Problem

The release workflow has been failing since October 23rd with the following error:

##[error]Invalid value. Matching delimiter not found 'ghadelimiter_c62aa20a-2e80-4e1f-9492-de0ef078d1a2'

This issue was introduced by recent attempts (PRs #15 and #17) to use heredoc syntax with a uuidgen-generated delimiter for handling multiline content in the "Read release.md and use it as a body of new release" step. While the heredoc approach aimed to properly handle multiline content, it wasn't being correctly recognized by GitHub Actions, causing all subsequent workflow runs to fail.

Solution

This PR reverts the problematic step (lines 76-84 in .github/workflows/release.yml) back to the escape sequence approach that was working successfully before. The workflow is now identical to commit 0fe48b9 from October 23rd, which had multiple successful runs.

Changed from heredoc approach:

delimiter="ghadelimiter_$(uuidgen)"
echo "RELEASE_BODY<<${delimiter}" >> $GITHUB_OUTPUT
cat ./chaiNNer/history.txt >> $GITHUB_OUTPUT
echo "${delimiter}" >> $GITHUB_OUTPUT

Back to escape sequence approach:

r=$(cat ./chaiNNer/history.txt)
r="${r//'%'/'%25'}"                               # Multiline escape sequences for %
r="${r//$'\n'/'%0A'}"                             # Multiline escape sequences for '\n'
r="${r//$'\r'/'%0D'}"                             # Multiline escape sequences for '\r'
echo "RELEASE_BODY=$r" >> $GITHUB_OUTPUT

The escape sequence method is the recommended approach for handling multiline strings in GitHub Actions outputs and has been proven to work reliably in this workflow's history.

Verification

• ✅ YAML syntax validated
• ✅ No diff between current version and last working version (0fe48b9)
• ✅ Code review passed
• ✅ CodeQL security scan: 0 alerts

This restores the release workflow to a known working state as requested in issue #18.

• Fixes Workflows broken #18
