Build fails on Windows: inject-tool-templates.js cannot find end marker

[rattusrattus]

Description

The npm run build command fails on Windows during the build:templates step with:

❌ Could not find tool content container markers

Root Cause

The build/inject-tool-templates.js script uses a hardcoded Unix-style line ending pattern (\n) to find the end marker in index.template.html. On Windows, files may have CRLF (\r\n) line endings, causing the pattern match to fail.

Environment

• OS: Windows 10/11
• Shell: Git Bash / PowerShell / CMD
• Node.js: v20+

Steps to Reproduce

1. Clone the repo on Windows
2. Run npm install
3. Run npm run build
4. Build fails at build:templates step

Suggested Fix

Add fallback pattern matching for Windows line endings while preserving the original Unix behavior. I've prepared a PR with a backwards-compatible fix.

Workaround

Users can manually convert index.template.html to Unix line endings using:

dos2unix index.template.html

But a proper fix in the build script would be preferable for cross-platform compatibility.

[tcpelana]

Open the file build/inject-tool-templates.js and apply this snipper change:

• Find Line 49 (where the Unix-style line endings (\n) are read), it should look like:
  let indexContent = fs.readFileSync(templatePath, 'utf8');

• INSERT this line just below:
  indexContent = indexContent.replace(/\r\n/g, '\n');

What it does?
It converts all "dirty" Windows-style line endings (\r\n) to clean Unix-style line endings (\n) in memory, before the script searches for markers. This ensures the exact match on line 53 will always work—regardless of your operating system.
