v0.4.31

Features & Fixes

• #488 Legacy edge/node schema canonicalization — source→source_file on nodes, from/to→source/target on edges now handled before validation
• #482 Java inheritance — extends, implements, and interface-extends edges now extracted from AST; two-pass cross-file import resolver emits real imports edges instead of silently dropping them
• #472 Aggregated HTML view for large graphs — corpora >5000 nodes now get a community meta-graph in graph.html instead of no output at all; updated in both skill.md and skill-opencode.md
• #490 graphify check-update <path> — cron-safe CLI subcommand that checks for pending semantic updates and notifies without running LLM extraction

441 tests passing.
