Environment variables not documented — 30+ env vars across codebase

[rohitg00]

Problem

~30 environment variables are used across the codebase but there is no single reference document or `.env.example` file.

Env Vars Found

• Engine: `III_ENGINE_URL`, `III_REST_PORT`, `III_STREAMS_PORT`
• LLM: `ANTHROPIC_API_KEY`, `ANTHROPIC_MODEL`, `GEMINI_API_KEY`, `GEMINI_MODEL`, `OPENROUTER_API_KEY`, `OPENROUTER_MODEL`, `OPENAI_API_KEY`
• Embedding: `VOYAGE_API_KEY`, `COHERE_API_KEY`, `EMBEDDING_PROVIDER`, `BM25_WEIGHT`, `VECTOR_WEIGHT`
• Auth: `AGENTMEMORY_SECRET`, `AGENTMEMORY_URL`
• Limits: `TOKEN_BUDGET`, `MAX_OBS_PER_SESSION`, `MAX_TOKENS`
• Features: `FALLBACK_PROVIDERS`, `GRAPH_EXTRACTION_ENABLED`, `GRAPH_EXTRACTION_BATCH_SIZE`, `CONSOLIDATION_ENABLED`, `CONSOLIDATION_DECAY_DAYS`
• Claude: `CLAUDE_MEMORY_BRIDGE`, `CLAUDE_PROJECT_PATH`, `CLAUDE_MEMORY_LINE_BUDGET`
• Team: `TEAM_ID`, `USER_ID`, `TEAM_MODE`
• Snapshot: `SNAPSHOT_ENABLED`, `SNAPSHOT_INTERVAL`, `SNAPSHOT_DIR`
• Standalone: `STANDALONE_MCP`, `STANDALONE_PERSIST_PATH`
• Viewer: `VIEWER_ALLOWED_ORIGINS`

Suggested Fix

Add a `.env.example` file and/or a configuration reference section in the README.

Resolved in v0.6.0 (PR #76). README now documents all 30+ environment variables in a complete .env template covering LLM providers, embedding providers, search weights, fallback chain, auth, engine connection, memory tuning, Claude bridge, standalone MCP, knowledge graph, consolidation, team memory, and git snapshots.
