0.2.0

Breaking changes

• LAPT_OPT_ROOT/LAPT_CACHE_ROOT are gone — everything lapt owns now
  lives under a single, fixed $LAPT_HOME ($HOME/.lapt). Run lapt init
  and source the printed env.sh to pick up installed packages' binaries
  and man pages again (re-sourcing it, e.g. in a nested shell, is now safe
  and won't duplicate PATH/MANPATH entries).
• Exposure now covers bin/ and man pages only — bash-completion,
  .desktop files, icons, and MIME data are no longer exposed at all
  (previously written under $HOME/.local).

Changed

• lapt vendor is now a thin layer over lapt install: it requires the
  named packages already be installed, then just prints an env script
  (PATH, LD_LIBRARY_PATH, PKG_CONFIG_PATH) pointing at their
  opt/<pkg> trees — no separate fetch/closure/bundle step, no files
  written anywhere.
• lapt install no longer aborts on library-only packages (e.g.
  libevent-dev, which has no usr/bin of its own).

Added

• lapt install/lapt remove accept multiple packages; failures are
  collected and reported together without stopping the rest from
  installing/removing.
• lapt list [pkg...] accepts optional names to filter to, instead of
  always listing everything.
