Shorten dependency registration critical sections without increasing allocations. Keep small dependency maps inline, avoid redundant completion locks, and reuse notification buffers while preserving graph and queue semantics. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Dependency registration currently allocates collection storage and repeats completion locking while holding the context-wide lock, extending waits for unrelated tasks. Shorten this critical section without weakening synchronization or increasing allocations. Preserve reference counting, key equality, pending-work accounting, and queue-draining behavior, with notifications still pulsed outside the lock.
