v0.4.25

Fixes

• report.py: Complete empty-community fix — Community Hubs navigation now skips empty-community entries, Summary line reflects non-empty community count, Knowledge Gaps excludes zero-node clustering artifacts (extends the Communities section fix from v0.4.24)
• main.py: Added graph-query CLI rule to CLAUDE.md, AGENTS.md, and GEMINI.md install sections — agents now know to prefer `graphify query`, `graphify path`, and `graphify explain` over grep for cross-module questions; added MCP CLI fallback line to Antigravity rules
