feat: add reverse proxy support (#346)

* improve

* fix: update integration test to use modern 'docker compose' command

- Replace 'docker-compose' with 'docker compose' (Docker Compose v2+)
- Add fallback to legacy docker-compose command for compatibility
- Fixes test failures on systems using Docker Compose plugin

* ci: trigger test rerun

* fix: make docker-compose detection more robust for CI

- Add get_docker_compose_command() to detect available command
- Use shutil.which() to check command availability
- Dynamically use correct command (docker compose vs docker-compose)
- Should work in both modern and legacy Docker environments

* fix: docker-compose networking in base path integration test

Fix connection refused error in test_reverse_proxy_simple_config by
handling host vs bridge networking modes correctly:

- Linux (host mode): nginx listens on 18080 directly, no port mapping
- Mac/Windows (bridge mode): nginx listens on 80, mapped to 18080

With host networking, port mappings in docker-compose don't work since
the container binds directly to the host's network namespace.

+# Nginx Reverse Proxy with Custom Base Path
+
+Deploy Hindsight API under `/hindsight` (or any custom path) using Nginx reverse proxy.
+
+## Quick Start (Published Image - API Only)
+
+```bash
+docker-compose up
+```
+
+- **API:** http://localhost:8080/hindsight/docs
+- **Control Plane:** http://localhost:9999 (direct access, not proxied)
+
+## Full Stack with Custom Base Path (Requires Build)
+
+**Important:** You cannot rebuild from the published image with build args. You must build from source.
+
+### Build from Source with Custom Base Path
+
+1. **Clone the repository** (if you haven't):
+```bash
+git clone https://github.com/vectorize-io/hindsight.git
+cd hindsight
+```
+
+2. **Build with base path**:
+```bash
+docker build \
+  --build-arg NEXT_PUBLIC_BASE_PATH=/hindsight \
+  -f docker/standalone/Dockerfile \
+  -t hindsight:custom \
+  .
+```
+
+3. **Update docker-compose.yml** to use your built image:
+```yaml
+services:
+  hindsight:
+    image: hindsight:custom  # ← Change this
+    environment:
+      HINDSIGHT_API_BASE_PATH: /hindsight
+      NEXT_PUBLIC_BASE_PATH: /hindsight
+```
+
+4. **Update nginx.conf** to handle Control Plane routes (see below)
+
+5. **Run**:
+```bash
+docker-compose up
+```
+
+### Required nginx.conf for Full Stack
+
+Replace the current `nginx.conf` with this to proxy both API and Control Plane:
+
+```nginx
+events { worker_connections 1024; }
+
+http {
+    include /etc/nginx/mime.types;
+    default_type application/octet-stream;
+
+    upstream hindsight_api { server hindsight:8888; }
+    upstream hindsight_cp { server hindsight:9999; }
+
+    server {
+        listen 80;
+
+        # API
+        location ~ ^/hindsight/(docs|openapi\.json|health|metrics|v1|mcp) {
+            proxy_pass http://hindsight_api;
+            proxy_set_header Host $http_host;
+        }
+
+        # Control Plane static files
+        location ~ ^/hindsight/_next/ {
+            proxy_pass http://hindsight_cp;
+            proxy_set_header Host $http_host;
+        }
+
+        # Control Plane UI
+        location /hindsight {
+            proxy_pass http://hindsight_cp;
+            proxy_set_header Host $http_host;
+        }
+
+        location = / { return 301 /hindsight; }
+    }
+}
+```
+
+### Why Build is Required
+
+Next.js requires `basePath` at **build time**. The published image was built without a custom base path, so you must rebuild from source with the `NEXT_PUBLIC_BASE_PATH` build arg to deploy the Control Plane under a subpath.
+
+The API works without rebuild because `HINDSIGHT_API_BASE_PATH` is a runtime environment variable.

+# Note: This configuration uses the published image (no build required).

+To deploy Hindsight under a subpath (e.g., `example.com/hindsight/`):
+
+1. Set both environment variables to the same path:
+   ```bash
+   HINDSIGHT_API_BASE_PATH=/hindsight
+   NEXT_PUBLIC_BASE_PATH=/hindsight
+   ```
+
+2. Configure your reverse proxy to:
+   - Forward `/hindsight/*` requests to Hindsight
+   - Preserve the full path in forwarded requests
+   - Set appropriate proxy headers (X-Forwarded-Proto, X-Forwarded-For)
+
+**Example: Nginx Configuration**
+
+```nginx
+location /hindsight/ {
+    proxy_pass http://localhost:8888/;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto $scheme;
+}
+```
+
+**Example: Traefik Configuration**
+
+```yaml
+http:
+  routers:
+    hindsight:
+      rule: "PathPrefix(`/hindsight`)"
+      service: hindsight
+      middlewares:
+        - hindsight-stripprefix
+
+  middlewares:
+    hindsight-stripprefix:
+      stripPrefix:
+        prefixes:
+          - "/hindsight"
+
+  services:
+    hindsight:
+      loadBalancer:
+        servers:
+          - url: "http://localhost:8888"
+```
+
+**Important Notes:**
+- The base path must start with `/` and should NOT end with `/`
+- Both API and Control Plane should use the same base path
+- After setting environment variables, restart both services
+- OpenAPI docs will be available at `<base-path>/docs` (e.g., `/hindsight/docs`)
+
+**Complete Examples:**
+
+See `docker/compose-examples/` directory for:
+- Nginx configuration files (`simple.conf`, `api-and-control-plane.conf`)
+- Docker Compose setups (`docker-compose.yml`, `reverse-proxy-only.yml`)
+- Traefik and other reverse proxy examples

 E2E and integration tests for Hindsight API that require a running server.
 
-## Running Tests
+## Test Types
 
-1. Start the API server:
+### 1. Tests with External Server
-   ```bash
+Tests like `test_mcp_e2e.py` expect a server to already be running.
-   ./scripts/dev/start-api.sh
-   ```
 
-2. Run the tests:
+**Running:**
-   ```bash
+```bash
-   cd hindsight-integration-tests
+# Start the API server
-   HINDSIGHT_API_URL=http://localhost:8888 uv run pytest tests/ -v
+./scripts/dev/start-api.sh
-   ```
+
+# Run tests
+cd hindsight-integration-tests
+HINDSIGHT_API_URL=http://localhost:8888 uv run pytest tests/test_mcp_e2e.py -v
+```
+
+### 2. Self-Contained Tests
+Tests like `test_base_path_deployment.py` manage their own server lifecycle and use docker-compose.
+
+**Running:**
+```bash
+cd hindsight-integration-tests
+
+# Run with pytest
+uv run pytest tests/test_base_path_deployment.py -v
+
+# Or run directly for nice output
+uv run python tests/test_base_path_deployment.py
+```
+
+**Requirements:**
+- Docker and docker-compose installed (for reverse proxy test)
+- No nginx required on host!
+
+**What it tests:**
+- ✅ API with base path (direct server)
+- ✅ Full reverse proxy via docker-compose + Nginx
+- ✅ Regression: API without base path
+- ✅ Full retain/recall workflow
+
+These tests:
+- Start their own API servers on dedicated ports (18888-18891)
+- Use docker-compose to test actual deployment scenarios
+- Run in parallel with other tests (no port conflicts)
+- Clean up automatically
+
+## Running All Tests
+
+```bash
+cd hindsight-integration-tests
+uv run pytest tests/ -v
+```
+
+This runs both types. Self-contained tests won't conflict with the external server.
 
 ## Environment Variables
 
-- `HINDSIGHT_API_URL` - Base URL of the running Hindsight API (default: `http://localhost:8888`)
+- `HINDSIGHT_API_URL` - Base URL for external-server tests (default: `http://localhost:8888`)

+Integration test for base path deployment using Docker Compose.

+1. API with base path (direct, no proxy)
+2. Full stack via docker-compose with Nginx reverse proxy
+3. Regression: API without base path still works
