Loki Mode v7.13.0

Added

• Auto-wiki + cited codebase Q&A (R5 of the competitive arc): Loki's answer to
  a per-repo knowledge base. loki wiki generate | show | ask builds a
  persistent per-project wiki (architecture overview, key modules, data flow)
  from the codebase under .loki/wiki/, and loki wiki ask "<question>"
  returns an answer grounded in the actual code with file:line citations.
• Citation integrity is structural, not best-effort: the model is shown numbered
  code chunks and cites by index only; each citation is mapped back to the real
  chunk's file:line and validated against disk before it is surfaced. A
  fabricated or non-resolving citation cannot survive (it is dropped). Generate
  citations are derived from the code scanner (real def/class line numbers).
• Dashboard wiki browser panel (Overview / Architecture / Key Modules / Data
  Flow / Ask tabs) and wiki API routes, so the wiki is a browsable, shareable
  team artifact. The .loki/wiki/ directory (wiki.json + per-section markdown)
  is portable and readable without the dashboard.
• Incremental regeneration: the wiki is keyed by a codebase signature (git HEAD
  • per-file content hash); loki wiki generate skips when the codebase is
    unchanged, with --force to override.

Notes

• No duplication: token-overlap retrieval reuses the scoring pattern from
  memory/knowledge_graph.py; the wiki index is intentionally dependency-free and
  CI-safe (distinct from the optional ChromaDB code index). bash and Bun routes
  delegate to one shared Python core (generate/ask) for parity.
• Council: 3-of-3 unanimous (round 2, after a one-line TypeScript test-typing
  fix). LLM calls are stubbed in tests (zero paid API calls in CI).
• NOT tested in this release: wiki quality on a very large (>1M LOC) codebase;
  semantic questions whose terms do not appear literally in the code (token-
  overlap retrieval, with ChromaDB noted as a future optional backend).
