CAS-13318 : Fix PB masking in robust RMS calc
The initial bug seems to be because the outlierfield lies outside the
specified PB mask, and ends up being all masked pixels. This causes the
RMS estimation to fail, as well as deconvolution.

The fix is to switch the default mask to be unmasked in an outlierfield,
and after the PB mask is applied if the image is completely masked,
temporarily unmask it for RMS estimation.

This fixes the initial issue reported in the ticket, but investigating
if there are any unintended effects.

PIPE-3061: add pixi tasks for regression/unit tests and developer docs
Add two pixi tasks to pyproject.toml:
- test-regression: runs tests/regression/fast/ with pytest-xdist
  (worksteal, -m "not mpi") inside a plain Python session
- test-pltest1: runs a single small ALMA-IF regression test via `casashell`

Both tasks cd into PL_WORKDIR (default: ../working) before launching,
keeping CASA logs and pipeline output out of the source tree.
PL_WORKDIR is overridable at invocation time:
  PL_WORKDIR=/zfs/scratch/myrun pixi run test-regression

Also add docs/source/develdocmd/pixi_tasks.md documenting all five
pixi tasks (test-unit, test-regression, test-pltest1,
fetch-casarundata, build-docs), the available CASA environments,
PL_WORKDIR usage, and per-environment invocation examples.

PIPE-3027: add `@pytest.mark.mpi` marker and `--ignore-mpi-markers` option
- Add `mpi` pytest marker to `pyproject.toml`
- Auto-skip `@pytest.mark.mpi` tests in pytest_collection_modifyitems
  when `MPIEnvironment.is_mpi_enabled` is False
- Add `--ignore-mpi-markers` CLI flag to disable the auto-skip, allowing
  mpi-marked tests to run in a serial session
- Apply `@pytest.mark.mpi` to tests that require an MPI-enabled CASA
  session: two alma_if fast tests and one vla fast test
