Preflight validation is conceptually distinct from running a workflow —
it deserves its own top-level command rather than being a flag on `run`.
- Add `PreflightArgs` struct and `Commands::Preflight` variant
- Create `commands/preflight.rs` with dedicated `execute()` function
- Remove `--preflight` flag from `RunArgs`
- Refactor `load_workflow_source_input` to take individual params
instead of `&RunArgs`
- Refactor `resolve_cli_goal` to take `Option<&str>` / `Option<&Path>`
- Refactor `run_preflight` to take `cli_model`/`cli_provider` instead
of `&RunArgs`, make `pub(crate)`
- Update docs and skills references

Remove ErrorPolicy enum (continue/fail_fast/ignore) and the k_of_n/quorum
join policies from the parallel handler, leaving only wait_all and
first_success. This deletes ~180 lines of conditional logic including
FailFast early termination, the ParallelEarlyTermination event, and all
related tests and documentation.

- Remove any-edge fallback from select_edge() in deterministic mode; random
mode retains it as an enhancement over the base spec
- Restrict preferred_label and suggested_next_ids matching to unconditional
edges only (already applied in prior work, tests added here)
- Rename default_max_retry → default_max_retries across codebase (code, docs,
fixtures, skills) and change default from 3 to 0
- Update transitions.mdx to document edge selection cascade accurately

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

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.

Port the OpenAI Codex develop-web-game skill (Playwright-based game dev
loop) into skills/develop-web-game/ with paths adapted for Arc's
workspace-relative skill discovery. Add a web-game-demo workflow that
verifies the skill and its asset files (playwright client script,
action payloads JSON) are properly discovered and accessible in a
Daytona sandbox.
