APT Repository Update Workflow

[mairas]

Create workflow to automatically notify APT repository when a release is published (adapted from HALPI2-firmware).

Implementation details:

Create .github/workflows/release-published.yml (adapted from HALPI2-firmware/release.yml):

Trigger: Release published (not draft, not pre-release)

Actions:

• Extract version from release tag (strip leading 'v')
• Trigger repository dispatch to apt.hatlabs.fi repository
• Send payload with package name, version, and source repository

Required Secret:

• APT_REPO_PAT - Personal Access Token with repo dispatch permissions

Workflow:

on:
  release:
    types: [published]

jobs:
  notify-apt-repo:
    - Extract version from tag
    - Trigger repository dispatch
      - Repository: hatlabs/apt.hatlabs.fi
      - Event type: package-updated
      - Payload: {package: "halpid", version: "<version>", repository: "<repo>"}

Test scenarios:

• Publishing a draft release triggers APT repo update
• Version is correctly extracted from tag (v5.0.0 -> 5.0.0)
• Repository dispatch is sent successfully
• APT repo receives and processes the notification

Acceptance criteria:

• Workflow file created and committed
• Triggers only on published releases (not drafts/pre-releases)
• Version extraction works correctly
• Repository dispatch configured correctly
• APT_REPO_PAT secret configured in repository settings
• Workflow adapted from HALPI2-firmware/release.yml

Caveats:

• Requires PAT secret configured in repository settings
• PAT must have repo scope for repository dispatch
• APT repository must be configured to handle package-updated events
• Only triggers on published releases, not when editing release notes

Dependencies:

• Release Workflow and Debian Package Build #34 (draft release workflow)
• APT repository infrastructure must be set up
