Remove the unused Tokio io-util feature

This change enables Tokio's io-util feature, but the rewritten filesystem implementation uses std::io::{Read, Write} inside spawn_blocking, and a repository-wide search finds no tokio::io or async I/O extension usage. The fs feature covers create_dir_all and rt covers spawn_blocking, so io-util only expands the enabled dependency surface and should be removed.

Add rationale comments for both cap-std entries and remove the unused io-util feature.

The dependency guidelines require a comment above each newly added dependency entry that explains why the crate is needed and what uses it. Add comments above both cap-std entries.

The workspace uses tokio::fs and tokio::task::spawn_blocking, but it does not use Tokio I/O extension traits. Tokio 1.53.3 does not enable io-util through fs, so remove the direct feature.

Proposed fix

-tokio = { version = "1", features = ["fs", "io-util", "rt"] } +tokio = { version = "1", features = ["fs", "rt"] } +# Capability-based directory handles used by `FsFileStore` to keep artifact +# operations beneath the opened store root. +cap-std = "4"

tokio.workspace = true +# Capability-based directory handles used by `FsFileStore` to keep artifact +# operations beneath the opened store root. cap-std.workspace = true

Add the required rationale for cap-std

The new cap-std workspace dependency is added without the required explanatory comment, even though it supplies the security-critical capability handling for FsFileStore and introduces a substantial platform-specific transitive tree. Add a brief comment immediately above the entry explaining what uses it and why the standard library is insufficient.
