refactor: remove Smithery deployment mode

Smithery is no longer a supported deployment mode. Remove all Smithery-specific
code paths, middleware, configuration, and tests. This simplifies the codebase
by eliminating DeploymentMode enum, SmitheryConfigMiddleware, session config
context variables, and the smithery_main entrypoint.

Files deleted: Dockerfile.smithery, smithery.yaml, smithery_main.py
ADR-016 retained with deprecated status for historical reference.

> [!NOTE]
> **Looking for AI features inside Nextcloud?** Nextcloud also provides [Context Agent](https://github.com/nextcloud/context_agent), which powers the Assistant app and runs as an ExApp inside Nextcloud. See [docs/comparison-context-agent.md](docs/comparison-context-agent.md) for a detailed comparison of use cases.
## Quick Start
The fastest way to get started is via [Smithery](https://smithery.ai/server/@cbcoutinho/nextcloud-mcp-server) - no Docker or self-hosting required:
1. Visit the [Smithery marketplace page](https://smithery.ai/server/@cbcoutinho/nextcloud-mcp-server)
2. Click "Deploy" and configure:
- **Nextcloud URL**: Your Nextcloud instance (e.g., `https://cloud.example.com`)
- **Username**: Your Nextcloud username
- **App Password**: Generate one in Nextcloud → Settings → Security → Devices & sessions
> [!NOTE]
> Smithery runs in stateless mode without semantic search. For full features, use [Docker](#docker-self-hosted) or see [ADR-016](docs/ADR-016-smithery-stateless-deployment.md).

# ADR-016: Smithery Stateless Deployment for Multi-User Public Nextcloud Instances
**Status:** Proposed
**Status:** Deprecated (removed in v0.66.0)
**Date:** 2025-01-22
**Deprecated:** 2026-03-22 — Smithery deployment mode has been removed. Smithery sunsetted its free tier and third-party hosting conflicts with the project's privacy-first design. See ADR-022 for rationale.
**Deciders:** Development Team
**Related:** ADR-004 (OAuth), ADR-007 (Background Vector Sync), ADR-015 (Unified Provider)

### 5. Smithery Stateless
**Use Case:** Multi-tenant SaaS deployment via Smithery platform. Fully stateless.
Enabled by `SMITHERY_DEPLOYMENT=true`.
#### MCP Client → MCP Server → Nextcloud
```
MCP Client MCP Server Nextcloud
│ │ │
│── SSE Connect ─────────────▶│ │
│ ?nextcloud_url=... │ │
│ &username=... │ │
│ &app_password=... │ │
│ │── SmitheryConfigMiddleware │

│ │ │
│── MCP Request ─────────────▶│ │

│ │ NextcloudClient │
│ │ │
│ │── HTTP + BasicAuth ───────▶│
│ │ (from session params) │
│ │◀── API Response ───────────│
│◀── Tool Result ─────────────│ │
```
**Key characteristics:**
- Configuration passed via URL query parameters (Smithery `configSchema`)
- No persistent state - client created fresh per request
- No OAuth infrastructure
- No background sync support (stateless)
- No admin UI available
**Required session parameters:**
- `nextcloud_url`: Nextcloud instance URL
- `username`: Nextcloud username
- `app_password`: Nextcloud app password
**Implementation:** `context.py:108-184` - `_get_client_from_session_config()` creates client from session params
#### Background Sync
Not supported. Smithery mode is fully stateless with no credential storage.
#### Astrolabe Integration
Not applicable. Smithery deployments don't integrate with Astrolabe.
