Bryan Helmkamp 15cf4d8640 refactor: wire vendored Graphviz into fabro-graphviz, remove dot dependency ... Replace the Command::new("dot") shell-out in render_dot() with a direct FFI call to the vendored Graphviz library. Drop PNG support (SVG only). Remove GraphFormat enum, dot_is_available() helpers, dot-related diagnostics/doctor checks, and the graphviz install prompt. Update OpenAPI spec to remove png format and 502 responses. Update CLI help text, snapshot tests, and documentation. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>		2026-04-13 22:46:29 -04:00
