feat: add task_local! macro and LocalKey for task-scoped storage

Adapted from tokio task::LocalKey (v1.44, MIT) to provide
runtime-agnostic task-local storage. This decouples task-local
functionality from tokio, enabling use with any AsyncRuntime
implementation (monoio, compio, etc.). The task_local! macro
declares statics backed by thread-locals, with scope() /
sync_scope() swapping values in and out per logical task.

Changes:
- Add pin-project-lite dependency for TaskLocalFuture projection
- Add task_local! and __task_local_inner! macros at crate root
- Add LocalKey with scope, sync_scope, with, try_with,
  get, try_get methods
- Add TaskLocalFuture with PinnedDrop that preserves task-local
  access during future cleanup
- Add 5 task_local tests to Suite<Rt> in testing.rs
