docs: fix ASCII diagram alignment in README

[psimaker]

Cosmetic fix: trailing spaces inside the architecture diagram boxes now line up the right border. No functional change.

Documentation

Fixed spacing and alignment in the "How it works" ASCII diagram in README.md. Trailing spaces within the architecture diagram boxes now properly align the right borders, improving visual consistency of the diagram.

This is a purely cosmetic change with no impact on functionality or behavior.
