/**
 * Resolve the first-time "install peaks hooks" decision for this project.
 * Decision tree:
 *
 *   1. Read the sticky marker.
 *      - Marker present:
 *        - marker.decision === 'installed' AND hooks are present → action: marker-honored, no side effects
 *        - marker.decision === 'installed' AND hooks are MISSING   → re-install, action: reinstalled
 *        - marker.decision === 'skipped'                            → action: marker-honored, no install
 *      - Marker absent:
 *        - hooks already present → write a fresh 'installed' marker, action: already-installed
 *        - otherwise:
 *          - explicit --install-hooks=auto  → install + marker, action: first-decision
 *          - explicit --install-hooks=skip  → marker only, action: first-decision
 *          - explicit --install-hooks=ask OR default in TTY:
 *              - jsonMode → silently auto-install (LLM cannot answer), action: first-decision
 *              - TTY      → prompt; on yes install + marker, on no marker-only
 *          - default in non-TTY → auto-install, action: first-decision
 *
 * Project scope is the only supported scope here; global scope is reserved
 * for explicit `peaks hooks install --global` invocations.
