[BUG] prepare-release changelog commits silently skipped due to FILE_PATHS delimiter mismatch

[c-vigo]

Description

The prepare-release.yml workflow passes FILE_PATHS as space-separated values to vig-os/commit-action@v0.2.0, but the action splits on commas. The entire space-separated string is treated as a single non-existent path, silently skipped, and both commit steps succeed with "No files to commit" instead of creating the expected commits.

The prepare-release workflow is designed to:

1. Freeze the CHANGELOG on dev (Unreleased → [X.Y.Z] - TBD + fresh empty Unreleased), commit to dev
2. Create the release branch from dev (post-freeze)
3. Strip the empty Unreleased section from the release branch, commit to release/X.Y.Z

All commits use commit-action to bypass branch protection rulesets via GitHub App token.

Because both commit steps silently no-op, the release branch is created from the unfrozen dev SHA, and neither branch receives the expected changelog modifications.

Steps to Reproduce

1. Trigger the "Prepare Release" workflow with version 0.3.2
2. Both "Commit prepared CHANGELOG to dev via API" and "Commit stripped CHANGELOG to release branch via API" log "No files to commit"
3. Workflow reports success despite no commits being created

Evidence: Run #23899040367, job Prepare Release Branch

Expected Behavior

commit-action should commit both CHANGELOG.md and assets/workspace/.devcontainer/CHANGELOG.md to the target branches with the frozen/stripped content.

Actual Behavior

commit-action receives FILE_PATHS="CHANGELOG.md assets/workspace/.devcontainer/CHANGELOG.md", splits on ,, gets a single path "CHANGELOG.md assets/workspace/.devcontainer/CHANGELOG.md" which doesn't exist, silently skips it, and returns "No files to commit" with exit code 0.

Environment

• GitHub Actions, ubuntu-22.04 runner
• vig-os/commit-action@1bc004353d08d9332a0cb54920b148256220c8e0 (v0.2.0)
• Workflow: .github/workflows/prepare-release.yml

Possible Solution

Change both FILE_PATHS values in prepare-release.yml from space-separated to comma-separated:

# Before
FILE_PATHS: CHANGELOG.md assets/workspace/.devcontainer/CHANGELOG.md
# After
FILE_PATHS: CHANGELOG.md,assets/workspace/.devcontainer/CHANGELOG.md
