fix: CRLF-contaminated git tree entries block Windows checkout

[KooshaPari]

Problem

Every file in the git tree has a trailing \r (carriage return) in its path, e.g.:

".github\r/CODEOWNERS"
".editorconfig\r"
"scripts/federation/f201_*"

The * wildcard filenames in scripts/federation/ also cause Windows path failures.

This blocks git subtree add on Windows hosts and prevents checkout on case-sensitive NTFS.

Root cause

Likely a git add executed inside a CRLF-mode environment where path names were read from a CRLF-terminated file or shell variable, embedding \r into tree entries.

Fix

On a Linux host, run:

git filter-repo --path-rename '\r':'' --force
# Also rename wildcard files
git filter-repo --path-rename 'scripts/federation/f201_*':'scripts/federation/f201_GLOB' ...

Or use git fast-export | sed 's/\r//' | git fast-import.

Impact

Tracked in phenotype-tooling monorepo absorption: PolicyStack is stubbed at crates/policystack/ pending this fix (merge commit 172ab8f).
