PR 13538 checkpoint long-path verification
Linux x86_64, Node v24.21.0
Base: 1451e7cb23034d29774338608368a15d8845df36
Tested head: 3e1f62c37079aea1efa1b919ef4601c094d1e539

BEFORE: base production with revised regression tests
Command (apps/server): TMPDIR=/tmp/desktop-app-04 ../../node_modules/.bin/vp test run src/vcs/GitVcsDriver.test.ts -t "checkpoint working-tree commands enable Git long paths"
note: You are running `vp test` as a Vite+ built-in command. If you meant to run the test npm script, use `vpr test` instead.
