Writing with /vsizip/ strips metadata, doesn't respect overwrite=TRUE

[Aariq]

Writing to a SOzip by using a /vsizip/ path in writeRaster() only sort of works. The metadata seems to be lost (somewhat defeating the purpose of archiving both the raster and sidecar .aux.json file) and overwrite=TRUE doesn't seem to work. here's a reprex:

library(terra)
#> terra 1.7.78
f <- system.file("ex/elev.tif", package="terra")
r <- rast(f)
units(r) <- "m"
dir.create("test/path", recursive = TRUE)
writeRaster(r,
            "/vsizip/{test/path/out}/out",
            filetype = "GTiff",
            gdal = c("STREAMABLE_OUTPUT=YES", "COMPRESS=NONE"))

units(rast("/vsizip/{test/path/out}/out"))
#> [1] ""

writeRaster(r,
            "/vsizip/{test/path/out}/out",
            filetype = "GTiff",
            gdal = c("STREAMABLE_OUTPUT=YES", "COMPRESS=NONE"),
            overwrite = TRUE)
#> Warning: Deleting /vsizip/{test/path/out}/out failed:
#> Undefined error: 0 (GDAL error 1)
#> Warning: out already exists in ZIP file (GDAL error 1)
#> Error: [writeRaster] failed writing GTiff file

To clarify, it seems the aux.json file both isn't included in the .zip archive and if it was (i.e. the .zip was created with something like zip::zip()), rast("/vsizip/{path/to/zip}/file") doesn't read in the aux.json metadata.
