Add aria-label to Auto-included badge for screen reader announcement

[Copilot]

The "Auto-included" badge in the skill/tool/plugin library panel has tooltip text that is not announced by screen readers (VoiceOver), violating WCAG 4.1.2 (Name, Role, Value).

• Added aria-label to the EuiBadge in LibraryToggleRow that concatenates the badge label, tooltip title, and tooltip body so the full context is announced on focus

<EuiBadge
  tabIndex={0}
  color="hollow"
  aria-label={
    [disabledBadgeLabel, disabledTooltipTitle, disabledTooltipBody]
      .filter(Boolean)
      .join('. ') || undefined
  }
>

This is in the shared library_toggle_row.tsx component, so it applies to all three library panels (skills, tools, plugins).

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• ci-stats.kibana.dev
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node scripts/eslint x-pack/platform/plugins/shared/agent_builder/public/application/components/agents/common/library_toggle_row.tsx (dns block)
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node node scripts/type_check --project x-pack/platform/plugins/shared/agent_builder/tsconfig.json (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
