/**
 * Dependency-light stdin reader for hook consumers.
 *
 * Lives in utils (no analyzer/LLM imports) so latency-sensitive hooks — `orient` and the
 * `panic-check` PreToolUse guard — can read the hook payload without pulling a heavy import graph
 * into process startup.
 */
/**
 * Read all of stdin (the hook payload). Resolves '' when stdin is a TTY (nothing piped).
 * Exported for testing; defaults to `process.stdin`.
 *
 * Load-bearing for the "a hook must never hang the user's turn" contract: when the fallback timer
 * fires (a writer that opened the pipe but never wrote/closed it), `done()` not only resolves but
 * TEARS DOWN the stream — pausing it, detaching listeners, and unref-ing the underlying handle — so
 * the process can exit immediately instead of waiting for an EOF that may never come. Resolving the
 * promise alone is not enough: a still-referenced, flowing stdin keeps the event loop alive until
 * the writer closes the pipe.
