ci: Add Chocolatey and Winget publish workflows

[rianjs]

Summary

Add GitHub Actions workflows for publishing to Chocolatey and Winget package managers, following the established patterns in google-readonly and atlassian-cli.

Files to Create

Publish Workflows

• .github/workflows/chocolatey-publish.yml - Manual workflow to publish to Chocolatey
• .github/workflows/winget-publish.yml - Manual workflow to publish to Winget

Test Workflows

• .github/workflows/test-chocolatey.yml - CI workflow to validate Chocolatey packaging on PR/push
• .github/workflows/test-winget.yml - CI workflow to validate Winget manifests on PR/push

Implementation Notes

Reference implementations:

• google-readonly/.github/workflows/chocolatey-publish.yml
• google-readonly/.github/workflows/winget-publish.yml
• google-readonly/.github/workflows/test-chocolatey.yml
• google-readonly/.github/workflows/test-winget.yml

Key patterns:

• Publish workflows are workflow_dispatch triggered with version input
• Test workflows trigger on packaging/** path changes
• Chocolatey uses choco pack and choco push
• Winget uses wingetcreate to submit to microsoft/winget-pkgs

Required Secrets

• CHOCOLATEY_API_KEY - API key for pushing to chocolatey.org
• WINGET_GITHUB_TOKEN - GitHub PAT for creating PRs to winget-pkgs

Existing Files

The packaging structure already exists:

• packaging/chocolatey/hubspot-cli.nuspec
• packaging/chocolatey/tools/
• packaging/winget/OpenCLICollective.hubspot-cli.yaml
• packaging/winget/OpenCLICollective.hubspot-cli.installer.yaml
• packaging/winget/OpenCLICollective.hubspot-cli.locale.en-US.yaml
