chore: add UTM parameters to altimate.ai website links

Tags the 6 user-facing marketing-website links (utm_source=altimate-code,
utm_medium=github|docs|marketplace) so npm/GitHub/docs-driven traffic is
attributable in analytics. Deliberately untouched: provider HTTP-Referer
headers, $schema/config.json URLs, github/index.ts API base URL,
CHANGELOG, and other Altimate properties (help.altimate.ai, altimate.sh,
altimate.studio).
