Suppress linter errors via ruff configuration to re-enable CI checks

[Copilot]

• Analyze all linter errors to identify error codes
• Add ruff configuration to pyproject.toml to suppress all current errors
• Verify that hatch fmt --check passes with the new configuration
• Update CI workflow to re-enable the linter check
• Fix CI to only check linting (not formatting) using --linter flag

<issue_title>Fix linter errors</issue_title>
<issue_description>I switched off the linter because it produces 100s of error messages:

seclab-taskflow-agent/.github/workflows/ci.yml

Line 38 in d4d4acd

# hatch fmt --check

We should fix those errors (or find a way to suppress them if they're uninteresting), so that we can switch the check on.</issue_description>

<agent_instructions>Add a ruff configuration to suppress all current linter errors. I want this to be a small PR, so do not attempt to fix any of the errors, just suppress them.</agent_instructions>

Fixed in c2b6dca. The issue was that hatch fmt --check runs both linter and formatter checks. The linter now passes but files need reformatting. Changed CI to use --linter flag to only check linting, not formatting.

Pull request overview

This PR addresses issue #83 by configuring ruff to suppress all existing linter errors and re-enabling the linter check in CI. Rather than fixing hundreds of linter errors, this establishes a baseline by ignoring current violations, allowing the linter to catch new issues going forward.

Changes:

• Added comprehensive ruff configuration to pyproject.toml with 81 suppressed error codes
• Re-enabled linter check in CI workflow using hatch fmt --linter --check
