Optimize HTMLTree to_tuple conversion using Enum.reduce

[preciz]

Replaced Enum.reverse() |> Enum.map() with a single-pass Enum.reduce/3, eliminating double traversal for a performance and memory improvement.

Summary of Improvements

• Big Input: ~42% faster (4.33 ms vs 6.16 ms), memory reduced by ~18% (1.39 MB vs 1.70 MB).
• Medium Input: ~13% faster (578 μs vs 652 μs), memory reduced by ~14% (481 KB vs 562 KB).
• Small Input: ~13% faster (65 μs vs 74 μs), memory reduced by ~16% (97 KB vs 116 KB).
