download.pause/resume/start/cancel and queue.start/stop were stubs; now they call into the scheduler and take effect immediately, not on the next 1s tick — pausing, resuming or cancelling a live transfer can't wait, and per ADR 0013 §3 the governor never touches a user-owned pause on its own. New rpc::TaskActionPort interface (owned by rpc/, implemented by sched::Scheduler) is what dispatcher.hpp depends on instead of sched/scheduler.hpp directly. Needed because veloxd_sched already links veloxd_rpc (for EventHub); dispatcher.hpp pulling in sched/scheduler.hpp directly would make it a real circular library dependency, breaking anything that links veloxd_rpc alone (cli's tests, as it turned out — hit and fixed during this change). Scheduler::user_pause/user_resume/user_start/user_cancel + pause_queue follow tick()'s existing to_pause pattern: call the engine (async, no synchronous effect) and transition the store eagerly so download.get/list are correct the instant the RPC call returns. Fixed a real bug surfaced while building this: transition() always overwrote pause_reason to NULL when the engine's own delayed pause-ack callback (on_state to paused, no error) arrived after whoever actually initiated the pause had already written the real reason — now it preserves the stored reason when the callback supplies none, instead of clobbering it. Covered by a regression check in sched_scheduler_test. store/queues gets get() and set_state() (was list()-only) for queue.start/stop. Verified against real veloxd + tools/testserver, not just unit tests: pausing a live single-segment throttled transfer freezes downloadedBytes, resume continues it from that point, cancel stops it; a bad taskId comes back in BulkTaskResult.failed with -32010, not a crash; queue.stop(pauseRunning:true) pauses the queue's running task immediately and queue.start resumes admission. Known gap: download.start's contract "a task in 'queued' jumps its queue" (priority bump) is not implemented — admission is still plain FIFO by created_at. Noted in deferrals.md.
