ClaudioDrews 1422a6d583 fix: resolve 5 easy Phase 4 performance/resilience issues 
V4.04: Add retry_transient() to dlq_manager — re-enables reported transient
  failures for retry with --retry CLI flag, increments retry_count/last_retry

V4.05: save_report() now truncates JSONL to MAX_REPORT_HISTORY entries
  after each append (best-effort rotation)

V4.06: Wrap datetime.fromisoformat() in try/except (ValueError, TypeError)
  in get_status_summary() — skips entries with malformed timestamps

V4.08: Replace body[:50] dedup key with hashlib.sha256(body).hexdigest()
  in fabric-retrieve.py deduplicate()

V4.09: Add OrderedDict LRU cache (256 entries) to embedding.py get_embedding()
  — avoids recomputing embeddings for repeated text

ClaudioDrews ff781f9824 feat: add EMBEDDING_API_KEY for authenticated non-OpenRouter endpoints (fixes #8) 
embedding.py:
- Add EMBEDDING_API_KEY env var (no fallback — explicit per-branch)
- OpenRouter branch: uses OPENROUTER_API_KEY + vendor headers
- Generic branch: sends Authorization: Bearer <EMBEDDING_API_KEY> if set
- Unauth fallback: no header (localhost, no auth needed)
- Credential isolation: no cross-branch key leakage

.env.example + setup/install.md:
- Document EMBEDDING_API_KEY as optional for non-OpenRouter
  authenticated endpoints (vLLM --api-key, custom hosted services)

fix(embedding): make OpenRouter auth and headers conditional — unblock 100% local usage (#7) 
- Remove unconditional OPENROUTER_API_KEY check that blocked local providers
  (Ollama, vLLM, llama.cpp) from running without an API key
- Send OpenRouter-specific headers (HTTP-Referer, X-Title) only when
  EMBEDDING_API_BASE contains 'openrouter'
- Stop sending empty Authorization header to non-OpenRouter endpoints
- Update .env.example and setup/install.md to clarify that
  OPENROUTER_API_KEY is only required for OpenRouter

Closes #1

Claudio Drews 1281d7a778 fix: make embedding provider-agnostic via env vars 
- embedding.py: EMBEDDING_API_BASE and EMBEDDING_MODEL now read from env
  with OpenRouter defaults (preserves backward compatibility)
- .env.example: document embedding backend config with Qwen3 rationale
- setup/install.md: update prerequisite to reflect configurable backend
- layers/05-qdrant.md: add "Why Qwen3-Embedding-8B" section
  (multilingual, quality, speed, cost)

Closes #1
