Embeds the ULID run_id directly in the directory name so logs dirs
can be easily correlated with runs.

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

Commands can now delegate to a running Arc API server instead of
executing in-process. Adds ExecutionMode, ServerDefaults, and
ClientTlsConfig to cli.toml parsing with CLI flag > config > default
precedence. The models list command fetches from GET /models when in
server mode, with mTLS client certificate auth when [server.tls] is
configured.

Enrich the entire OpenAPI spec with descriptions, examples, format
annotations, extracted parameters, discriminated unions, and richer
response schemas — matching the patterns already established for
Sessions.
Structural changes:
- Extract CancelRunResponse and SteerRunResponse from inline schemas
- Change POST /runs/{id}/steer from 200 to 202 (async fire-and-forget)
- Split StageTurn into discriminated union (SystemStageTurn,
AssistantStageTurn, ToolStageTurn) with oneOf + discriminator
- Add status + created_at to StartRunResponse
- Add created_at to RunListItem and RunStatusResponse
- Add created_at + updated_at to SavedQuery
- Add format: date-time on RetroListItem.timestamp
- Extract 7 new reusable parameters (StageId, QuestionId, WorkflowName,
VerificationSlug, InsightQueryId, ProjectId, CheckpointFilter)
- Enrich existing RunId, PageLimit, PageOffset parameters
- Add descriptions + examples to all ~66 schemas and ~200+ properties
- Add operation descriptions to all ~35 endpoints
Rust handler updates:
- Change ManagedRun.created_at from Instant to chrono::DateTime<Utc>
- Populate new fields in StartRunResponse, RunStatusResponse
- Use new StageTurn discriminated union variants in demo data
- Update demo data timestamps to use DateTime<Utc>

Replace the server-level `--demo` flag with per-request demo dispatch.
The Rust API builds both a demo and real router; incoming requests with
the `X-Arc-Demo: 1` header hit the demo router (auth disabled, static
data), all others hit the real router with normal auth.
The React web app gets a beaker icon toggle in the top nav bar (next to
the theme toggle) that sets an `arc-demo` cookie. Loaders read the
cookie to decide whether to send the `X-Arc-Demo: 1` header to the API.
The `ARC_DEMO=1` env var still works as a default when no cookie is set.

Per-node `max_visits` now overrides the graph-level `max_node_visits`
(and the dry-run default of 10) for individual nodes, giving tighter
control over specific loops like fix-and-verify cycles.

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").
