Gate 2c/quality finding (Low): when some -s skills loaded, cli.py,
hermes_cli/oneshot.py and tui_gateway/server.py still logged "Unknown
skill(s) requested, skipping: Ambiguous skill name dup-demo: ..." --
calling an ambiguous name unknown, the exact wording 3b6f5eb813 removed
from the all-missing error. All three now log format_missing_skills(),
and the "Ambiguous skill name " prefix lives in one constant
(agent.skill_utils.AMBIGUOUS_SKILL_PREFIX) shared by the skill_view
error, the preload/cron label and format_missing_skills' classifier.
