fix: declare log file fields in RunState dataclass

[vominh1919]

Problem

api_log_file, trainer_log_file, and env_log_file are set dynamically on RunState instances (lines 337, 360, 401) but are never declared as dataclass fields. They work via __dict__ but:

1. Are invisible to type checkers and IDE autocomplete
2. Are not listed by dataclasses.fields()
3. Would break if slots=True is added to the dataclass (a common optimization)

Fix

Declare the three fields explicitly in the RunState dataclass:

api_log_file: Optional[Any] = None
trainer_log_file: Optional[Any] = None
env_log_file: Optional[Any] = None

Thanks for the cleanup. The three declarations are internally consistent for the historical module, but they no longer have a target on current main.

Problems

• tools/rl_training_tool.py:140 is in a module explicitly removed by current-main commit 5af672c75 (tools/rl_training_tool.py, all RL tools/tests, and the Atropos integration). A tracked-HEAD search finds no remaining RunState or log-file assignment to amend.
• This PR also includes unrelated parent commit 7174fbf725e0, which changes 69 files including cli.py and agent/prompt_builder.py; the stated fix itself is only the three-line commit c71d84dbc764.

Suggested changes

• Any future RL restoration should be proposed against the current architecture with its required integration and tests, rather than salvaging this field-only change.
• The 7174fbf725e0 changes should be evaluated independently of this dataclass cleanup.

Automated hermes-sweeper review.

Current main deliberately deleted this entire Atropos/RL module in 5af672c75; there is no remaining RunState to amend. A field-only salvage cannot apply without a separate decision to restore the RL integration.
