fix(scheduled-tasks): seed task contexts instead of clobbering auto-mentions

Cursor (Medium): the mount-only `setContexts(task.contexts)` replaced the
editor's context list AFTER the chipify pass had already registered the
prompt's integration `@`-mentions and `/`-skills, so a task with any stored
resource context lost its integration/skill chip overlay.

Thread an `initialContexts` option through `usePromptEditor` (into the
context manager's existing `initialContexts` seed) and seed the task's
stored contexts there. The mount chipify pass then MERGES integration and
skill contexts on top of the seed (deduped), so the overlay renders the
full set — resources from the seed, integrations/skills from the text.
