Loki Mode

Added

• Autonomous, complexity-gated decision for the no-PRD codebase-analysis pass.
  When no PRD is provided, Loki reverse-engineers a PRD from the existing code.
  On the Claude provider, when the repo is detected as complex (file_count > 50,
  microservices, external deps, or a complex inferred spec), Loki now dispatches
  that read-only analysis pass as a Claude Code Dynamic Workflow (parallel
  fan-out, the ultracode trigger) for more thorough first-run analysis, and
  otherwise keeps the cheaper three-pass analysis. The decision is made once per
  run (not always-on) and is parity-locked across both routes
  (autonomy/run.sh and loki-ts/src/runner/build_prompt.ts), evaluated in the same
  order: non-Claude provider or degraded provider -> three-pass;
  LOKI_USE_CLAUDE_WORKFLOWS=0 -> three-pass (escape hatch);
  LOKI_USE_CLAUDE_WORKFLOWS=1 -> workflow (force on); variable unset ->
  workflow only when complexity == complex. Simple and standard repos keep the
  byte-identical default behavior. When the workflow path is taken autonomously,
  a one-time stderr disclosure names the higher cost class (no fabricated dollar
  figure; there is no price API) and the LOKI_USE_CLAUDE_WORKFLOWS=0 opt-out.

Fixed

• detect_complexity() was defined but never called on the bash route, so
  DETECTED_COMPLEXITY stayed empty and every complexity consumer
  (effort-for-tier, telemetry, phase selection, and the new analysis gate)
  silently fell back to "standard". It now runs once per run before the first
  prompt build, so the complexity signal is live on bash, matching the Bun route.
• parity-drift CI check: removed an over-normalization that blanked summary
  counts, which was hiding real count drift between the bash and Bun routes.
  The legitimate disk-space and route-specific Runtime normalizations are kept,
  so genuine drift is caught while the prior false positive stays closed.

Docs

• Installation guide now leads with Bun as the recommended install
  (bun install -g loki-mode) with npm as a fully supported alternative,
  matching the README and clarifying that the core autonomous engine runs the
  same on both routes (you lose no capability by choosing Bun).
