New roadmap landings and head-to-head comparison pages

The marketing site has new landings dedicated to the roadmap product specifically (vs. the broader "feedback platform" pitch) plus head-to-head comparison pages against the most-mentioned alternatives. Each landing has its own hero variant, feature matrix, and FAQ — no shared templates this time.

For visitors searching "public roadmap tool" or "alternative to X", the new pages should be a much closer match than the generic homepage. Conversion from those keyword clusters has been a known weak spot and this is the structural fix.

Sitemap and hreflang were updated alongside the new pages so search engines pick them up cleanly.
