Rename MainLoop to AgentLoop throughout codebase

[andreisavu]

Summary

This PR renames all references to MainLoop to AgentLoop across the trivia agent codebase to align with the updated WINK framework terminology. This includes renaming the main entry point file from worker.py to agent_loop.py and updating all imports, type hints, and documentation.

Key Changes

• File rename: src/trivia_agent/worker.py → src/trivia_agent/agent_loop.py
• Class rename: MainLoop → AgentLoop in all type hints and base classes
• Type renames:
  • MainLoopRequest → AgentLoopRequest
  • MainLoopResult → AgentLoopResult
  • MainLoopConfig → AgentLoopConfig
• Import updates: Updated all imports from weakincentives.runtime to use the new AgentLoop* types
• Script entry point: Updated pyproject.toml to point trivia-agent command to agent_loop:main
• Documentation: Updated all docstrings, comments, and README references from "MainLoop" to "AgentLoop"
• Test file rename: tests/trivia_agent/test_worker.py → tests/trivia_agent/test_agent_loop.py
• Dependency update: Bumped weakincentives from v0.23.0 to v0.24.0 to support the new naming

Files Modified

• Core agent loop: src/trivia_agent/agent_loop.py (renamed from worker.py)
• Configuration and setup: pyproject.toml
• Mailbox definitions: src/trivia_agent/mailboxes.py
• Dispatch logic: src/trivia_agent/dispatch.py
• Evaluation loop: src/trivia_agent/eval_loop.py
• Adapters, feedback, isolation, and sections modules: Updated documentation
• Tests: Renamed test file and updated all patch paths and imports
• Documentation: AGENTS.md and README.md

Notes

• All functionality remains unchanged; this is purely a naming/terminology update
• The rename improves clarity by using "AgentLoop" to describe the production request processing loop
• All imports have been reorganized to maintain consistency (e.g., in eval_loop.py and test files)
