v1.1.5 - Skill sync lint and AI summaries

Highlights

• Adds scripts/check_skills_sync.py to verify authoritative skills, packaged skills, agent descriptors, summary mirrors, and registered-tool references.
• Implements write_ai_summary=true for pipeline item import, MinerU parsing, and collection ingestion while preserving non-empty user summaries.
• Thins obsidian-views into a research-view skill that delegates Canvas/Bases/Markdown syntax to Kepano/Obsidian format skills and installs them into .claude/skills when missing.
• Adds small eval scenarios across all bundled skills.
• Bumps package/plugin version to 1.1.5 and refreshes release artifacts.
