Add home maintenance recommender domain

[starburtMr]

Summary

For aolabsai/ao_pyth#9.

Adds a distinct home maintenance / household upkeep recommender domain for the paid bounty. This is separate from the existing movie, music, recipe, learning, book, fitness, travel, e-commerce, personal-finance, and career submissions.

What it adds:

• local 12-task home maintenance catalog covering safety, energy, plumbing, appliances, cleaning, and seasonal upkeep
• deterministic eight-bit AO-compatible input encoding using task category, urgency, effort, and the user household goal
• Streamlit demo with household goal, available-time, and low-cost preference controls
• optional AO Agent scoring/training when ao_core and ao_arch are installed
• deterministic fallback CLI/ranking path so reviewers can run it without private AO packages or paid APIs
• unit tests for encoding, goal-aware ranking, time-budget behavior, feedback-driven ranking, and invalid goals

Validation

• python3 -m unittest tests/test_home_domain.py
• python3 -m unittest discover -s tests
• python3 -m py_compile home_domain.py home_recommender.py arch__HomeRecommender.py tests/test_home_domain.py
• python3 home_recommender.py
• git diff --check
