…clicks Add passive event capture for form submissions and outbound link clicks, firing as TrackMessage events with surface: 'pixel'. Both use single document-level listeners (event delegation) and respect consent state. Form submissions capture formAction, formId, formName, fieldNames, and at full consent, SHA-256 hash email values client-side before enqueuing. Outbound link clicks capture linkUrl, linkText, elementId, outbound flag. Both configurable via autocapture init option. Bundle impact: ~0.5KB gzipped (total pixel bundle: 4.1KB gzipped).

When crypto.subtle is unavailable (HTTP pages, some privacy browsers, Safari <15 non-secure contexts), enqueue form_submitted without emailHash rather than silently losing the event entirely. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Summary
Implements SDK-52: passive event capture for form submissions and outbound link clicks — the two most valuable conversion signals the pixel can collect without any studio instrumentation.
submitlistener capturesformAction,formId,formName,fieldNames. Atfullconsent, SHA-256 hashes email values client-side before enqueuing (raw email never enters the queue). Atanonymous, captures form metadata only. Silent atnone.clicklistener targets<a>tags where hostname differs fromwindow.location.hostname.
