fix(nodes): enforce LF for .md files and harden doc generator on Windows

[joshuadarron]

Summary

• Adds *.md text eol=lf to .gitattributes so git never checks out Markdown files with CRLF on Windows.
• Hardens injectBlock in nodes/scripts/gen-node-tables.mjs to normalize \r\n → \n before diffing, making nodes:docs-generate idempotent on Windows regardless of what line endings git placed on disk.

Problem

On Windows, * text=auto in .gitattributes caused git to check out .md files with CRLF. The doc generator reads CRLF, splices in a generated block built from JS template literals (LF only), and writes back a mixed-ending file. Because the content always differed from the original, every build rewrote the file and left it permanently dirty in git status.

Test plan

• Run node nodes/scripts/gen-node-tables.mjs webhook — git status should show no modifications.
• Run it again — still clean (idempotency check).
• Confirm git check-attr eol -- nodes/src/nodes/webhook/README.md returns eol: lf.

Closes #1329

📝 Walkthrough

Walkthrough

Two files are changed to fix spurious Windows CRLF diffs in generated node README files. .gitattributes adds a rule enforcing LF line endings for all Markdown files. gen-node-tables.mjs normalizes \r\n to \n when reading README content before marker-based injection.

Changes

Windows CRLF Line-Ending Fix

Layer / File(s)	Summary
LF enforcement in .gitattributes and injection script .gitattributes, nodes/scripts/gen-node-tables.mjs	.gitattributes adds *.md text eol=lf to normalize Markdown files to LF; injectBlock() converts \r\n to \n when reading the target README before performing marker replacement.

Poem

🐇 A CRLF snuck in like a weed,
On Windows it caused files to bleed.
Two lines set things right —
LF shines bright!
Now diffs stay clean, guaranteed. ✨
