[SMOKE TEST] Add a single-line comment to arcane-core's lib.rs

[martinjms]

Add a single-line Rust comment // daemon-smoke-test: ok to crates/arcane-core/src/lib.rs. This is a standalone smoke test — no epic, no branching complexity. Just add the comment line and open a PR targeting main.

Opened PR #94 on branch feat/issue-93-smoke-test-add-a-single-line-comment-to (base: main). Added // daemon-smoke-test: ok to crates/arcane-core/src/lib.rs. Build and tests pass. Formatter clean. Ready for review.

🟢 Work already complete. PR #94 exists with the correct change (// daemon-smoke-test: ok in crates/arcane-core/src/lib.rs). CI is green, PR is non-draft and mergeable.

Nothing to do for this dispatch — the previous run completed the work. Awaiting orchestrator merge.
