Combining both PRs for issue #92993: #93149 makes set_pinned() return a
bool and _cmd_pin/_cmd_unpin exit 1 on a no-op write; #93002's tests
stubbed set_pinned with a None-returning lambda, which the combined
_cmd_pin now reads as failure. The stub reports True (write landed) so
#93002's messaging assertions exercise the intended success path.
`hermes curator pin` guarded on is_agent_created (a filesystem-shape
check), but the flag only matters when the skill carries the
curator-management marker: curated_report() walks marker-carrying skills
only, so auto-transitions never consider an unmanaged (pre-marker)
skill at all. Pinning one recorded the flag and then printed
"will bypass auto-transitions" — an effect that does not exist.
Keep the write (the flag becomes meaningful after `hermes curator
adopt`) and branch the message on is_curator_managed: unmanaged pins
now say the skill is unmanaged and point at adopt. Unpin gets the
symmetric wording.
