Does the file "Dwarf Fortress 0.47.04\Dwarf Fortress.exe" exist, and are you able to launch it manually? If not, my first guess would be that some antivirus software quarantined it. (It's also possible, but unlikely, that it got corrupted somehow, which re-extracting or re-downloading could fix.)

Could you upload your stderr.log file from a run of DFHack that triggered this error? I'm not sure if any additional details will be in it, but they would be more likely to be printed there than to the console.

0.47.04-r4 is up! https://github.com/DFHack/dfhack/releases/tag/0.47.04-r4

Lots of buildingplan and quickfort improvements here, as well as several fixes.

The first one would also warrant a bug report.

As for persistent data: the limitations of the "old" system were due to it saving data in histfigs - specifically, creating histfigs with negative IDs and using fields of their language_name allowed for storing a string name, a string value (both of these limited to around 32k characters), and 7 integers. The underlying storage backend uses JSON now and no longer has these limitations, but the APIs on top of it (including dfhack.persistent and persist-table) haven't changed much yet (the main difference is that the string limitation no longer applies; we could also bump up the number of integers allowed as an intermediate improvement).

You are correct that there is a "pre-save" sort of hook that allows plugins to make any last-minute changes before data is saved (although it could also be used for any custom data-saving logic). The exact logic that triggers it is here: https://github.com/DFHack/dfhack/blob/de21e0cdb86b9002cdcadabd5e8f1dbb68270467/library/Core.cpp#L2008-L2013
Unfortunately, this doesn't appear to be exposed to Lua yet. You could likely catch regular saves with an onStateChange handler, but not autosaves/"quicksave"s. Assuming this would be useful to have in Lua, a GitHub issue would help keep track of this as well.

Explicit targets can be used across documents (strictly speaking, this is a Sphinx feature - the RST spec itself only focuses on single documents).

Same fix seems to have worked - thanks for the report!

I need Catsplosion script analogue that can breed creatures of specie selected by cursor (like for full-heal). For breeding necro's experiments.

You could likely adapt catsplosion fairly easily - this section appears to be the code that creates/shortens pregnancies, and creating a script containing just the highlighted code, as well as the following line before it, should work:
female = dfhack.gui.getSelectedUnit()
Edit: you'll also need to remove the lines referencing variables with "total_" in their names.

A longer-term solution could be to add support for "catsplosion this", similar to "exterminate this" - it would be more complicated than the process I described above, but if that's something that would be useful, we could add support for it.
