Fix whitespace formatting errors (W291, W292, W293)

[Copilot]

Resolves ruff/flake8 whitespace violations causing Code Quality Checks workflow failures: trailing whitespace on lines (W291), blank lines with whitespace (W293), and missing newlines at EOF (W292).

Changes

• Removed trailing whitespace from 128 locations across 7 files
• Added missing EOF newlines
• Applied black and isort formatting to maintain consistency with existing code quality standards

Files Modified

• scrapegraphai/utils/code_error_analysis.py
• scrapegraphai/utils/code_error_correction.py
• scrapegraphai/utils/research_web.py
• scrapegraphai/graphs/markdownify_graph.py
• scrapegraphai/helpers/models_tokens.py
• scrapegraphai/models/xai.py
• scrapegraphai/nodes/markdownify_node.py

All modified files now pass ruff, black, and isort checks. Pre-existing E402 errors in unrelated files remain unchanged.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• astral.sh
  • Triggering command: /usr/bin/curl curl -LsSf REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

The 'Code Quality Checks' workflow fails due to multiple whitespace formatting errors, specifically:

• W293: Blank line contains whitespace
• W292: No newline at end of file
• W291: Trailing whitespace

To fix:

• Remove trailing whitespace characters from all blank lines in affected files.
• Ensure every file ends with a single newline (\n) character.
• Remove trailing whitespace from the end of all lines.

This will address all ruff/flake8 complaints seen in the failing CI run (see: https://github.com/ScrapeGraphAI/Scrapegraph-ai/actions/runs/19911826024) and allow the workflow to pass.

Examples of affected files/lines from the latest failure:

• scrapegraphai/utils/code_error_analysis.py (lines: 83, 86, 109, 160, 214, 271)
• scrapegraphai/utils/code_error_correction.py (lines: 63, 66, 290)
• scrapegraphai/utils/research_web.py (lines: 249, 290, 387)

You may use ruff --fix . or autopep8 --in-place --aggressive --aggressive -r . for bulk correction, or clean manually.

After fixing, verify the 'Code Quality Checks' workflow passes.
