Veridge v0.4.0

Veridge v0.4.0

Added — the open graph

• Versioned schema — graph.json now carries a top-level schema_version, making it a stable public contract. Documented in docs/graph-format.md.
• veridge export — emit the graph for other tools to build on:
  • jgf — JSON Graph Format (generic, tool-friendly),
  • dot — Graphviz (for rendering),
  • native — the canonical graph.json.

So an LLM-comprehension tool, agent, notebook or visualiser can consume Veridge's deterministic structural + ranking layer for free, and spend its own model only on semantics.

Zero runtime dependencies in the core. 93 tests, ruff clean.

Install: pip install -U veridge (or pip install veridge[treesitter]).
