An environment overlay that points a test process at a *private, writable* depot layered
on top of that Julia's own default depots.

The private depot lives in a stable directory under the system temp dir, never in the
user's own depot: these are test artifacts, and `~/.julia` is not ours to leave things in.
Stable rather than an `mktempdir()` because the precompile caches it accumulates are worth
keeping between runs — a fresh depot per run means recompiling `BasicPackage`'s
dependencies from scratch under every Julia version the platform items cover. Point
`TIC_TEST_DEPOT_ROOT` somewhere else to override the location.

Per-version test items run concurrently, and every worker run reaches Pkg (`Pkg.develop`
on Julia <= 1.10, `Pkg.instantiate` inside TestEnv), which rewrites depot-wide usage logs
such as `logs/manifest_usage.toml` without locking on older Pkg versions. Making the
