Mixed line endings: .editorconfig says LF but most .cs files are CRLF, no .gitattributes

[drusteeby]

The repo's .editorconfig declares end_of_line = lf, but most .cs files (inherited from the upstream fork) are CRLF — several with mixed endings within a single file (e.g. src/PluginNodes/Boiler2PluginNodes.cs, src/SimpleEvent/SimpleEventsNodeManager.cs before #21). There is no .gitattributes, so nothing enforces either convention.

Consequences:

• Editors that honor .editorconfig write LF into CRLF files, producing mixed-ending files.
• Any tool that rewrites a whole file normalizes it one way or the other, producing diffs where dozens of untouched lines show as changed with no visible difference (this bit PR Fix CWD-relative resource paths; add screenshot and docker quick start #21).

Suggested fix:

1. Add .gitattributes with * text=auto and *.cs text eol=lf (aligning with .editorconfig), plus appropriate binary entries (*.uanodes, images).
2. One-time renormalize commit: git add --renormalize .

Best done as a standalone PR while few branches are in flight, since the renormalize commit touches most files.
