rTime now pulls tasks from rTasks boards instead of maintaining its own
Task type. New WeavingDoc stores canvas overlay data (needs, position,
notes, links) while rTasks BoardDoc remains source of truth for task
metadata. 6 new /api/weave routes, updated connections/exec-state to
WeavingDoc, compat shims on legacy endpoints, task picker for unplaced
rTasks items, MCP tools updated (rtime_list_woven_tasks, rtime_place_task),
migration script for existing data.
