📣 erdify 0.7.0 — JSON & HTML output

[FabianClemenz]

Two fresh output formats land in 0.7.0, on top of a big 0.6.0:

New in 0.7.0

• 🧾 --format json — the parsed model as structured JSON, so other tools can build on erdify's output (the foundation for the
  interactive viewer idea 👀).
• 🌐 --format html — a self-contained page that renders the ERD with Mermaid. Generate, double-click, done.

--format takes several at once — e.g. erdify . -o docs/erd --format plantuml mermaid json html writes all four side by side.

Recap — 0.6.0

• 🧜 Mermaid output (renders natively right here in GitHub markdown)
• 🐘 Django ORM support (incl. TextChoices/IntegerChoices enums)
• ⚙️ [tool.erdify] config in pyproject.toml + --check for CI/pre-commit drift
• ⚠️ Minimum Python is now 3.11

pip install --upgrade erdify    # Python >= 3.11

Still zero runtime dependencies, still pure-AST (no DB connection, no imports).
