Loki Mode

Added

• Claude Code Dynamic Workflows adoption, opt-in and Claude-provider-only
  (issue: workflows-embed). Two surfaces, both additive; the council, the 11
  quality gates, the evidence gate, and the RARV loop are untouched (they stay
  hand-rolled, deterministic, and provider-agnostic by design).
  • loki ultracode "<task>": a passthrough that prepends the ultracode
    keyword so a native Claude Code Dynamic Workflow (background multi-agent
    fan-out) runs for the task. Loki adds no orchestration of its own. Opt-in
    (explicit command), capability-gated (Claude provider AND claude CLI

    = 2.1.154 AND workflows not disabled), with a cost-class disclosure printed
    every time (workflows spawn many agents and cost meaningfully more; no dollar
    figure is shown because there is no price API). Non-interactive without
    --yes refuses with exit 2 and zero invocation. On Codex/Cline/Aider or an
    older/disabled CLI it prints an honest message and exits cleanly.

  • LOKI_USE_CLAUDE_WORKFLOWS=1 (default OFF): when set on the Claude provider,
    the first-run READ-ONLY codebase-analysis pass (the no-PRD reverse-engineer
    step) is dispatched as a workflow fan-out. Default behavior is byte-identical
    when the flag is off or the provider is not Claude (deterministic fallback to
    the existing three-pass analysis). Read-only; never gates "done".
