list_skills does not show whether each skill is enabled or disabled #631

Summary

list_skills prints every user-created skill as **name**: description and never shows whether it is enabled or disabled, or whether it failed to load. A model reading the list cannot tell a disabled skill from an available one until invoke_skill refuses it or it checks skill_status per skill.

Evidence (live, 2026-09-30, campaign branch deploy; master 55c15761 formats the list the same way)

• After disable_skill and edit_skill, skill_status correctly reported the skill as disabled.
• list_skills in the same turn returned **live_battery_probe**: Temporary live battery retained-output probe edited while disabled, with no status.
• The formatter is src/discord/native_tools/skills_tools.py, the list_skills branch, which renders only name and description.

Expected

• list_skills marks each skill's state (enabled, disabled, load error), or lists disabled skills separately.
• The model sees availability without extra calls, consistent with the WebUI Skills page after Skills Active Skills count includes disabled and error-state records #531.

Impact

Every install with disabled skills: the model may plan around a skill it cannot use, costing a failed invoke_skill call. Low severity.
