feat: add dry run support for release process

[Copilot]

Implementation Complete: Dry Run Support for Release Process

Successfully implemented dry run support for the Wassette release process. Tags with hyphen suffixes (e.g., v0.3.4-test1) are treated as prereleases and skip CHANGELOG/manifest updates.

✅ All Tasks Completed:

• Detect prerelease tags in release.yml workflow
• Update release job to mark prereleases appropriately
• Update update-changelog job condition to skip prereleases
• Update update-package-manifests to skip prereleases
• Update RELEASE.md documentation with dry run instructions
• Update CHANGELOG.md with new feature
• Test prerelease detection logic
• Verify all tests pass
• Address review feedback: simplify documentation and move CHANGELOG entry

Changes Summary:

.github/workflows/release.yml (16 additions, 3 deletions):

• Added prerelease detection logic in version extraction step
• Set prerelease: true for tags containing hyphen
• Added condition to skip update-changelog job for prerelease tags

.github/workflows/update-package-manifests.yml (2 additions):

• Added condition to skip job for prerelease releases

RELEASE.md (simplified documentation):

• Added "Dry Run / Test Releases" section
• Simplified explanation: concisely states it skips CHANGELOG and manifest updates
• Provided examples and cleanup instructions

CHANGELOG.md (moved to Changed section):

• Moved entry from "Added" to "Changed" section as change fragment
• Documents the new dry run feature

How It Works:

For regular releases (e.g., v0.4.0):

• ✅ Builds binaries for all platforms
• ✅ Creates GitHub release as stable
• ✅ Updates CHANGELOG with version and date
• ✅ Updates package manifests (Homebrew, WinGet)

For dry run releases (e.g., v0.3.4-test1):

• ✅ Builds binaries for all platforms
• ✅ Creates GitHub release marked as "Pre-release"
• ❌ Skips CHANGELOG update
• ❌ Skips package manifest updates

Tag Detection Logic:

if [[ "$VERSION" == *-* ]]; then
  is_prerelease=true  # Skip CHANGELOG/manifests
else
  is_prerelease=false  # Full release process
fi

Supported Prerelease Patterns:

• Test releases: v0.3.4-test1, v0.3.4-test2
• Release candidates: v0.4.0-rc1, v0.4.0-rc2
• Alpha/Beta: v0.4.0-alpha, v0.4.0-beta
• Hotfix tests: v0.3.4-hotfix-test

Testing & Validation:

1. ✅ Prerelease detection logic tested with 11 tag formats
2. ✅ All existing changelog_utils.py tests pass (11/11)
3. ✅ YAML syntax validated for both workflow files
4. ✅ Code compiles successfully with cargo check
5. ✅ No breaking changes to existing functionality

Usage Example:

# Create and push prerelease tag
git tag -s v0.3.4-test1 -m "Test release v0.3.4-test1"
git push origin v0.3.4-test1

# Result: Binaries published, no CHANGELOG/manifest updates

Benefits:

• Safe Testing: Test release pipeline without affecting production
• Release Candidates: Create RC versions for validation
• No Manual Cleanup: CHANGELOG/manifests don't need reverting
• Clear Separation: Prereleases visibly marked on GitHub
• Backward Compatible: Regular releases unchanged

Original prompt

the release process should support a dry run (such as releasing v0.3.4-test1) and this process can push the built binary to github release page, but do not update changelog or trigger update-package-manifests

@copilot please fix the comment, also delete the section on what happens during a dry run and concisely just say it will skip changelog update and skip package manifest updates

Fixed in commit 1d40148. Deleted the "What Happens During a Dry Run" section and replaced it with a single concise sentence stating it skips CHANGELOG updates and package manifest updates.
