Fix PlatformLinkTag.parse() off-by-one bug where tag indices were shifted (platform/uri/entityType read from wrong positions). Add missing TagArrayExt and EventExt files for definition and recommendation packages to align with the modern pattern used by nip88Polls. Parameterize DiscoverNIP89FeedFilter by targetKind and create NIP-89 poll app discovery infrastructure linking NIP-88 polls (kind 1068) to the NIP-89 app handler discovery system. https://claude.ai/code/session_013r2LXj11SieWa5PaLesKfC
