docs: fix drift in best-practices/memory-rules (#250)

- Correct the src/index.ts line reference for expansion params
  (764-811, not 350-355) to match current mcp-automem main.
- Update the Two-Phase Recall example to match the current
  CLAUDE_MD_MEMORY_RULES.md template: Phase 1 now uses limit 20 +
  sort: "updated_desc"; Phase 2 uses a single query (not queries[] +
  auto_decompose) with a 90-day window and limit 30, per the
  template's own validated tradeoffs note.

-Don't mix tag-based preference recall with semantic task recall — combining them dilutes results. Preferences are stable and should use exact tag matching without semantic search interference.
+Don't mix tag-based preference recall with semantic task recall — combining them dilutes results. Preferences are stable and should use exact tag matching without semantic search interference. For Phase 2, a single well-written `query` consistently beats `queries[]` + `auto_decompose: true` on focused tasks; reserve multi-query decomposition for genuinely multi-topic questions.
