v2.1.0

New features

• Plain-text output format (--text / format="text") for both call-graph and module-level modes. Sorted adjacency list with [D]/[U] edge tags.
• del statement protocol tracking — del obj.attr now generates a uses edge to __delattr__, and del obj[key] to __delitem__.
• Iterator protocol tracking — for loops, async for loops, and comprehensions now generate uses edges to __iter__/__next__ (or __aiter__/__anext__ for async).
• Local variable noise suppression — visit_Name no longer creates wildcard UNKNOWN-flavored nodes for local variables with no resolved value.
• Positional matching for starred tuple unpacking — a, b, *c = x, y, z, w now binds a→x, b→y, *c→{z, w} instead of the previous Cartesian product.
• --version CLI flag.

Bug fixes

• Fix --defines being off by default due to an argparse quirk.

Documentation

• Reorganized README with table of contents.
• Python API example for call-graph mode.
• Updated Features section with all v2.0+ additions.
• Consolidated inline TODO items into TODO_DEFERRED.md.
• New synthetic showcase graph (orbital mechanics theme) demonstrating uses edges, self-recursion, mutual recursion, HSL coloring, and namespace grouping.

Housekeeping

• Bumped actions/checkout to v6, actions/setup-python to v6.
