Closes #550 (all four): - Cancellation: track live subprocesses; POST /ansible/runs/<id>/cancel (operator) SIGTERMs then SIGKILLs after a grace; new 'cancelled' status (+ migration 0019, ALTER TYPE in autocommit). Queued runs cancel cleanly before launch. Cancel button on run detail. - Concurrency: global semaphore (ansible.max_concurrent_runs, default 3, Settings→Ansible) caps simultaneous runs; excess show 'queued' (new status) until a slot frees. Semaphore bound lazily per running loop. - Structured results: parse PLAY RECAP into per-host ok/changed/unreachable/ failed/skipped + capture failed-task lines, stored in new results JSON column (migration 0020); rendered as a host-summary table on run detail. Keeps live streaming (no json-callback swap). - Retention: full output written to a persistent log artifact (/data/ansible/runs/<id>.log, env-overridable) beyond the 1 MB DB cap and across restarts; in-memory replay buffer bounded + GC'd after completion; Download-log route. Boot reconciliation now also sweeps stale 'queued'. Unit tests for recap parsing + cancel flagging. Status colors updated across run list / detail / schedules.
