Add optional name, email, avatar, and denchOrgId fields to
telemetry.json. When present, all telemetry layers (CLI, web server,
web client, OpenClaw plugin) call PostHog identify() with $name,
$email, $avatar, and dench_org_id person properties.
Remove $process_person_profile:false from all layers so every install
gets a PostHog person profile. Enable session replay with masking
controlled by privacy mode (all text/inputs masked when on, nothing
masked when off).
