fix: patch client.gen.ts for Deno compatibility during generation

Add a post-generation patch step to generate-clients.sh that removes the hey-api internal 'client' field from the RequestInit spread in client.gen.ts. Deno's Request constructor rejects 'client' because it conflicts with the Deno.HttpClient option name.
fix: remove broken link to non-existent n8n blog post in streamlit post

+# Hindsight API
+
+**Memory System for AI Agents** — Temporal + Semantic + Entity Memory Architecture using PostgreSQL with pgvector.
+
+Hindsight gives AI agents persistent memory that works like human memory: it stores facts, tracks entities and relationships, handles temporal reasoning ("what happened last spring?"), and forms opinions based on configurable disposition traits.
+
+## Installation
+
+```bash
+pip install hindsight-api
+```
+
+## Quick Start
+
+### Run the Server
+
+```bash
+# Set your LLM provider
+export HINDSIGHT_API_LLM_PROVIDER=openai
+export HINDSIGHT_API_LLM_API_KEY=sk-xxxxxxxxxxxx
+
+# Start the server (uses embedded PostgreSQL by default)
+hindsight-api
+```
+
+The server starts at http://localhost:8888 with:
+- REST API for memory operations
+- MCP server at `/mcp` for tool-use integration
+
+### Use the Python API
+
+```python
+from hindsight_api import MemoryEngine
+
+# Create and initialize the memory engine
+memory = MemoryEngine()
+await memory.initialize()
+
+# Create a memory bank for your agent
+bank = await memory.create_memory_bank(
+    name="my-assistant",
+    background="A helpful coding assistant"
+)
+
+# Store a memory
+await memory.retain(
+    memory_bank_id=bank.id,
+    content="The user prefers Python for data science projects"
+)
+
+# Recall memories
+results = await memory.recall(
+    memory_bank_id=bank.id,
+    query="What programming language does the user prefer?"
+)
+
+# Reflect with reasoning
+response = await memory.reflect(
+    memory_bank_id=bank.id,
+    query="Should I recommend Python or R for this ML project?"
+)
+```
+
+## CLI Options
+
+```bash
+hindsight-api --help
+
+# Common options
+hindsight-api --port 9000          # Custom port (default: 8888)
+hindsight-api --host 127.0.0.1     # Bind to localhost only
+hindsight-api --workers 4          # Multiple worker processes
+hindsight-api --log-level debug    # Verbose logging
+```
+
+## Configuration
+
+Configure via environment variables:
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `HINDSIGHT_API_DATABASE_URL` | PostgreSQL connection string | `pg0` (embedded) |
+| `HINDSIGHT_API_LLM_PROVIDER` | `openai`, `anthropic`, `gemini`, `groq`, `ollama`, `lmstudio` | `openai` |
+| `HINDSIGHT_API_LLM_API_KEY` | API key for LLM provider | - |
+| `HINDSIGHT_API_LLM_MODEL` | Model name | `gpt-4o-mini` |
+| `HINDSIGHT_API_HOST` | Server bind address | `0.0.0.0` |
+| `HINDSIGHT_API_PORT` | Server port | `8888` |
+
+### Example with External PostgreSQL
+
+```bash
+export HINDSIGHT_API_DATABASE_URL=postgresql://user:pass@localhost:5432/hindsight
+export HINDSIGHT_API_LLM_PROVIDER=groq
+export HINDSIGHT_API_LLM_API_KEY=gsk_xxxxxxxxxxxx
+
+hindsight-api
+```
+
+## Docker
+
+```bash
+docker run --rm -it -p 8888:8888 \
+  -e HINDSIGHT_API_LLM_API_KEY=$OPENAI_API_KEY \
+  -v $HOME/.hindsight-docker:/home/hindsight/.pg0 \
+  ghcr.io/vectorize-io/hindsight:latest
+```
+
+## MCP Server
+
+For local MCP integration without running the full API server:
+
+```bash
+hindsight-local-mcp
+```
+
+This runs a stdio-based MCP server that can be used directly with MCP-compatible clients.
+
+## Key Features
+
+- **Multi-Strategy Retrieval (TEMPR)** — Semantic, keyword, graph, and temporal search combined with RRF fusion
+- **Entity Graph** — Automatic entity extraction and relationship tracking
+- **Temporal Reasoning** — Native support for time-based queries
+- **Disposition Traits** — Configurable skepticism, literalism, and empathy influence opinion formation
+- **Three Memory Types** — World facts, bank actions, and formed opinions with confidence scores
+

+"""Add GIN index on source_memory_ids for observation lookup performance
+
+Without this index, queries using the array overlap operator (&&) or array
+containment (@>) on source_memory_ids require a full sequential scan over all
+observation memory_units. At ~77k observations this was measured at 45ms per
+query, becoming a bottleneck during consolidation recall (57-64s timeouts) and
+user recall (18-27s average).
+
+The GIN index reduces these queries to index scans: 45ms → 0.049ms (927x
+speedup). Recall dropped from 18-27s to ~6s, and consolidation recall
+stabilised from timeout to ~15s.
+
+Created with CONCURRENTLY so the migration does not block reads or writes.
+CONCURRENTLY requires running outside a transaction block, so the migration
+emits an explicit COMMIT before the statement and uses IF NOT EXISTS for
+idempotency.

+"""Add internal_id to banks and per-(bank, fact_type) partial HNSW indexes
+
+Revision ID: d5e6f7a8b9c0
+Revises: a3b4c5d6e7f8
+Create Date: 2026-03-11
+
+This migration:
+1. Adds internal_id UUID column to banks (stable identifier for index naming)
+2. Drops the global HNSW index (competes with per-bank partial indexes)
+3. Creates per-(bank_id, fact_type) partial HNSW indexes for all existing banks
+   (new banks get indexes created at bank-creation time via bank_utils.create_bank_hnsw_indexes)
+
+Why per-(bank, fact_type) indexes:
+- fact_type-only partial indexes are never chosen by the planner when bank_id is in the WHERE
+  clause, because the idx_memory_units_bank_id B-tree index always wins at planning time.
+- Per-(bank, fact_type) partial indexes have both predicates matching → planner selects them.
+- The global HNSW index competes for larger partitions (world, observation) and must be dropped.
+
+For large deployments, create indexes CONCURRENTLY before running this migration:
+    SELECT internal_id, bank_id FROM banks;
+    -- for each bank and each fact_type in (world, experience, observation):
+    CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_mu_emb_{ft}_{uid16}
+        ON memory_units USING hnsw (embedding vector_cosine_ops)
+        WHERE fact_type = '{ft}' AND bank_id = '{bank_id}';

+Two-pass cleanup of memory_units rows that were never removed by earlier bugs:
+
+Pass 1 — any fact_type, bank gone:
+  memory_units whose bank_id no longer exists in banks.  These accumulate when
+  a bank is deleted without a proper cascade (no FK from memory_units to banks
+  exists in the schema).
+
+Pass 2 — observations only, all sources gone:
+  observation rows whose bank still exists but every source_memory_id points
+  to a deleted memory unit.  These were left behind before PR #580 fixed the
+  chunk FK cascade and before delete_document() called
+  _delete_stale_observations_for_memories.
