/**
 * pi-until-done — Pi-led "/until-done" extension.
 *
 * Replicates Hermes Agent's `/goal` (Ralph loop with judge) on top of Pi,
 * using every Pi primitive and deferring every judgment to Pi itself.
 *
 * This file is the thin composition root. The implementation is split across
 * `extensions/lib/**` per the operating contract: every file ≤200 LOC,
 * every construct ≤30 LOC, nesting depth ≤3.
 *
 * Pi philosophy: hooks COMPOSE — every handler returns `undefined` when it
 * has no opinion so other extensions stay in charge of their own surface.
 * `before_agent_start` appends to (never replaces) the system prompt.
 * `session_before_compact` appends to (never replaces) `customInstructions`.
 * `tool_call` only blocks when the user's ask-before list explicitly fires.
