/**
 * [WHO]: ApprovalSelectorComponent, ApprovalDecision, ApprovalChoice, CliApprovalClient, APPROVAL_TIMEOUT_MS
 * [FROM]: Depends on @catui/tui, ../theme/theme.js, node:process
 * [TO]: Consumed by modes/interactive/interactive-mode.ts (ApprovalSelectorComponent, Layer 2 TUI surface) and
 *   main.ts (CliApprovalClient, Layer 2 runtime wire) — both honor ADR bash-pre-execution-approval-decision.
 * [HERE]: modes/interactive/components/approval-selector.ts - TUI selector + minimal CLI client for
 *   dangerous bash commands. ApprovalSelectorComponent is the polished Layer 3 surface; CliApprovalClient
 *   is the Layer 2 wiring proof-of-life (does not mount to TUI, reads stdin directly + 60s timeout -> deny).
