v1.1.3 — Canvas layout algorithms, obsidian-ai-summary skill, MinerU rename fix

Changes

New skill: obsidian-ai-summary

• Three trigger modes: explicit request, post-import prompt, pipeline flag write_ai_summary=true
• Source priority: MinerU full-text > literature note
• Standard 5-section template: Core Finding / Method / Dataset / Limitations / My Assessment
• Non-destructive write-back (preserves all other sections)

obsidian-views — Canvas upgrade

• Kepano json-canvas skill detection (reference-first with built-in fallback)
• Concrete layout formulas: Grid, Radial, Layered (DAG topological sort), Grouped
• Bounding-box overlap detection algorithm
• Color table, node size guidelines, ID generation rules
• Pure-JSON visual validation steps (no MCP required)

Cross-skill references

• obsidian-zotero, obsidian-mineru, obsidian-vault now point to obsidian-ai-summary skill

Bug fixes (MCP server)

• Path.rename() → Path.replace(): idempotent, overwrite-safe on Windows (no WinError 183)
• parse_with_mineru: wrap rename call in try/except so extraction status is always persisted
