Move rage click and dead click detection (35% of script.js) into
script.frustration.js as an optional add-on. Core script drops from
8.1KB to 5.7KB gzipped. Add-on auto-discovers core via window.pulse
polling and supports opt-out via data-no-rage/data-no-dead attributes.
- Expose cleanPath on window.pulse for add-on consumption
- Add script.frustration.js to middleware PUBLIC_ROUTES
- Update integration guides, ScriptSetupBlock, and FrustrationTable
empty state to reference the add-on script
