…n_build() Extracts the build() pipeline body into a private async helper _run_build() that accepts an already-constructed BuildConfig. Rewrites build() as a thin wrapper over _run_build() with identical behaviour. Adds fast_build() as a new @app.reasoner() with the same 10-parameter signature that merges 12 speed-optimised defaults before any caller-supplied config overrides, then delegates to _run_build(). All changes confined to swe_af/app.py. Fast defaults: max_review_iterations=0, max_retries_per_issue=0, max_replans=0, enable_replanning=False, max_verify_fix_cycles=0, max_coding_iterations=1, max_advisor_invocations=0, enable_issue_advisor=False, enable_integration_testing=False, agent_max_turns=50, agent_timeout_seconds=900, git_init_max_retries=1.
