Subject: [PATCH] Fix ranking and add detailed language analysis

- Fixed ranking: now sorted by time, then memory (lower = better)
- All ranks are unique (1-32), no duplicates
- Added detailed analysis for all 32 languages
- Explained why each language performs as it does
- Included implementation details and memory usage reasons
- Sorted by performance: fastest to slowest

Ranking corrections:
- Odin: Rank 1 (19 ms, fastest)
- Assembly: Rank 2 (20 ms, 1.4 MB, most efficient)
- Nim: Rank 3 (20 ms, 1.5 MB)
- Rust: Rank 4 (20 ms, 1.6 MB)
- Lua: Rank 5 (20 ms, 2.1 MB)
- TypeScript: Rank 32 (931 ms, slowest)
