Each SSE frame now includes a sequential numeric id: field. Clients can
reconnect with the Last-Event-ID header to resume the stream after the
last received event, skipping already-processed events.

Add a FeatureFlags config section with a session_sandboxes boolean

Gate the project/branch picker UI behind this flag. Set it to false
in the Docker demo config.

Adapt session detail and sidebar to the new schema: use created_at/
updated_at instead of repo/time, display relative timestamps via a new
timeAgo() helper, and remove repo badges from the UI.

Replace `repo` and `time` with ISO 8601 `created_at`/`updated_at`
timestamps across session schemas. Remove `project`/`branch` from
CreateSessionRequest and add optional `model`. Add descriptions and
examples to all session-related OpenAPI schemas and endpoints.

Add three new pages under a "Using the API" group in the API Reference
tab: API Overview (base URL, authentication, errors, pagination,
versioning), Demo Mode, and Client SDKs. Nest "Run Internals" as an
expandable sub-group under "Run Outputs" in the nav.

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.

Add three end-to-end tests for the GitHub App Installation Access Token clone
flow (private repo clone, public repo optimization, not-installed error). Also
return an error from is_repo_public on non-404 HTTP failures instead of
attempting to parse the response as JSON.

- Share a single reqwest::Client across GitHub API calls in resolve_clone_credentials
to reuse the TLS connection pool
- Accept raw PEM (not just base64-encoded) in build_github_app_credentials, matching
the existing decode_pem_env/decode_pem_value convention
- Move github_app into DaytonaSandbox::new() instead of cloning

Replace `gh auth token` with GitHub App IATs scoped to `contents: read` for
Daytona sandbox git cloning. Public repos are auto-detected and cloned without
credentials. Private repos get short-lived, repo-scoped tokens. Clear error
messages for each failure mode (app not installed, suspended, no repo access,
auth failure). Falls back gracefully when no GitHub App is configured.

Add both models with aliases (gpt54, gpt54-pro). Neither replaces

Per-node `max_visits` now overrides the graph-level `max_node_visits`

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.

- Add follow_up, steering_before_input, and steering_mid_task parity tests
- Add steering_queue_handle() to Session for test access
- Expand provider_tests! macro to cover all 7 providers (Kimi, Zai, Minimax, Inception)

- Fix OpenAI-compatible tool result serialization: emit one ChatMessage per ToolResult
instead of bundling all results into a single message with only the first tool_call_id.
This was causing Kimi to reject requests during parallel tool calls.
