fix: separate analyses dir so caching works with read-only recordings mount

Browse Source 
The Docker web container mounts ./recordings as :ro, causing every cache
write to fail silently (PermissionError swallowed by bare except).

Fix: add --analyses-dir flag (default: <recordings>/analyses for local runs).
docker-compose.yml adds ./analyses:/analyses (writable) and passes
--analyses-dir /analyses to web.py. Cache write failures now print a
warning instead of being swallowed silently.

**Log file in Docker:** The recorder always logs to stdout, so `docker compose logs -f` shows live output. To persist logs on the host, set `log_file = /app/recordings/recorder.log` in `config.ini` (the `recordings` directory is the bind mount).
**Analysis cache in Docker:** The web container mounts `./recordings` read-only, so analysis cache files are written to a separate `./analyses` bind mount (mapped to `/analyses` inside the container). This directory is created automatically by Docker Compose on first run. Cache files are stored as `analyses/<filename>.analysis.json` on the host.
**File retention:** Individual recordings can be deleted from the web UI. For bulk / automated cleanup, add a cron job on the host:
```bash
# Delete recordings older than 30 days
