Add estimate, aggregate, modify, and batch API endpoints

[arauhala]

Summary

• Add estimate() function for numeric value estimation using K-NN
• Add aggregate() function for aggregated values (sum, avg, count, etc.)
• Add modify() function for atomic data modifications with helper classes:
  • Insert: insert single or multiple entries
  • Update: update entries with fluent where().set().upsert() interface
  • Delete: delete entries matching a condition
• Add batch() function for executing multiple queries in a single HTTP request
• Add corresponding request/response classes for all new endpoints
• Bump version to 0.5.2

Example usage

import aito.api as api
from aito.client.requests import Insert, Update, Delete

# Estimate numeric values
result = api.estimate(client, {
    "from": "products",
    "where": {"name": "rye bread"},
    "estimate": "price"
})

# Batch multiple queries
results = api.batch(client, [
    {"from": "products", "predict": "category", "where": {"name": "bread"}},
    {"from": "products", "similarity": {"name": "bread"}}
])

# Modify data with helper classes
api.modify(client, Insert("products", {"id": "1", "name": "Apple"}))
api.modify(client, Update("products").where({"id": "1"}).set({"name": "New Name"}))
api.modify(client, Delete("products", {"id": "1"}))

# Multiple atomic operations
api.modify(client, [
    Insert("products", {"id": "1", "name": "Apple"}),
    Update("products").where({"id": "2"}).set({"name": "Banana"})
])

Test plan

• All existing SDK tests pass (193 tests)
• Estimate endpoint tested with grocery demo
• Batch endpoint tested with grocery demo
• Modify helpers tested (Insert, Update, Delete)
• Multiple modify operations tested
