…es (#299)

## Description

Fixed shellcheck warnings SC2086 (unquoted variables) and SC2129
(ungrouped redirects) in GitHub Actions workflow files. These warnings
were surfaced during CI runs and follow the same fix patterns
established in PR #246.

- Quoted `$GITHUB_ENV` and `$GITHUB_STEP_SUMMARY` shell variables to
prevent word splitting
- Grouped multiple `echo` statements into single redirects using brace
syntax `{ ...; } >> file`
- Applied fixes to both `markdown-lint.yml` and `codeql-analysis.yml`
workflows
