feat(shell): job-aware kill, disown, jobs/set flags, fallback REPL history

- Document interactive shell vs /bin/sh in bare-os-shell man, handbook §9,
  kill(1), and shell-completion guide
- Resolve kill %n and %% to synthetic PIDs via shellBackgroundJobs
- Add disown builtin; jobs -p (pgid-only) and -l (pid column); set -o/+o to
  print errexit/nounset/pipefail/noglob
- Expand completion-engine fallback flags for common utilities
- Persist lines to /.bare/repl_history_<USER> when BARE_OS_REPL_HISTORY=1
  and Fish REPL is off (repl-session + cli-readline)
- Tests: kill job specs, set -o output, jobs -p
