Fix ollama not reachable from host due to hardcoded OLLAMA_HOST in entrypoint

The IPEX-LLM bundled start-ollama.sh hardcodes OLLAMA_HOST=127.0.0.1 and
OLLAMA_KEEP_ALIVE=10m, overriding docker-compose environment variables and
preventing external connections through Docker port mapping.

- Add custom start-ollama.sh that honours env vars with sensible defaults
- Mount it read-only into the container
- Fix LD_LIBRARY_PATH env var syntax (: -> =)
- Add .gitignore for IDE/swap/webui data files
- Update CHANGELOG and README with fix documentation

+### Custom `start-ollama.sh` entrypoint
+
+The upstream IPEX-LLM portable zip ships a `start-ollama.sh` that hardcodes
+`OLLAMA_HOST=127.0.0.1` and `OLLAMA_KEEP_ALIVE=10m`, preventing the container
+from accepting connections via Docker port mapping and ignoring Compose
+environment overrides.
+
+This repo includes a corrected `start-ollama.sh` (mounted read-only into the
+container) that honours environment variables set in `docker-compose.yml`,
+falling back to sensible defaults (`0.0.0.0:11434`, `24h`).
