Clean up unused files, organize structure, update docs

- Delete obsolete files: data_fetcher_old.py, market_old.py, base_strategy.py (root),
  strategy_sma_cross.py, and old architecture remnants (address_monitor.py,
  position_monitor.py, trade_log.py, wallet_data.py, whale_tracker.py)
- Delete zero-byte Docker artifacts and runtime files (clp_hedger.log,
  clp_hedger/hedge_status.json)
- Move one-off utility scripts to scripts/ directory
- Move example/template files to .temp/ directory
- Update .gitignore: add entries for clp_hedger.log, clp_hedger/hedge_status.json,
  Docker layer hash files, Using, Running, and backups/
- Update .dockerignore: add clp_hedger.log, clp_hedger/hedge_status.json, backups/
- Create example config files: _data/strategies.json.example,
  _data/backtesting_conf.json.example, _data/coin_precision.json.example
- Update GEMINI.md: remove outdated session summaries and duplicate review section
- Update review.md: add cleanup status section, update remaining recommendations
- Update MIGRATION_PLAN.md: mark completed phases, update file references
- Update DOCKER_MIGRATION_GUIDE.md: update import_csv.py path reference

 ### 3. Improve Project Structure
 
-- **Issue:** The root directory is cluttered with numerous Python scripts, making it difficult to distinguish between core application files, utility scripts, and old/example files.
+- **Issue:** The root directory is still somewhat cluttered with Python scripts.
 - **Proposal:**
-    - Create a `scripts/` directory and move all one-off utility and maintenance scripts into it.
     - Consider creating a `src/` or `app/` directory to house the core application source code (`main_app.py`, `trade_executor.py`, etc.), separating it clearly from configuration, data, and documentation.
 - **Benefit:** A cleaner, more organized project structure that is easier for new developers to understand.

 - **Proposal:**
     - Explicitly define the agent names and their corresponding environment variable keys in the proposed `_data/config.json` file. The `trade_executor` would then load only the agents specified in the configuration.
 - **Benefit:** Makes agent configuration more explicit and less prone to errors from stray environment variables.

-## Identified Unused/Utility Files
-
-The following files were identified as likely being unused by the core application, being obsolete, or serving as one-off utilities. It is recommended to **move them to a `scripts/` directory** or **delete them** if they are obsolete.
-
-### Obsolete / Old Versions:
-- `data_fetcher_old.py`
-- `market_old.py`
-- `base_strategy.py` (The one in the root directory; the one in `strategies/` is used).
-
-### One-Off Utility Scripts (Recommend moving to `scripts/`):
-- `!migrate_to_sqlite.py`
-- `import_csv.py`
-- `del_market_cap_tables.py`
-- `fix_timestamps.py`
-- `list_coins.py`
-- `create_agent.py`
-
-### Examples / Unused Code:
-- `basic_ws.py` (Appears to be an example file).
-- `backtester.py`
-- `strategy_sma_cross.py` (A strategy file in the root, not in the `strategies` folder).
-- `strategy_template.py`
-
-### Standalone / Potentially Unused Core Files:
-The following files seem to have their logic already integrated into the main multi-process application. They might be remnants of a previous architecture and may not be needed as standalone scripts.
-- `address_monitor.py`
-- `position_monitor.py`
-- `trade_log.py`
-- `wallet_data.py`
-- `whale_tracker.py`
-
-### Data / Log Files (Recommend archiving or deleting):
-- `hyperliquid_wallet_data_*.json` (These appear to be backups or logs).
