[FEATURE] Add Skill() to permissions pattern in JSON schema

Problem

The JSON schema at https://www.schemastore.org/claude-code-settings.json doesn't include Skill in the permissionRule regex pattern. This causes false validation errors when users add skill permissions to their settings.

The current regex pattern includes:

Bash|BashOutput|Edit|ExitPlanMode|Glob|Grep|KillShell|NotebookEdit|Read|SlashCommand|Task|TodoWrite|WebFetch|WebSearch|Write

But Skill is missing, so entries like these fail validation:

• Skill(codex-oracle)
• Skill(dry-refactor)
• Skill(fp:effect-ts)
• Skill(frontend:xstate-react)

Proposed solution

Add Skill to the tool list in the permissionRule pattern:

- Bash|BashOutput|Edit|ExitPlanMode|Glob|Grep|KillShell|NotebookEdit|Read|SlashCommand|Task|TodoWrite|WebFetch|WebSearch|Write
+ Bash|BashOutput|Edit|ExitPlanMode|Glob|Grep|KillShell|NotebookEdit|Read|Skill|SlashCommand|Task|TodoWrite|WebFetch|WebSearch|Write

Alternatives considered

Users can disable schema validation, but that loses the benefit of catching actual typos and invalid patterns.
