feat: curiosidades plugin for stat-based server announcements

Announces a random Portuguese fact about a random online player on a
timer, sourced from vanilla statistics, with clickable reactions.

Block/item/mob names are emitted as translatable components so each
client renders them in its own language instead of shipping a
translation table. Sentences are phrased to avoid number agreement with
the translated noun ("5.966 blocos de Pedra", not "5.966 Pedras").

Statistic constants are resolved by name with fallbacks because they get
renamed across Minecraft releases; a rename degrades one curiosity
rather than breaking the announcement.

Chat cannot be edited after sending, so live reaction tallies ride on a
boss bar while the in-chat buttons stay frozen at send time.
