/**
 * Parsing + decision logic for Claude Code's hardcoded safety prompts.
 *
 * `--dangerously-skip-permissions` does NOT suppress every prompt. Claude Code
 * keeps a small set of "circuit breaker" safety checks that always ask, no matter
 * what the permission mode is — the CLI says so itself: "This requires explicit
 * approval and cannot be auto-allowed by permission rules." Confirmed kinds in
 * claude 2.1.220: `dangerousRemoval` (e.g. `rm -rf "$VAR/$d"`, which becomes
 * `rm -rf /*` when VAR is empty), `backgroundOperator` (`&`), and
 * `suspiciousWindowsPath`.
 *
 * These render as a select box in the TUI:
 *
 *     Dangerous rm operation on possibly-empty variable path: "$W4/$d"
 *
 *     Do you want to proceed?
 *     ❯ 1. Yes
 *       2. No
 *
 *     Esc to cancel · Tab to amend · ctrl+e to explain
 *
 * A gateway-driven PTY has nobody at the keyboard, so the turn hangs forever.
 * Two things were verified against a live PTY before this module was written:
 *   1. a PreToolUse hook returning `permissionDecision: "allow"` does NOT
 *      dismiss it — hooks cannot pre-approve a circuit breaker, so answering the
 *      TUI is the only route; and
 *   2. the `Notification` hook DOES fire (~6s later) with
 *      `notification_type: "permission_prompt"` — that is the detection signal.
 *
 * Everything here is pure: viewport text in, a decision out. The parser is
 * deliberately strict — it would rather return null and let the turn stall than
 * fire keystrokes at a dialog it does not fully recognise.
