Implement Unwrap on breakoutErr so callers can inspect the underlying filesystem error with errors.Is and errors.As.

Embedding error preserves its Error method, but does not automatically add the wrapped error to the standard error chain.

build(deps): bump the go-modules group in /e2e-go with 2 updates [ski…
797b663 
…p ci]

Bumps the go-modules group in /e2e-go with 2 updates: [github.com/moby/go-archive](https://github.com/moby/go-archive) and [github.com/shirou/gopsutil/v4](https://github.com/shirou/gopsutil).
Updates `github.com/moby/go-archive` from 0.2.1 to 0.3.2
Release notes

*Sourced from [github.com/moby/go-archive's releases](https://github.com/moby/go-archive/releases).*

> v0.3.2
> ------
>
> What's Changed
> --------------
>
> Fix a regression introduced in v0.3.0 that caused archive extraction to fail when paths traversed absolute symlinks inside the destination root, such as `var/run -> /run`. Absolute symlink targets are now resolved relative to the extraction root while relative symlink escapes remain rejected. [moby/go-archive#93](https://redirect.github.com/moby/go-archive/pull/93)
>
> **Full Changelog**: <moby/go-archive@v0.3.1...v0.3.2>
>
> v0.3.1
> ------
>
> Fixes
> -----
>
> This patch release fixes a regression introduced in v0.2.1 where archive extraction could fail when an archive omitted explicit entries for parent directories. For example, extracting `etc/dnf/` without a preceding `etc/` entry could return `mkdirat etc/dnf: no such file or directory`.
>
> This prevented affected images from being extracted. Archive extraction now creates implied parent directories for both file and directory entries.
>
> What's Changed
> --------------
>
> * archive: create implied parents for directory entries [moby/go-archive#92](https://redirect.github.com/moby/go-archive/pull/92)
> * archive: Tarballer.Go: suppress io.ErrClosedPipe logs on close [moby/go-archive#94](https://redirect.github.com/moby/go-archive/pull/94)

> **Full Changelog**: <moby/go-archive@v0.3.0...v0.3.1>

> Security
> --------
>
> This release fixes **CVE-2026-17106** / **[GHSA-hfg8-hc9c-6c3h](https://github.com/moby/go-archive/security/advisories/GHSA-hfg8-hc9c-6c3h)**, where a crafted tar archive could use links to cause extraction operations to create or overwrite files outside the intended destination directory.
>
> The issue affected `Unpack`, `UnpackLayer`, `Untar`, `UntarUncompressed`, and the `ApplyLayer` helpers. Users should upgrade and avoid extracting untrusted archives with earlier versions.
>
> What's Changed
> --------------
>
> * archive: harden tar extraction against path traversal [moby/go-archive#45](https://redirect.github.com/moby/go-archive/pull/45)
> * archive: do not follow reparse points in chtimes [moby/go-archive#90](https://redirect.github.com/moby/go-archive/pull/90)
> * archive: fix creation time updates on Windows [moby/go-archive#79](https://redirect.github.com/moby/go-archive/pull/79)
> * archive: minor cleanups and godoc touch-up [moby/go-archive#87](https://redirect.github.com/moby/go-archive/pull/87)
