chore: migrate to workspace-level dependency declarations (vllm-project#43)

## Summary

- Adds `[workspace.dependencies]` to root `Cargo.toml` and switches all
three crates to `dep.workspace = true`
- This is the non-reverted portion of vllm-project#35 — dependency centralisation
only, no module moves
- No behavioral changes; all code stays where it is

## Test plan

- [x] `cargo build` — clean
- [x] `cargo test` — all pass
- [x] `cargo clippy --all-targets -- -D warnings` — clean
- [x] `cargo fmt -- --check` — clean
- [x] `pre-commit run --all-files` — all hooks pass
