outside a checkout.
• Teleoperation help tests resolve repository-only scripts and their working directory through the fixture.
• A skip changelog fragment records that the change is test-only.
