Add bench/arm.ts, the per-arm scaffolding that produces the single arm definition the runner consumes. Every arm shares an identical task-agnostic base prompt and the same repository coordinates and token; each arm then receives a minimal, symmetric bootstrap. The deliberate asymmetries follow the shipped products: the gitea-axi arm embeds the bundled Agent Skill (its body, charging its ambient cost to gitea-axi); the tea and raw-api arms get a one-line native-discovery pointer; the gitea-mcp arm runs with the shell disabled and only the MCP server attached, its dispatcher schemas loading eagerly. Shell arms' PATH and guard come from bench/guard.ts.
