Get a task's dependencies
Both directions of the task's blocker graph one hop out: `blocked_by` (must finish first) and `blocking` (waiting on this task), plus the derived `is_blocked`. A task with no links answers an empty view rather than 404. This is not paginated — the answer is a task's immediate neighbours, not a traversal; walk the chain by following each `task_id`.

Fetches a single project by id, scoped to the credential's organization. A project id from another organization (or an unknown id) answers 404 `resource_not_found` — no cross-org existence oracle.
Record a blocker POST
Records that the task in the path is blocked by `blocker_task_id` — the SAME operation the MCP `link_task_dependency` tool executes. Recording a link that already exists succeeds unchanged (no duplicate row, no second webhook), so retries are safe. A link that would close a loop is REFUSED with 409 `dependency_cycle`: the graph a client reads is guaranteed acyclic. A task cannot block itself (400 `validation_failed`), and a blocker in another organization is indistinguishable from one that does not exist (404 `resource_not_found`). Answers the task's full dependency view, so the caller can see whether it is now blocked without a second call.
