feat(backend): unify boot process and refactor route properties

- Added scripts/haul.sh, setup_auth.py, and setup_eve_data.py for simplified SSO and CSV data bootstrapping.
- Refactored `Ship` and `RouteStep` properties across route planning modules to utilize dictionaries instead of strict dataclass attributes.
- Re-aligned route limits, reducing upfront capital risk values in `arbitrage.py` and updating ship metrics in `manager.py`.
- Updated `.gitignore`, `.env.example`, and created AI-assistant prompt configuration.
- Added comprehensive "Getting Started" guides to the README and initialized CHANGELOG.md.

+## [Unreleased]
+
+### Added
+- `scripts/haul.sh` CLI for unified backend/frontend dependency checking, running, and EVE data bootstrapping.
+- `scripts/setup_auth.py` and `scripts/setup_eve_data.py` scripts to fetch OAuth credentials and base CSV game data.
+- `.env.example` to ease SSO configuration.
+- Custom Copilot Chat prompt for documenting changes under `.github/prompts`.
+
+### Changed
+- Refactored `backend/src/manager.py` to fix graph instantiations, updated ship properties to feature larger cargo, lower subwarp/warp speed, and accurately lower ship ISK value.
+- Re-aligned route and item capital checks across `backend/src/manager.py` and `backend/src/pathfinder.py` by transitioning the `Ship` attribute references from dataclasses to dictionaries.
+- Reduced initial max capital layout cap to `20,000,000` in `backend/src/arbitrage.py` to be more cautious about early-game up-front ISK demands.
+- Updated `backend/src/loader.py` to handle edge cases where `solar_system_id` was returned as 'None'.
+- Enhanced graph generation to reliably build its parent directory for `PATHS_FILE`.
+- Adjusted `.gitignore` to track standard Python and Node virtual environment directories properly.
+
+### Fixed
+- Fixed uninitialized class name alias by swapping `Graph` to `NavigationGraph` across references.
+- Remedied route step structure by moving away from hardcoded dataclass references (`RouteStep`) to generic dictionaries in `backend/src/route.py`.
+- Checked and resolved printing of `snipe` variable references within `backend/src/manager.py` loops arrays versus strings.
