v2.7.1 — Hook installer works from a git worktree

Fixed

• Installing from inside a git worktree aborted half-way. git-hooks/install.sh copied hooks to
  <toplevel>/.git/hooks/, but in a linked worktree .git is a file, so cp failed with "Not a
  directory" and set -e stopped the whole devkit install at step 3/5. Hooks now go to the repo's
  common git dir (git rev-parse --git-common-dir), which every worktree shares, and the success
  message prints where they actually landed.
