fix: include tags, created_at, proof_count in graph table_rows

The graph endpoint's table_rows response was missing three fields that
the control plane UI expects:
- tags: memory unit tags (shown in Tags column)
- created_at: creation timestamp (shown in Created column for mental models)
- proof_count: source memory count (shown in Sources column for mental models)

All three columns exist on the memory_units table but were not being
selected or included in the response.

 Hindsight is an agent memory system that provides long-term memory for AI agents using biomimetic data structures. Memories are organized as:
 - **World facts**: General knowledge ("The sky is blue")
 - **Experience facts**: Personal experiences ("I visited Paris in 2023")
-- **Opinion facts**: Beliefs with confidence scores ("Paris is beautiful" - 0.9 confidence)
-- **Observations**: Complex mental models derived from reflection
+- **Mental models**: Consolidated knowledge synthesized from facts ("User prefers functional programming patterns")

+
+CONSOLIDATION_SYSTEM_PROMPT = """You are a memory consolidation system. Your job is to convert facts into durable knowledge (mental models) and merge with existing knowledge when appropriate.
+
+You must output ONLY valid JSON with no markdown formatting, no code blocks, and no additional text.
+
+## EXTRACT DURABLE KNOWLEDGE, NOT EPHEMERAL STATE
+Facts often describe events or actions. Extract the DURABLE KNOWLEDGE implied by the fact, not the transient state.
+
+Examples of extracting durable knowledge:
+- "User moved to Room 203" -> "Room 203 exists" (location exists, not where user is now)
+- "User visited Acme Corp at Room 105" -> "Acme Corp is located in Room 105"
+- "User took the elevator to floor 3" -> "Floor 3 is accessible by elevator"
+- "User met Sarah at the lobby" -> "Sarah can be found at the lobby"
+
+DO NOT track current user position/state as knowledge - that changes constantly.
+DO track permanent facts learned from the user's actions.
+
+## PRESERVE SPECIFIC DETAILS
+Keep names, locations, numbers, and other specifics. Do NOT:
+- Abstract into general principles
+- Generate business insights
+- Make knowledge generic
+
+GOOD examples:
+- Fact: "John likes pizza" -> "John likes pizza"
+- Fact: "Alice works at Google" -> "Alice works at Google"
+
+BAD examples:
+- "John likes pizza" -> "Understanding dietary preferences helps..." (TOO ABSTRACT)
+- "User is at Room 203" -> "User is currently at Room 203" (EPHEMERAL STATE)
+
+## MERGE RULES (when comparing to existing mental models):
+1. REDUNDANT: Same information worded differently → update existing
+2. CONTRADICTION: Opposite information about same topic → update with history (e.g., "used to X, now Y")
+3. UPDATE: New state replacing old state → update with history
+
+## TAG ROUTING RULES:
+Tags define visibility scopes. The fact and each mental model have tags (can be empty = global).
+
+| Fact Tags | Model Tags | Action |
+|-----------|------------|--------|
+| [alice] | [alice] | UPDATE the model (same scope) |
+| [alice] | [] | UPDATE the model (global absorbs all scopes) |
+| [alice] | [bob] | CREATE new untagged model (cross-scope insight) |
+| [] | [alice] | UPDATE the model (untagged facts can update any scope) |
+| [] | [] | UPDATE the model (global to global) |
+
+When NO existing model matches the fact's topic: CREATE new model with fact's tags.
+
+## MULTIPLE ACTIONS:
+One fact can trigger MULTIPLE actions. For example:
+- Update a scoped model [alice] about pizza preferences
+- AND update a global model [] about pizza in general
+
+Output an ARRAY of actions (can be empty, one, or many).
+
+## CRITICAL RULES:
+- NEVER merge facts about DIFFERENT people
+- NEVER merge unrelated topics (food preferences vs work vs hobbies)
+- When merging contradictions, capture the CHANGE (before → after)
+- Keep mental models focused on ONE specific topic per person
+- Cross-scope insights (alice's fact about bob's topic) become UNTAGGED (global)
+- The "text" field MUST contain durable knowledge, not ephemeral state"""
