CHANGELOG.md

Added v0.1.5 section documenting:

• New Feature: Public Pool.add_task() API (was _add_task())
• Type Safety: Generic type parameters on TaskHandler protocols (ContextT, ResultT)
• Improvements: Optional activity percentage field, config extra="ignore"
• Bug Fixes: Database URL rendering, missing db.commit() in tracker
• Testing: New test_task_types.py for protocol validation

# Now public API for programmatic task registration
pool.add_task("research", research_handler)

# Better type inference for handlers
async def handler(*, agent_id: UUID, context: MyContext) -> MyResult:
    ...  # ContextT and ResultT properly inferred
