Errors when running `cargo nested check` with `build-wrap`

[smoelius]

Recently, I started seeing the following from cargo nested check:

error: failed to run custom build command for `dylint_examples v5.0.0 (.../gh/trailofbits/dylint2/examples)`

Caused by:

According to Claude, the attempt to write a readonly database is the error, and everything before that is just noise.

Also, Claude says this is likely tied to recent build directory layout changes.
