Summary by cubic

Adds a reference note distinguishing Compact (context-window compression) from Dream (long-term memory consolidation) in agent memory stacks, plus a small Neon query type cast in SiteStats.astro so bun run check stays clean.

• The note covers pi's compaction flow—20k recent-token retention, structured summary, incremental compaction across sessions, and split-turn handling.
• It documents Claude's two Dream implementations: AutoDream's background memory-file consolidation and Platform Dreams' async job producing a reviewable new memory store.
• It positions the two as complementary layers—compact frees the window, dream decides what to keep—and notes their own memory stack (incremental appends + mem0 + recaps) lacks the dream layer.
• The SiteStats.astro change casts the neon query result explicitly; behavior is unchanged.

^{Written for commit 56532a3. Summary will update on new commits.}
