Add automated winget package submission

[Copilot]

Automates submission of semver-cli releases to the Windows Package Manager (winget) repository.

Changes

Publish workflow (.github/workflows/publish.yml):

• Added ZIP artifact creation for Windows builds (winget requirement)
• New winget job on windows-latest runner that:
  • Generates three manifest files (installer, locale, version) following winget 1.6.0 schema
  • Uses portable installer type with nested semver.exe
  • Validates manifests via winget validate
  • Creates PR to microsoft/winget-pkgs repository
• Manifest directory structure: manifests/o/Optum/semver/{VERSION}/
• SHA256 hash extracted via PowerShell, normalized to lowercase
• Release date sourced from GitHub event metadata

Documentation (README.md):

• Added winget installation section with package identifier Optum.semver

Behavior

Triggers on release publish (non-prerelease only). After assets build completes, generates manifests and submits PR to microsoft/winget-pkgs for review. Users can install via winget install Optum.semver after Microsoft approval.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/microsoft/winget-pkgs
  • Triggering command: /usr/bin/curl curl -s REDACTED (http block)
• https://api.github.com/repos/microsoft/winget-pkgs/git/trees/master
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (http block)
• learn.microsoft.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
