[PATCH v6 0/3] rust: workqueue: add safe cancellation and status methods

[Aakash Bollineni via B4 Relay <devnull+aakash.bollineni.multicorewareinc.com@kernel.org>]

Changes in v6:
- Refactored rust_helper_init_delayed_work to ensure robust, single-pass initialization 
  using standard kernel macros, avoiding redundant lockdep and timer setup.
- Simplified impl_has_delayed_work! macro by using direct pointer casting for 
  work_container_of.
- Added missing # Safety documentation blocks to reclaim methods for Arc and KBox.
- Improved documentation readability by adding vertical whitespace to all examples.
- Cleaned up link syntax by using direct inline links and removing redundant reference lists.
- Removed unused rust_helper_get_dwork_timer_fn C helper.
- Link to v5: https://lore.kernel.org/r/20260407-workqueue-v5-sent-v1-0-d0d635289ca0@multicorewareinc.com

PLEASE IGNORE v4. This version (v5) corrects a critical KUnit build error 
and formatting regressions that were present in the previous submission.

Changes in v5:
- Fixed missing arc_count helper in rust/kernel/workqueue.rs that caused KUnit
  build failures.
- Fixed formatting in samples/rust/rust_workqueue_test.rs via rustfmt.

Changes in v4:
- Fixed Reported-by/Closes tags and metadata for robot tracking.
- Improved commit structure to separate API changes from tests.
