fix(rs): make internal dev-dependencies path-only so releases publish

[kixelated]

Release RS for #3945 failed, so moq-ffi 0.4.1 and the rest of the release never reached crates.io:

failed to publish hang: failed to select a version for the requirement moq-tokio = "^0.19.12"

hang depends on moq-tokio only as a dev-dependency, via workspace = true, which carries the workspace version. cargo publish keeps a versioned dev-dependency and requires it to exist on crates.io. release-plz orders publishes by normal dependencies only, so it published hang before moq-tokio 0.19.12 existed. hang's moq-mux dev-dependency already used a plain path, which cargo strips on publish.

• Manifests: every internal dev-dependency of a published crate is now path-only. That's 11 crates: hang, libmoq, moq-cli, moq-hls, moq-relay, moq-room, moq-rtc, moq-rtmp, moq-srt, moq-transcode, moq-uring. The moq-tokio ones keep the workspace's default-features = false, so the feature set doesn't change.
• Guard: just rs _publish-test, already in just check, now fails on a versioned internal dev-dependency. It fails on the old hang manifest and passes now.
• Verified: cargo package -p hang --no-verify (the step that failed) now succeeds, and just check passes.

This is an exception to the rs/CLAUDE.md line "crates reference deps via { workspace = true }". I left that file alone. A possible rewording: "...via { workspace = true }, except internal dev-dependencies, which are path-only (enforced by _publish-test)."

When this merges, Release RS publishes the pending versions, moq-ffi 0.4.1 included.

Public API / wire impact: none. Published manifests drop these dev-dependencies, which don't affect consumers.

MERGE

Positive improvement: yes. Release RS for #3945 failed because hang's moq-tokio dev-dependency came through workspace = true (so ^0.19.12), and cargo publish still requires that version on crates.io. release-plz only orders by normal deps, so hang published before moq-tokio 0.19.12 existed. Switching internal dev-deps to path-only matches what moq-mux already did in hang, and cargo strips those on publish. The _publish-test guard is the right place to keep this from regressing.

Worth the complexity: yes. Eleven one-line Cargo.toml edits plus a small jq check in an existing private recipe. No public API or wire impact. Feature sets look preserved: the workspace already pins moq-tokio with default-features = false, and the path forms restate that where features are listed.

Different approach: teaching release-plz to order on versioned dev-deps would be upstream and fragile; keeping versioned workspace dev-deps and hand-ordering publishes is worse. Path-only for internal test-only deps is the cargo-idiomatic fix. Optional follow-up (not a merge blocker): reword the rs/CLAUDE.md workspace-deps line as the PR description suggests so the exception is documented next to the rule.

Walkthrough

Several crates now reference internal dev-dependencies by local path instead of workspace dependency. The _publish-test check scans published packages and rejects path-based dev-dependencies with version requirements other than *.

Priority: ➖ Normal

Merge Risk: 🔵 Low · up to 56e25

The current release is not blocked by this gap. The publish check should also catch version-only internal dev-dependencies before one is added.
