feat(core): three-layer DAG, unified component arch, commands-registry cache, Nushell 0.112.2 migration - DAG architecture: `dag show/validate/export` (nulib/main_provisioning/dag.nu), config loader (lib_provisioning/config/loader/dag.nu), taskserv dag-executor. Backed by schemas/lib/dag/*.ncl; orchestrator emits NATS events via WorkspaceComposition::into_workflow. See ADR-020, ADR-021. - Unified Component Architecture: components/mod.nu, main_provisioning/ {components,workflow,extensions,ontoref-queries}.nu. Full workflow engine with topological sort and NATS subject emission. Blocks A-H complete (libre-daoshi). - Commands-registry: nulib/commands-registry.ncl (Nickel source, 314 lines) + JSON cache at ~/.cache/provisioning/commands-registry.json rebuilt on source change. cli/provisioning fast-path alias expansion avoids cold Nu startup. ADDING_COMMANDS.md documents new-command workflow. - Platform service manager: service-manager.nu (+573), startup.nu (+611), service-check.nu (+255); autostart/bootstrap/health/target refactored. - Nushell 0.112.2 migration: removed all try/catch and bash redirections; external commands prefixed with ^; type signatures enforced. Driven by scripts/refactor-try-catch{,-simplified}.nu. - TTY stack: removed shlib/*-tty.sh; replaced by cli/tty-dispatch.sh, tty-filter.sh, tty-commands.conf. - New domain modules: images/ (golden image lifecycle), workspace/{state,sync}.nu, main_provisioning/{bootstrap,cluster-deploy,fip,state}.nu, commands/{state, build,integrations/auth,utilities/alias}.nu, platform.nu expanded (+874). - Config loader overhaul: loader/core.nu slimmed (-759), cache/core.nu refactored (-454), removed legacy loaders/file_loader.nu (-330). - Thirteen new provisioning-<domain>.nu top-level modules for bash dispatcher. - Tests: test_workspace_state.nu (+351); updates to test_oci_registry, test_services. - README + CHANGELOG updated.
