U-009: c_task_create + task lifecycle landing at queued

create_task(): validates goal_text/project_id/task_type (INVALID_PARAM per 03-C §3.1), inserts the task row (status=queued, assigned_org_node=planner, loop_round=0 -- 04-P p_org_task_lifecycle start_state) plus a task_status_changed execution_event, both in one transaction (explicit rollback on failure between the two inserts, tested by dropping execution_event mid-call). c_project_create isn't reimplemented -- it's already complete in U-002 (project_scaffold.create_project). Corrects another Done-line overreach found while scoping this Unit: development-plan.md claimed U-009 alone satisfies all three REQ-01 cases (happy/boundary/failure), but the happy case ("依次触发 planner/coder/ validator...task.status 按状态机正确流转") needs c_org_node_trigger's full implementation -- U-010's own Done criterion is almost that exact sentence, and U-009 doesn't depend on U-010 or even touch org-node triggering. Same class of issue as the U-002/U-036 corrections earlier this session (an SDD/plan line claiming more than the Unit's actual dependencies support), judged low-stakes enough (doesn't change what code to write, just when the REQ-01 happy case gets marked satisfied) to fix directly rather than stop and ask, per the graduated caution this session has been using. Boundary (concurrency limit doesn't block task *creation*, only later scheduling) and failure (INVALID_PARAM) are both fully real at U-009's scope and tested; happy completes cumulatively once U-010 lands. 12 new stdlib unittest cases. 75 total across U-001-009, all passing.

 ### PH1-S1 Org Graph 层单点触发
