Adds tasks.decision_id and workplan_dependencies.from_task_id (migration
e8f9a0b1c2d3). A from_task_id column is needed rather than
from_workplan_id plus description: the partial unique indexes key on
(from_workplan_id, target, relationship_type), so two tasks in one
workplan waiting on the same target could not both be indexed, and the
derived wait_kind needs per-task attribution. The two existing unique
indexes are narrowed to frontmatter edges (from_task_id IS NULL) and two
task-origin counterparts are added; downgrade deletes task-origin rows
before restoring the old indexes.
POST /workplans/{id}/dependencies/ accepts from_task_id (must belong to
the from workplan; a task cannot depend on itself). TaskCreate/Update/Read
carry decision_id.
Derived read-model fields, no new write routes (rule 5):
- TaskRead.wait_kind: external | human | both | unqualified, null unless
status is wait (dependency rows from this task / needs_human).
- WorkplanRead.blocked_kind: human | external | none, null unless status
is blocked. Human wins over external.
Both come from api/services/wait_kind.py, applied on GET /tasks/,
GET /tasks/{id}, GET /workplans/ and GET /workplans/{id}.
The identifier-migration reference-count proof now includes from_task_id
(FK count guard 22 -> 23).
