Rename `llm_model` → `model` and `llm_provider` → `provider` in stylesheet
properties, accessor methods, and all DOT/doc references. Add

catalog, eliminating redundant provider declarations in stylesheets.

Revert the graphviz language identifier back to dot (Shiki doesn't
bundle either) and register a custom TextMate grammar via Mintlify's
styling.codeblocks.languages.custom config. The grammar (extracted from
apps/arc-web/app/data/dot-grammar.ts) highlights keywords, shape names,
attributes, strings, comments, and operators.

Changes ```dot to ```graphviz across all docs for better syntax highlighting
in Mintlify (Shiki). Full digraph blocks get a title derived from the workflow
name (e.g. title="hello.dot").
