refactor(tasks): declare-then-execute — ctx.tasks.start() replaces register()

Browse Source 
start({ kind, label, owner, run }) preflights everything that can fail
(the attachSurface fence, validation, the owner-cleanup attach) BEFORE
invoking the producer's run() starter, then commits atomically —
'work started but never got a collectable id' is now structurally
impossible instead of a producer try/catch rollback obligation (the
P1 review fix, rebuilt on #185's declare/execute split). Producers
lose their catch-wraps; the leak tests now pin the stronger property
that a failed preflight never spawns anything. TaskRegistration splits
into TaskStart (identity + run) and TaskHooks (cancel/done/readOutput);
docs, type-equiv manifest, catalogs, and both RFCs move with it.

# @deepseek-ai/dsh-tool-tasks
The model-facing background task control surface over `ctx.tasks`: three kind-agnostic tools, the completion-notice injection, and the prompt section that teaches the background habit. Loading this plugin calls `ctx.tasks.attachSurface('tool-tasks')`, which is what arms producers' `register()`.
