Restructure AgenticCodeExecution: examples/ per-domain layout

Sync with standalone Agentic-Code-Execution repo refactor:
- Replace tools-server/, system-prompts/, data/ with examples/{domain}/ structure
- Each domain (retail, airline, stocks, banking, triage) is self-contained
- Remove start_all.sh (unused)
- Update docker-compose.yml, Dockerfile, .gitignore, README paths
- Update MCP server imports and default DB/session paths

 ### Docker notes
 
-- Compose mounts `./data` into the tools container at `/data`.
-- Default DB paths: `/data/<domain>/db.json`. Override with `RETAIL_DB_PATH`, `AIRLINE_DB_PATH`, `STOCKS_DB_PATH`, `BANKING_DB_PATH`.
+- Compose builds the tools-server image from `examples/Dockerfile`.
+- Default DB paths are resolved relative to each domain's directory (e.g. `examples/retail/data/db.json`). Override with `RETAIL_DB_PATH`, `AIRLINE_DB_PATH`, `STOCKS_DB_PATH`, `BANKING_DB_PATH`.
 - `NO_PROXY`/`no_proxy` is set for internal service-to-service calls.
 - If `docker compose build` fails behind a proxy, see [Troubleshooting](#docker-build-fails-behind-proxy).
