fix(message_bus): expose background_tasks_len in release builds (#3242)
The accessor was gated by `#[cfg(any(test, debug_assertions))]`,
which hid it from the `installer_panic_cleanup` integration test
in release builds: integration tests live in a separate crate, so
the library's `cfg(test)` is unset, and `debug_assertions` is off
under `--release`. Both predicates failed only in the release ×
integration-test quadrant, which CI does not exercise.
Drop the cfg and mark `#[doc(hidden)]`. The accessor is a zero-cost
getter over a `RefCell<Vec<_>>` and carries no prod risk; doc-hidden
preserves the "test-only invariant probe" signal without breaking
external test crates.
Fixes #3234
