Working-tree upload refuses linked worktrees and scratch-space checkouts

You'll notice

Working-tree upload now refuses linked worktrees and checkouts sitting in temporary scratch directories.

What

Two new refusals stop an upload before it starts. linked_worktree covers a checkout whose worktree pointer files could not be verified, one using per-worktree git config, or one in an untrusted location. temp_root covers a checkout, or a symlink on the way to it, that lives under a temporary directory cloud sessions use as scratch space.

Details
  • Scratch roots are computed from CLAUDE_CODE_TMPDIR, TMPDIR, TMP and TEMP.
  • Per-worktree config is detected via the git setting extensions.worktreeConfig.
  • Settings-file identity is re-checked across CLAUDE_CONFIG_DIR, HOME, USERPROFILE and related variables.
  • The older fallback path gained a matching linked_worktree message.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
