initial: identity resolution plugin

- Plugin manifest (plugin.yaml) with pre_gateway_dispatch + on_session_start hooks
- /identity slash command for config management
- Honcho injector patch docs (6 lines in plugins/memory/honcho/__init__.py)
- Config file at /opt/data/identity-config.json for persistence
- Kanban task body convention: context_peer: <name>
- Sample config with thierry/catherine mappings

Architecture: user-installed plugin (hooks + CLI) + 6-line Honcho bundled plugin change

+# Enforcing context_peer in the kanban-worker skill
+
+Profiles (Claire, Ashley, Finn, Matt) must include `context_peer: <name>` in
+every `kanban_create` call. This document covers how to enforce it.
+
+## Option 1: Profile system prompt (recommended, no code change)
+
+Add to each profile's system prompt or skill config:
+
+> When creating a kanban task with `kanban_create`, you MUST include
+> a `context_peer: <name>` metadata block in the task body. The peer
+> must be the intended user's Honcho peer name (e.g., `thierry`,
+> `catherine`), not your own profile name.
+>
+> Format:
+> ```metadata
+> context_peer: thierry
+> ```
+
+## Option 2: kanban-create wrapper tool
+
+Create a custom tool in `/opt/data/hermes-tools/` that wraps `kanban_create`
+and rejects calls without `context_peer` in the body.
+
+This approach requires the persistent tools volume (already used for QET,
+Gitea, Ollama tools) and a tool registration in the Docker entrypoint.
+
+## Option 3: Slash command validation
+
+The `/identity` command includes a `validate` subcommand that checks recent
+kanban tasks for missing `context_peer` fields.
+
+```bash
+/identity validate
+```

+# Honcho Injector Patch
+
+The identity plugin cannot directly inject `runtime_user_peer_name` into
+Honcho from a user-installed hook (the hook system only allows message
+rewrite/skip, not user_id modification). Instead, we add ~6 lines in the
+bundled Honcho plugin's session initialization.
+
+## File
+
+`plugins/memory/honcho/__init__.py` — line ~362
+
+## The change
+
+### Before
+
+```python
+runtime_user_peer_name=kwargs.get("user_id") or None,
+```
+
+### After
+
+```python
+runtime_user_peer_name=kwargs.get("user_id") or _resolve_identity_peer(),
+```
+
+### Add this function in the same file (or import from the identity plugin)
+
+```python
+def _resolve_identity_peer() -> str | None:
+    """Resolve peer name from env vars and identity config.
+
+    Priority: HERMES_HONCHO_PEER_NAME → kanban task body context_peer
+    → kanban board config → None (falls through to Honcho default).
+    """

+                        if m:
+                            return m.group(1)
+                finally:

+            # Check kanban board config
+            board = os.environ.get("HERMES_KANBAN_BOARD")

+            return cfg.get("fallback_peer")
+        except Exception:
+            pass
+
+    return None
+```
+
+## How it works
+
+1. When a **gateway session** starts, `kwargs["user_id"]` carries the platform
+   ID (Discord snowflake, Telegram UID). The identity config file maps these
+   to canonical peer names. The injector is bypassed — normal flow.
+
+2. When a **kanban worker** starts, `kwargs["user_id"]` is None (no gateway).
+   The injector kicks in:
+
+   a. Checks `HERMES_HONCHO_PEER_NAME` env var (set by a future dispatcher
+      enhancement or manually).
+
+   b. Reads the kanban task body from the SQLite database, extracts
+      `context_peer: <name>` from the body.
+
+   c. Falls back to the board-level config from identity-config.json.
+
+   d. If nothing resolves → returns None → Honcho creates `user-default-*`
+      as today (safe fallback).
+
+## Why not modify the kanban dispatcher?
+
+The kanban dispatcher (`hermes_cli/kanban_db.py:_default_spawn`) is core
+Hermes code. We avoid touching it. Instead, the Honcho injector reads the
+task directly from the kanban DB using env vars that are already set
+(`HERMES_KANBAN_TASK`, `HERMES_KANBAN_DB`, `HERMES_KANBAN_BOARD`).
+
+This adds ~10 microseconds to worker startup — negligible.
+
+## Compatibility
+
+- If the identity plugin is removed, the injector function returns None and
+  Honcho behaves exactly as before.
+- If the config file is missing, same safe fallback.
+- No data loss risk.
