chore(workspace): promote internal path deps to workspace.dependencies

[AprilNEA]

Summary

• Five workspace members were consumed by other members but path-deped manually instead of going through `[workspace.dependencies]`. As a result `arcbox-net-inject` and `arcbox-fs` were still pinned to `0.4.0` in `arcbox-vmm` while the workspace had moved to `0.4.1`, and future bumps had to be hand-edited per consumer.
• Promote each one so every cross-member dep flows through the workspace, and fix the stale `arcbox-fs` pin while moving it to `workspace = true`.

Crate	Consumer	Notes
`arcbox-route`	`arcbox-helper`
`arcbox-hv`	`arcbox-vmm`	kept on its independent `0.3.20` release line
`arcbox-net-inject`	`arcbox-vmm`	drift fix `0.4.0` → `0.4.1`
`arcbox-migration`	`arcbox-core`
`arcbox-oci`	(none yet)	promoted preemptively for consistency

Also fixes `arcbox-fs` in `arcbox-vmm`: was `{ version = "0.4.0", path = ".." }`, now `{ workspace = true }`.

Test plan

• `cargo check --workspace` clean
• `cargo check --workspace --all-features` clean
• `cargo clippy --workspace --all-targets -- -D warnings` clean
• `cargo fmt --check` clean

Greptile Summary

This PR centralizes five internal cross-member Cargo dependencies into [workspace.dependencies], replacing ad-hoc path-only or stale version + path entries in consumer Cargo.toml files. As a side-effect, arcbox-fs and arcbox-net-inject in arcbox-vmm are corrected from the stale 0.4.0 pin to the current 0.4.1, and all future version bumps only need to be made in the root Cargo.toml.

Confidence Score: 5/5

Safe to merge — pure Cargo manifest refactoring with no logic changes and two correct version-drift fixes.

All changes are mechanical: path-only deps promoted to workspace inheritance, stale 0.4.0 pins corrected to 0.4.1, and arcbox-hv's independent 0.3.20 line preserved correctly in the workspace entry. No code logic is touched, and the PR description's test checklist (cargo check, clippy, fmt) confirms the workspace compiles cleanly. No P0/P1 findings.

No files require special attention.

Important Files Changed

Filename	Overview
Cargo.toml	Adds arcbox-route, arcbox-hv (0.3.20), arcbox-net-inject, arcbox-oci, and arcbox-migration to [workspace.dependencies] with correct versions and paths.
app/arcbox-core/Cargo.toml	Migrates arcbox-migration from path-only dep to workspace = true; no version drift involved.
app/arcbox-helper/Cargo.toml	Migrates arcbox-route from path-only dep to workspace = true; no version drift involved.
virt/arcbox-vmm/Cargo.toml	Migrates arcbox-hv, arcbox-fs, and arcbox-net-inject to workspace = true; fixes stale 0.4.0 pins for arcbox-fs and arcbox-net-inject; arcbox-hv correctly inherits its independent 0.3.20 line.

Pull request overview

Promotes several internal crate dependencies to the workspace-level dependency table so cross-member deps are consistently versioned and don’t drift between consumers (notably fixing stale 0.4.0 pins in arcbox-vmm).

Changes:

• Added missing internal crates to [workspace.dependencies] (arcbox-route, arcbox-hv, arcbox-net-inject, arcbox-oci, arcbox-migration).
• Switched member crates from manual path (and stale version) deps to { workspace = true }.
• Fixed arcbox-vmm’s arcbox-fs / arcbox-net-inject dependency drift (0.4.0 → workspace 0.4.1).
