tasks/ — background task capability family

The shared home for background-task ids, owner isolation, reads, cancellation, waiting, and completion notices. Bash, subagents, and future long-running tools use one model-facing protocol. See the background-task runtime Agent Note.

Package	ctx key	Role
tasks (@deepseek-ai/dsh-tasks)	ctx.tasks	The registry service: branded <kind>-N ids, owner-fenced read/kill/wait/list, settlement bookkeeping, the awaited owner-cleanup path, and the attachSurface misconfiguration fence
tool-tasks (@deepseek-ai/dsh-tool-tasks)	—	The model-facing control surface: task_output, task_list, task_kill, the completion-notice injection, and the background-habit prompt section

The registry owns state across producer or surface reloads; the tool package owns presentation. Producers register execution hooks through ctx.tasks.start and own whether their config exposes run_in_background.
