v0.1.2

Changed

• The duho dependency is now >=0.5.0,<0.6. 0.1.1 capped it at <0.4 to
  stay installable; the commands are now declared against duho's current
  argument model instead, so the cap is gone and pkgforge tracks the
  supported duho line again.
• install's source is declared as a list[Path] rather than a
  Union[list[Path], Path]. duho resolves a union by composing its members'
  scalar converters, so a collection member has no way to keep its own
  argparse action and the parser refused to build. The command still accepts
  a bare Path from the Python API; only the annotation narrowed.
• --exclude on install, scan and dbdump is declared with
  duho.Append, making it a repeatable single-value option.

Fixed

• --exclude works through the command line again. It previously combined a
  greedy nargs with an append action, so install --exclude=P produced a
  list of lists (AttributeError: 'list' object has no attribute 'pattern')
  and the bare -X P SRC DST form swallowed the positionals. Both forms now
  parse to a flat statement list; the multi-source regression test drives the
  option through argv rather than assigning it directly.

Notes

• -x/--decompress still takes an optional argument and therefore still
  consumes the following token, so install -x SRC DST reads SRC as the
  compression kind. That is argparse's own behavior for this shape and the
  0.1.1 guard rejecting a path-shaped kind remains in place and necessary.
• The suite also passes against duho 0.4.x, but 0.5 is the series exercised
  and therefore the one declared. CI now runs one job pinned to the declared
  floor so it is verified rather than assumed.
