Add configurable case-insensitive search

- Add MEM0_CASE_INSENSITIVE config option (default: false)
- When enabled, searches with both original and lowercase query
- Merges results, keeping highest score for each memory
- Fixes case sensitivity issues with Qdrant embeddings
- Generalize after-install.md with placeholders instead of personal values
