Roadmap: replace placeholder items with current shipped/building/planned
features. Use real dates for sorting instead of manual sortOrder. Fix
UTC timezone rendering for date display.
Terminology: replace all standalone "DOT" references with "Graphviz" or
"Graphviz DOT" across docs, marketing, README, AGENTS.md, and OpenAPI
spec. Changelogs left unchanged as historical records.

Note in stylesheets, DOT reference, multi-model tutorial, run config,
and skill references that provider is now optional and auto-inferred.
Remove redundant provider from TOML examples.

Rename `llm_model` → `model` and `llm_provider` → `provider` in stylesheet
properties, accessor methods, and all DOT/doc references. Add
ProviderInferenceTransform that automatically infers provider from the model
catalog, eliminating redundant provider declarations in stylesheets.

Regenerate 2026-03-10 changelog with full commit set (installer, devcontainer
support, arc pr subcommands, --no-dotenv removal). Add 2026-03-11 changelog
for shadow branch run records and arc diff improvements. Update docs: CLI
reference (arc pr list/view/merge/close, --shortstat), devcontainers page
(replace placeholder with full content), run-configuration (devcontainer
field), checkpoints (per-node files on metadata branch), models catalog
(gemini-3.1-pro-preview-customtools). Improve preflight to show per-model
LLM checks instead of a single merged provider line.

Every TOML example now shows which config file it belongs to
(server.toml, cli.toml, or run.toml) via Mintlify's title annotation.

Add both models with aliases (gpt54, gpt54-pro). Neither replaces
gpt-5.2 as the OpenAI default. Update fallback chain test since
GPT-5.4 ($2.50) is now closer to Opus ($15) than GPT-5.2 ($1.75).

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").
