Bump to v0.6.0 — article discovery, search, profile tab, reader polish

Article discovery feed with Latest/Following tabs, article search
(NIP-50 + hashtag for kind 30023), Notes/Articles tab on profiles,
reading time + bookmark + like buttons on article reader. Event
passed directly from card to reader to avoid relay re-fetch failures.
