docs: add Supermemory to memory providers docs, env vars, CLI reference

- Add full Supermemory section to memory-providers.md with config table,
  tools, setup instructions, and key features
- Update provider count from 7 to 8 across memory.md and memory-providers.md
- Add SUPERMEMORY_API_KEY to environment-variables.md
- Add Supermemory to integrations/providers.md optional API keys table
- Add supermemory to cli-commands.md provider list
- Add Supermemory to profile isolation section (config file providers)

+# Supermemory Memory Provider
+
+Semantic long-term memory with profile recall, semantic search, explicit memory tools, and session-end conversation ingest.
+
+## Requirements
+
+- `pip install supermemory`
+- Supermemory API key from [supermemory.ai](https://supermemory.ai)
+
+## Setup
+
+```bash
+hermes memory setup    # select "supermemory"
+```
+
+Or manually:
+
+```bash
+hermes config set memory.provider supermemory
+echo 'SUPERMEMORY_API_KEY=your-key-here' >> ~/.hermes/.env
+```
+
+## Config
+
+Config file: `$HERMES_HOME/supermemory.json`
+
+| Key | Default | Description |
+|-----|---------|-------------|
+| `container_tag` | `hermes` | Container tag used for search and writes |
+| `auto_recall` | `true` | Inject relevant memory context before turns |
+| `auto_capture` | `true` | Store cleaned user-assistant turns after each response |
+| `max_recall_results` | `10` | Max recalled items to format into context |
+| `profile_frequency` | `50` | Include profile facts on first turn and every N turns |
+| `capture_mode` | `all` | Skip tiny or trivial turns by default |
+| `entity_context` | built-in default | Extraction guidance passed to Supermemory |
+| `api_timeout` | `5.0` | Timeout for SDK and ingest requests |
+
+## Tools
+
+| Tool | Description |
+|------|-------------|
+| `supermemory_store` | Store an explicit memory |
+| `supermemory_search` | Search memories by semantic similarity |
+| `supermemory_forget` | Forget a memory by ID or best-match query |
+| `supermemory_profile` | Retrieve persistent profile and recent context |
+
+## Behavior
+
+When enabled, Hermes can:
+
+- prefetch relevant memory context before each turn
+- store cleaned conversation turns after each completed response
+- ingest the full session on session end for richer graph updates
+- expose explicit tools for search, store, forget, and profile access

+### Supermemory
+
+Semantic long-term memory with profile recall, semantic search, explicit memory tools, and session-end conversation ingest via the Supermemory graph API.
+
+| | |
+|---|---|
+| **Best for** | Semantic recall with user profiling and session-level graph building |
+| **Requires** | `pip install supermemory` + [API key](https://supermemory.ai) |
+| **Data storage** | Supermemory Cloud |
+| **Cost** | Supermemory pricing |
+
+**Tools:** `supermemory_store` (save explicit memories), `supermemory_search` (semantic similarity search), `supermemory_forget` (forget by ID or best-match query), `supermemory_profile` (persistent profile + recent context)
+
+**Setup:**
+```bash
+hermes memory setup    # select "supermemory"
+# Or manually:
+hermes config set memory.provider supermemory
+echo 'SUPERMEMORY_API_KEY=your-key-here' >> ~/.hermes/.env
+```
+
+**Config:** `$HERMES_HOME/supermemory.json`
+
+| Key | Default | Description |
+|-----|---------|-------------|
+| `container_tag` | `hermes` | Container tag used for search and writes |
+| `auto_recall` | `true` | Inject relevant memory context before turns |
+| `auto_capture` | `true` | Store cleaned user-assistant turns after each response |
+| `max_recall_results` | `10` | Max recalled items to format into context |
+| `profile_frequency` | `50` | Include profile facts on first turn and every N turns |
+| `capture_mode` | `all` | Skip tiny or trivial turns by default |
+| `api_timeout` | `5.0` | Timeout for SDK and ingest requests |
+
+**Key features:**
+- Automatic context fencing — strips recalled memories from captured turns to prevent recursive memory pollution
+- Session-end conversation ingest for richer graph-level knowledge building
+- Profile facts injected on first turn and at configurable intervals
+- Trivial message filtering (skips "ok", "thanks", etc.)

 ## Profile Isolation
 
 Each provider's data is isolated per [profile](/docs/user-guide/profiles):
 
 - **Local storage providers** (Holographic, ByteRover) use `$HERMES_HOME/` paths which differ per profile
-- **Config file providers** (Honcho, Mem0, Hindsight) store config in `$HERMES_HOME/` so each profile has its own credentials
+- **Config file providers** (Honcho, Mem0, Hindsight, Supermemory) store config in `$HERMES_HOME/` so each profile has its own credentials
 - **Cloud providers** (RetainDB) auto-derive profile-scoped project names
 - **Env var providers** (OpenViking) are configured via each profile's `.env` file
