Add GraphBuilder 1.0.7 (x64)

[pisarev]

GraphBuilder plots the formula under your mouse. Alt+G opens a docked panel;
point at a line of the file and, if it parses as a formula, the curve is drawn
with its roots, intersections and extrema marked. A selection wins over the
line, and whatever comes from the editor keeps a slot of its own, so pointing
around does not fill up the list.

The report goes back the other way: one button puts it in a new tab as Markdown,
with the curve embedded as SVG so it stays text in a text editor, and another
drops the same report at the caret.

The panel is a web page in WebView2 and the computing is Object Pascal. The same
page runs as a browser demo
with the engine compiled to WebAssembly, so the plugin can be tried without
installing it.

Built with Lazarus and Free Pascal; the sources and the build script are in the
repository, so the DLL can be reproduced without a commercial compiler.

• x64 only.
• Requires the WebView2 runtime: it ships with Windows 11 and arrives with Edge
  on Windows 10.
• Installed and used locally on Notepad++ 8.9.3, 64-bit: the panel opens, picks
  a formula off a line, draws it, and returns the report to the editor both ways.
