specified as a JSON object passed via stdin to qgis_process
This provides a mechanism to support complex input parameters
for algorithms, and a way for qgis_process to gain support
for parameter types which are themselves specified as a dictionary
type object.
To indicate that parameters will be specified via stdin then
the qgis_process command must follow the format
qgis_process run algid -
(with a trailing - in place of the usual arguments list).
The JSON object must contain an "inputs" key, which is a map
of the input parameter values.
E.g.
echo "{"inputs": {\"INPUT\": \"my_shape.shp\", DISTANCE: 5}}" | qgis_process run native:buffer -
Specifying input parameters via stdin implies automatically
the --json output format for results.
One big motivation behind this enhancement is to provide a way for
the qgisprocess R libraries to support parameter types such as
aggregates.

Long story short, the `layer.committedFeaturesAdded` signal is not fired after `layer.commitChanges()` when in transaction mode.
If the layer is using the `QgsVectorLayerEditBuffer` the `commitedFeaturesAdded` signal is fired.
But if transaction is used and the `layer.editBuffer()` returns `QgsVectorLayerEditPasstrough`, then there is no signal.
The `QgsVectorLayerEditPasstrough` class is quite empty and lacking implementation of these events, so they don't work on layers in a transaction group.
Also, make sure that non enforced constraints
do not block commits and do not report as violated
constraints (Fix#46364).
Followup #46439 because the constraints were
not checked agains the widget value but against
the attribute value.

Specifically, this method should be used to determine the
most-permissive possible resultant WKB type which can result
from subtracting parts of a geometry. A single-point geometry
type can never become a multi-point geometry type as
a result of a subtraction, but a single-line or single-polygon
geometry CAN become a multipart geometry as a result of subtracting
portions of the geometry.
