🔵 Needs a closer look

The newly added config files contain trailing whitespace that will immediately trigger the configured trailing-whitespace hook and cause pre-commit runs to fail until corrected.

Pull request overview

Restores local developer validation by introducing a pre-commit configuration for Go formatting/build/test/lint and adding a markdownlint configuration to standardize Markdown checks.

Changes:

• Adds .pre-commit-config.yaml with local Go hooks plus markdownlint, codespell, and common pre-commit hygiene checks.
• Adds .markdownlint.yaml to enable markdownlint defaults while disabling MD013 (line length).

.pre-commit-config.yaml:77

• There is trailing whitespace on the final line (line 77). With the trailing-whitespace pre-commit hook enabled in this same config, this file will be auto-modified and cause the hook run to fail until re-staged.

.markdownlint.yaml:4

• Line 4 contains trailing whitespace (a blank line with spaces). This will be caught by the trailing-whitespace pre-commit hook and cause the hook run to fail until the whitespace is removed.

MD013: false
