Julian Pawlowski 503075c443 refactor(config_flow): restructure package to satisfy hassfest validation
Home Assistant's hassfest validation requires config flows to be defined
in a file named config_flow.py (not a package directory).

Changes:
- Renamed custom_components/tibber_prices/config_flow/ → config_flow_handlers/
- Created config_flow.py as bridge file re-exporting from config_flow_handlers/
- Updated all import paths across 5 files (user_flow, options_flow, subentry_flow, etc.)
- Added ./scripts/hassfest for local validation (JSON/Python syntax, required files)
- Added ./scripts/clean with three modes (--minimal, normal, --deep)
- Refactored develop/lint/lint-check to use centralized cleanup (DRY principle)
- Updated documentation in AGENTS.md and docs/development/

Technical details:
- Bridge file uses __all__ exports to maintain clean public API
- hassfest script uses ast.parse() for syntax validation (no disk artifacts)
- clean --minimal removes .egg-info only (silent, for automated scripts)
- Dual pip/uv pip compatibility for package uninstallation

Impact: Integration now passes hassfest validation. Local validation available
via ./scripts/hassfest before pushing to GitHub. Cleanup logic centralized and
DRY across all development scripts.

Coding Guidelines

Note: For complete coding standards, see AGENTS.md.

Code Style

  • Formatter/Linter: Ruff (replaces Black, Flake8, isort)
  • Max line length: 120 characters
  • Max complexity: 25 (McCabe)
  • Target: Python 3.13

Run before committing:

./scripts/lint        # Auto-fix issues
./scripts/hassfest    # Validate integration structure

Import Order

  1. Python stdlib (specific types only)
  2. Third-party (homeassistant.*, aiohttp)
  3. Local (.api, .const)

Critical Patterns

Time Handling

Always use dt_util from homeassistant.util:

from homeassistant.util import dt as dt_util

price_time = dt_util.parse_datetime(starts_at)
price_time = dt_util.as_local(price_time)  # Convert to HA timezone
now = dt_util.now()

Translation Loading

# In __init__.py async_setup_entry:
await async_load_translations(hass, "en")
await async_load_standard_translations(hass, "en")

Price Data Enrichment

Always enrich raw API data:

from .price_utils import enrich_price_info_with_differences

enriched = enrich_price_info_with_differences(
    price_info_data,
    thresholds,
)

See AGENTS.md for complete guidelines.
