Number section files to match reading order ...

sections/*.tex renamed to 1_introduction.tex .. 6_conclusion.tex so the
directory listing sorts in the same order they're \input from main.tex.
No 0_abstract.tex: the abstract must stay inline in main.tex (mdpi.cls
reuses it as PDF pdfsubject metadata, which \input breaks), and a
drafting-only file would just duplicate it with a risk of drifting out
of sync, so CLAUDE.md now says so explicitly.

Split manuscript body into main.tex + sections/, move template to Template/ ...

main.tex is now the actual manuscript to edit and compile, copied from
the official MDPI template. Body content moves out into
sections/{introduction,related_work,method,experiment,discussion,
conclusion}.tex, \input from main.tex right after each \section heading;
figures/ added for images. Abstract stays inline in main.tex since
mdpi.cls reuses it verbatim as PDF pdfsubject metadata, which requires
full expandability that \input breaks.

The pristine template (template.tex/template.pdf) moves into its own
Template/ folder to stay visually distinct from the actual manuscript;
its \documentclass/\includegraphics calls are updated to ../Definitions/
accordingly. It's kept as read-only reference going forward.

Also removes the template's "How to Use this Template" placeholder
section and the unused optional Patents section, and documents the new
layout in CLAUDE.md.
