Repository dependency and priority graph

Understand code dependencies and prioritize feature work.

Generate a dependency graph and priority report:

arka repo_graph .
arka repo_graph . --format json --output repo-graph.json
arka repo_graph . --format mermaid --output repo-graph.mmd

The report scans supported Python imports, counts dependent files, and combines that centrality with TODO/FIXME markers. High-centrality files are surfaced first because changes there affect more of the repository. This is a planning signal, not a substitute for product impact, security review, or tests.

Natural language works: “show the repository dependency graph and priorities.”
