feat(install): adopt the statusline script into the managed set

An archsetup session added a statusLine entry to the tracked settings.json on 2026-06-11 (Craig's request), pointing at ~/.claude/statusline-command.sh, but the script itself lived outside the repo on one machine. This commits the settings entry and brings the script into .claude/, linked by make install like the rest of the config, so it reaches every machine on the next session.

Two fixes over the original: uname -n instead of hostname (Arch doesn't ship hostname by default, so the host rendered empty with stderr noise), and the tilde replacement is escaped (unquoted, bash expands the replacement ~ straight back to $HOME, which defeated the abbreviation). scripts/tests/statusline-command.bats covers the format, branch handling, and the no-stderr contract.
