/**
 * Unified orchestration env parsing (design/96 §定.2 L1, S7) — the single TOC entry that resolves
 * `ORCHESTRATION_MODE` / `SCENARIO` / `REASONING_INTENSITY` / teacher role names into a structured intent.
 *
 * Honesty: this layer parses INTENT only. It does NOT pick models — env names a model **role**, and the
 * deploy side maps roles to concrete models (the existing model-role体系); we never invent a model env
 * namespace (design/96 第二轮点6). `REASONING_INTENSITY` is validated against the legal {@link ThinkingLevel}
 * tiers (off..max) — an illegal value throws (don't silently swallow it).
 *
 * Three-layer progressive exposure (design/96 §定.2): L0 = no env → the explicit `solo + standard` default
 * (not a blank); L1 = a single env switches to a preset; L2 = a full config object (not this layer's job).
