/**
 * Task-scoped context injection (change: add-task-scoped-context-injection).
 *
 * `openlore orient --inject` is wired by `openlore install` as a per-task
 * pre-turn hook (Claude Code `UserPromptSubmit`). It runs `orient` for the
 * user's submitted prompt and emits a bounded, OpenLore-attributed, explicitly
 * ignorable orientation block to stdout, so the agent's first turn begins
 * already oriented to the task — amortizing the per-task `orient` round-trip to
 * zero rather than optimizing it.
 *
 * The block is a presentation-and-gating wrapper over the existing lean `orient`
 * output (Spec 27); there is no second orientation code path. It is deterministic
 * (no LLM), framed as facts-not-coercion (Epistemic Lease, decision 8e95746d),
 * and capped by a token budget so it can never dominate the context it economizes.
 *
 * Fail-open is load-bearing: a hook must never break the user's turn. Any
 * failure — missing graph, parse error, empty match, weak match, or empty
 * prompt — degrades to a single pointer line and exits 0.
