/**
 * node-pty 1.1.0 publishes its macOS/Linux `spawn-helper` prebuilt binary
 * WITHOUT the execute bit (mode 0644 in the tarball). node-pty execs that
 * helper via posix_spawnp for every PTY it opens, so without +x every spawn
 * dies with `Error: posix_spawnp failed.` — which silently breaks the daemon,
 * since it runs every shell / Claude / Gemini / Codex session through node-pty.
 *
 * We cannot rely on install-time fixes: node-pty's own scripts only touch the
 * from-source `build/Release` path (never the prebuild), and npm 11.17+ blocks
 * postinstall scripts by default (`allow-scripts`), as does `--ignore-scripts`.
 * So restore the bit here, at daemon startup, before any PTY is opened.
 * Idempotent and best-effort.
