feat(easter-eggs): add easter egg hunt addon across all worlds

50 eggs hidden per child world (Jamie/Lyla/Mya) in 8 creative hiding
scenes (barrels, hay bales, flower patches, logs, fences, crafting
tables, mossy ledges, leaf clusters). Each world uses a distinct glazed
terracotta colour. Found eggs are tracked via player tags which persist
across server transfers; lobby reads tags and maintains a scoreboard
leaderboard (egg_count objective). Gitea deploy workflow updated to
include easter-egg-addon/ and docker-compose.yml in checkout.
