[Bug]: CI is broken on main (lint, framework tests, tools tests)

[Hundao]

Describe the Bug

All CI checks on main are currently failing: Lint Python, Test Python Framework, and Test Tools. This has been the case for at least several days (last 5 CI runs on main all fail).

To Reproduce

1. Check any recent CI run on main
2. All three jobs fail: Lint Python (155 ruff errors), Test Python Framework (multiple test failures), Test Tools

Expected Behavior

CI on main should be green.

Environment

• CI: GitHub Actions (ubuntu-latest)
• Python version: 3.11
• ruff: 0.15.0

Logs

Lint: Found 155 errors. [*] 69 fixable with the --fix option

Framework test failures include: test_colony_runtime_overseer, test_default_skills, test_event_loop_node, and others.

Additional Context

Plan to fix in multiple PRs to keep changes reviewable:

1. Lint + format (ruff check + ruff format)
2. Framework test failures (TBD)
3. Tools test failures (TBD)
