Invalid file paths break Windows checkout (colons in filenames)

[rocket71]

Problem
Checking out on Windows fails due to files with colons in their paths, which Windows doesn't support:

git checkout error: invalid path 'Releases/v2.3/.claude/skills/Browser/Tools/https:/danielmiessler.com/blog/introducing-amazon-curate-i-wish' error: invalid path 'Releases/v2.3/.claude/skills/Browser/http:/localhost:5173/ideas' error: invalid path 'Releases/v2.3/.claude/skills/Browser/http:/localhost:5173/ideas#the-full-archive'

Cause
It looks like the Browser skill is saving URLs as literal filenames. Windows prohibits : in file paths (reserved for drive letters), so these files can't be created or checked out.
Suggested Fix

Remove the invalid files from the repo
Update the Browser skill to sanitize URLs before using them as filenames (e.g., URL-encode or hash them)

Environment

Windows 11
Git 2.x
Cloned with --filter=blob:none (blobless clone)
