/**

 * Vendor-neutral PreToolUse hook entry. Reads the standard hook JSON
 * payload from stdin and either exits 0 (allow) or exits 2 with stderr
 * containing PEAKS_CODE_PROHIBITED_DIRECT_EDIT (deny).
 *
 * This command is the runtime adapter the shell-script sibling
 * (`src/services/hooks/pre-tool-code-gate.sh`) EXECS. The path-family
 * decision lives in ONE implementation — `decideGateAction` — and the
 * sibling's own no-CLI fallback is a narrower copy of it.
 *
 * Settings.json entry shape (vendor-neutral, registered by
 * `peaks hooks install`): an `Edit|Write|MultiEdit` matcher whose command is
 * `peaks code-gate`, carrying the adapter's own project-root env var and
 * `--json`.
 *
 * The vendor-specific install code (`src/cli/commands/hooks-commands.ts`
 * + `src/services/ide/adapters/*`) is the only place that knows how
 * to render this into any IDE's settings.json shape. This file is
 * vendor-neutral — no vendor references in the source code itself.
