feat(site): human-language 'what you can do' features section

Add a features section to the landing home (EN/ES) that describes what
Tane does by intent, not mechanism: inventory, care & calendar, labels &
backup, and the neighbourly sharing layer (offers, chat, trust, plantaré,
sync). Follows the existing pillars/values pattern (front-matter data +
template + CSS, RTL-safe). Reframe the beta status copy so the sharing
layer reads as 'arriving, in beta' rather than 'being built'.
