fix: fix go to source file whose path contains $ symbol

[knthmn]

🎯 Changes

Fix @tanstack/devtools-vite click-to-code for source files whose paths contain $. The previous implementation escaped $ before passing the path to launch-editor which turns a real path e.g. src/routes/$postId.tsx into src/routes/\$postId.tsx. launch-editor checks fs.existsSync(fileName) before spawning the editor, so the escaped path fails existence checks.

Verified locally by:

• building @tanstack/devtools-vite
• linking the local package into an app with TanStack router
• confirming click-to-code now opens $... route files correctly in both VS Code and IntelliJ

I am not sure why this wasn't reported before since TanStack Router makes heavy use of $ in file path. I believe my fix is independent of OS and editor, please point out if the fix is wrong.

📝 Walkthrough

Walkthrough

The PR stops escaping $ in the file path when building the filename:line:column argument passed to launch-editor and updates the changelog entry to publish a patch noting the go-to-source fix for $-containing paths.

Changes

Editor path argument handling

Layer / File(s)	Summary
Remove dollar sign escaping from path argument packages/devtools-vite/src/editor.ts	The launch-editor path argument in DEFAULT_EDITOR_CONFIG.open no longer escapes dollar signs and uses the raw path when constructing the filename:line:column argument.
Patch changeset update .changeset/floppy-mammals-write.md	Changeset updated to publish a patch for @tanstack/devtools-vite and documents the fix for go-to-source when file paths contain $.

🐰 A dollar sign hops through the code,
Unescaped it finds a friendly road,
One tiny change, a cleaner flight,
Source opens true, just right tonight,
