Subject: [PATCH 1/4] feat: track website_email_submit in PostHog on email form
 submit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Capture a website_email_submit event in PostHog when a user successfully
submits the email signup form, mirroring the Common Room notify timing but
without the email address — only that a submission happened. Attach the
Common Room visitor id (signals-sdk-user-id cookie) as both an event and
person property so the two systems can be joined per visitor.

Subject: [PATCH 2/4] feat: identify PostHog person by Common Room id on email
 submit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Under person_profiles: 'identified_only' a bare $set on an anonymous
visitor is dropped, so attach the Common Room visitor id via
posthog.identify() instead — this creates the person profile and keys it
to Common Room. Still capture website_email_submit so the conversion is
recorded even without a Common Room id. No email is sent to PostHog.

Subject: [PATCH 3/4] feat: identify PostHog person by email on submit, retry
 Common Room cookie

Record the email in PostHog and identify the person by it (the key Common
Room also de-anonymizes on), attaching the Common Room visitor id when
present so the two systems join per visitor. Common Room writes its
signals-sdk-user-id cookie asynchronously, so if it's absent at submit time
wait 2s and retry once before recording without it. The submission is
always recorded either way, with or without the Common Room id.

Subject: [PATCH 4/4] refactor: drop deferred Common Room id lookup on email
 submit

Read the signals-sdk-user-id cookie once at submit time and fire
identify + capture immediately, instead of waiting 2s and retrying when
the cookie is absent. If Common Room hasn't written the cookie yet we
simply record without common_room_user_id.
