Consolidates server-mode documentation into a single page with
standalone vs. server comparison table, setup guide, and cross-references.
Updates how-arc-works, quick-start, and architecture pages to link to
the new canonical page instead of duplicating the comparison table.

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.

The local .env loading was unnecessary since arc install writes all
config to ~/.arc/.env. Simplifies dotenv behavior to unconditionally
load from the home directory only.

The one-time environment setup command (LLMs, certs, GitHub) is now
`arc install`, freeing up naming space for a future `arc init` command
for per-project initialization.

Per-run data now lives in ~/.arc/runs/ while daily CLI log files
stay in ~/.arc/logs/. Renames: logs_root → run_dir (RunConfig field,
Handler trait param, all handlers), logs_dir → run_dir (CLI arg,
local variables), default_logs_base → default_runs_base (path fn).
Adds DB migration 002 to rename workflow_runs.logs_dir → run_dir.

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").

Add Backends section to agents page explaining the two execution
strategies, expand backend attribute descriptions in dot-language
and stylesheet references, and add API-only notes to tools and
sub-agents pages.
