chore: enhance .gitignore and remove obsolete documentation files

- Reorganize .gitignore with categorized sections for better maintainability
- Add comprehensive ignore patterns for Python, Node.js, databases, logs, and build artifacts
- Add project-specific ignore rules for coordinator, explorer, and deployment files
- Remove outdated documentation: BITCOIN-WALLET-SETUP.md, LOCAL_ASSETS_SUMMARY.md, README-CONTAINER-DEPLOYMENT.md, README-DOMAIN-DEPLOYMENT.md
```

+# Ollama GPU Provider Test Skill
+
+This skill runs an end-to-end client → coordinator → GPU miner → receipt flow using an Ollama prompt.
+
+## Overview
+
+The test submits a prompt (default: "hello") to the coordinator via the host proxy, waits for completion, and verifies that the job result and signed receipt are returned.
+
+## Prerequisites
+
+- Host GPU miner running and registered (RTX 4060 Ti + Ollama)
+- Incus proxy forwarding `127.0.0.1:18000` → container `127.0.0.1:8000`
+- Coordinator running in container (`coordinator-api.service`)
+- Receipt signing key configured in `/opt/coordinator-api/src/.env`
+
+## Test Command
+
+```bash
+python3 cli/test_ollama_gpu_provider.py --url http://127.0.0.1:18000 --prompt "hello"
+```
+
+## Expected Outcome
+
+- Job reaches `COMPLETED`
+- Output returned from Ollama
+- Receipt present with a `receipt_id`
+
+## Notes
+
+- Use `--timeout` to allow longer runs for large models.
+- If the receipt is missing, verify `receipt_signing_key_hex` is set and restart the coordinator.
