The DEPENDS_ON/BLOCKS link types were inert metadata — nothing reasoned about
them. TaskGraph turns them into answerable questions: what a task waits on
(its DEPENDS_ON targets plus any task that BLOCKS it), whether it is ready
(TODO with no unmet blocker — a terminal dependency stops blocking), and what
finishing it would unblock. Readiness surfaces workable tasks to claim; it
never assigns (honouring the rejected /tasks/next scheduler).
Surfaced across the stack:
- TaskService.ready / blockers / blocking.
- Context bundle: a `blocked` flag + `blocked_by` list, rendered as a prominent
"BLOCKED — waiting on ..." line, so an agent calling task_context learns it
should wait before charging at the task.
- GET /tasks?ready=true, GET /tasks/{id}/blockers; correx task ready / blockers.
Cross-project dependencies are scoped to a project for now (documented in
TaskGraph). Tests cover both link directions, terminal-dependency clearing,
the ready filter, the reverse blocking direction, the bundle flag, and REST.
