-/**
- * TIA Vite dependency resolver.
- *
- * Spins up a throwaway headless Vite dev server using the project's
- * `vite.config.*`, walks every `resources/js/Pages/**` entry to warm
- * up the module graph, then serializes the graph as a reverse map:
- *
- *   { "<abs source path>": ["<page component name>", ...], ... }
- *
- * The resulting JSON is written to stdout. Stderr is silent on
- * success so Pest can parse stdout without stripping.
- *
- * Why this exists: at TIA record time we need to know which Inertia
- * page components depend on each shared source file (Button.vue,
- * Layouts/*.vue, etc.) so a later edit to one of those files can
- * invalidate only the tests that rendered an affected page. Vite
- * already knows this via its module graph — we borrow it.
- *
- * Called from `Pest\Plugins\Tia\JsModuleGraph::build()` as:
- *
- *   node bin/pest-tia-vite-deps.mjs <absoluteProjectRoot>
- *
- * Environment:
- *   TIA_VITE_PAGES_DIR  override the `resources/js/Pages` default.
- *   TIA_VITE_TIMEOUT_MS  override the 20s internal watchdog.

- * The Laravel `WatchDefaults\Inertia` glob is a broad fallback — fine

- * this armed, each test's recorded edge set grows to include the
- * component names it returned through `Inertia::render()`, and
- * subsequent replay intersects page-file changes against that set.
- *
- * Mechanism: listen for `Illuminate\Foundation\Http\Events\RequestHandled`
- * on Laravel's event dispatcher. Inertia responses are identifiable by
- * either an `X-Inertia` header (XHR / JSON shape) or a `data-page`
- * attribute on the root `<div id="app">` (full HTML shape). Both carry
- * the component name in a structured payload we can parse cheaply.
- *

- * Known limits (intentional — preserving correctness over precision):

- *     `vite.config.ts` are ignored; anything we can't resolve is
- *     simply skipped and falls through to the watch-pattern safety
- *     net.
- *   - Dynamic imports with variable expressions
- *     (`import(`./${name}`.vue)`) can't be resolved; the literal
- *     prefix is ignored and the caller over-runs. Safe.
- *   - Vue SFC `<script>` blocks parsed whole; imports inside
- *     `<template>` blocks (rare but legal) are not scanned.
- *
- * Output shape mirrors the Node helper: project-relative source path
- * → sorted list of component names of pages that depend on it.
