chore(deps): bump @cloudflare/sandbox from 0.7.21 to 0.8.4

[dependabot]

Bumps @cloudflare/sandbox from 0.7.21 to 0.8.4.

Release notes

Sourced from @​cloudflare/sandbox's releases.

@​cloudflare/sandbox@​0.8.4

Patch Changes

• #542 eb55c28 Thanks @​dependabot! - Upgrade Go toolchain to 1.25 and update dependencies in the desktop container variant, including a security fix for image processing (CVE-2026-33809).

@​cloudflare/sandbox@​0.8.3

Patch Changes

• #515 bf54f69 Thanks @​Muhammad-Bin-Ali! - Fix slow parallel code context creation. Creating multiple contexts concurrently (e.g. 10 at once) no longer scales linearly with each request — wall time drops from ~5s to ~500ms.

• #493 fdd3efa Thanks @​whoiskatrin! - Add checkChanges() for apps that disconnect and reconnect later but still need to know whether files changed in the meantime.

  Use the returned version in a later call to learn whether a path is unchanged, changed, or needs a full resync. Retained change state lasts for the current container lifetime only.

@​cloudflare/sandbox@​0.8.2

Patch Changes

• #544 9a2f553 Thanks @​whoiskatrin! - Require @cloudflare/containers 0.2.2 or newer so long-running streamed commands stay alive past sleepAfter while work is still in progress.

@​cloudflare/sandbox@​0.8.1

Patch Changes

• #487 19076fb Thanks @​scuffi! - Process termination now walks the command's process tree so killing a process also terminates child processes started by that command

@​cloudflare/sandbox@​0.8.0

Minor Changes

• #519 4103149 Thanks @​scuffi! - Add outbound HTTP interception for sandboxes. Define outbound or outboundByHost handlers on your Sandbox class to intercept, modify, or block HTTP requests made from within the sandbox - with full access to Workers bindings like KV and R2. ContainerProxy is also exported directly from @cloudflare/sandbox. Bumps @cloudflare/containers dependency to 0.2.0+.
