The .git-only walk left the working tree root-owned, so agents (uid 1000)
could not write any file — every mkdir/open/commit failed with EACCES and the
run died. Walk the whole workspace, chowning the root + tracked files + .git,
while pruning the heavy gitignored trees (node_modules/.venv/dist/...) that
made the full walk slow. Verified on the host: uid-1000 write succeeds after.
