AkurAI-Build

Latest change 1488f88860de09bbb6791f4c67d3a8a8a3e0765f - Replace the JSON CI CLI with a full read/write akurai-build MCP tool set (repo add/host/sync/rename/remove/visibility/branches/tree, run queue/wait/retry/promote, artifact get, doctor, init); keep keygen/migrate/serve as plain CLI subcommands; update skill and deploy.md to the MCP tool set by Ólafur Búi Ólafsson
