fix(sdk): dedupe entry-point compliance frameworks against built-ins

The entry-point loop in get_available_compliance_frameworks appended
framework names without checking whether the same name was already
provided by a built-in. The loader (Compliance.get_bulk) already
respects "built-in wins" via an explicit guard, but the listing
function did not, causing --list-compliance and
--list-compliance-requirements to print the same name twice on
collision with a built-in.

Adds the same dedup guard already used by the universal frameworks
loop a few lines above, restoring symmetry across the three
compliance discovery layers.

Includes a regression test that registers a fake entry point with
a name colliding with a known built-in (cis_2.0_aws) and asserts
the framework appears exactly once in the resulting list.
