fix(skills): отключена блокировка auto-invoke для brainstorm-with-docs

- Зачем:
  - навык должен автоматически вызываться по описанию, а не только вручную.
- Что:
  - удалена опция disable-model-invocation: true из frontmatter.
- Проверка:
  - git diff — изменения только в SKILL.md.

 name: brainstorm-with-docs
 description: Structured brainstorming and design alignment for unclear technical problems, grounded in the project's existing docs and vocabulary — questioning assumptions, sharpening terminology, comparing options, and reaching shared understanding and a recommended direction. Use when exploring an ambiguous engineering, DevOps, architecture, migration, integration, research, or documentation problem; the understanding is the deliverable, recorded in the smallest durable artifact (spec, ADR, runbook, research note, or CONTEXT.md glossary update). Not for implementation, trivial fixes, or executing an already-approved plan.
