Add markov, emojiboard, achievements, miniflux plugins and adventure catch-up fix

New plugins: encrypted Markov chain generation (9 commands), emojiboard
reaction stats (5 views), Miniflux RSS feed integration (8 commands),
and 48 new achievements across 9 categories. Adventure startup now
unconditionally resets daily actions and respawns expired deaths to
handle missed resets from SQLite contention. README updated with all
new features.
