Flatten the worker module, relocate its tests into a crate-level test module, and delete stale generated artifacts.
- src/worker.rs: flatten the `worker/mod.rs` directory into a single `worker.rs` module file
- src/lib.rs: wire in a new `crate_test` module for crate-level tests
- src/crate_test/mod.rs: move the worker's `tests.rs` into a crate-level `crate_test` module, updating the `Worker` import to `crate::worker`
- deps.dot, deps.html: remove checked-in dependency-graph artifacts
- spectral_report.txt: remove the stale static-analysis report
