What this changes

Adds five integration tests for persisted DSH turn endings and removes obsolete dependency pins from the two MSRV jobs. Closes #363.

Why

The tests read DSH's JSONL events for cancellation, failed runs, overlapping runs, session resets and host shutdown, including a late finish while another run owns the turn.

The yoke-derive 0.8.2 pin conflicts with yoke 0.8.4. The derive crate now declares Rust 1.82, allowing Cargo's resolver to select it.

How it was verified

• cargo fmt -- --check
• cargo clippy --all-targets --all-features (CI runs with -Dwarnings)
• cargo test --all-features

On Linux with Node 22.23.4, core build/rustdoc and bridge fmt, Clippy, tests and rustdoc passed (--features node,loader for the bridge).

DSH: 17 passed with YOAGENT_RUTIS_REQUIRE_RUNTIMES=1, one existing univer smoke ignored. Eight faulty variants fail the new assertions, covering wrong reasons, lost error details, missing end events and removal of the owner guard.

Both pin conflicts reproduced on the unchanged base; a derive probe compiled with Rust 1.82. CI passes all 16 jobs on 02370b8, including Rust 1.86/1.88, Linux/macOS/Windows, Wasm, Workers and the Node/Bun/Python/Go fixtures.

Checklist

• Tests cover the change
• CHANGELOG.md updated under ## Unreleased
• Docs updated (docs/ and/or rustdoc) if user-facing (N/A: tests and CI)
• No new public API without a doc comment

Thanks for these tests — they cover every turn ending #363 lists, and the overlap test really pins the owner guard. Reviewed (code + test quality; nothing unsafe, no flakiness found) and adjusted on your branch in 1673edc (a merge commit, so your history is untouched):

• merged main: feat(yoagent-rutis): adapters::files() — the adapter files built in (feature embedded-adapters) #372 had already dropped the yoke-derive pins, so ci.yml takes main's side and the CI CHANGELOG bullet is gone;
• the CHANGELOG entry moved under ## yoagent-rutis Unreleased (it is a yoagent-rutis change), without the blank lines;
• one-line doc comments on the five tests, and their names in integrations/yoagent-rutis/CLAUDE.md.

Locally: dsh_test 17 passed (1 ignored), clippy and fmt clean.

Two optional follow-ups, not blocking: a failed run with no extension named (a provider error, so no (extension …) suffix) and a run stopped after a DSH call ending completed.
