Add Azure DevOps automated release pipeline

[Copilot]

Automate releases by bumping the version in package.json, building distributable files, committing the change back to the branch, and publishing the artifact — all from a single pipeline run.

Pipeline (azure-pipelines.yml)

• Trigger: pushes to master; pr: none to skip PR builds
• Version bump: uses npm version --git-tag-version=false; strips the v prefix so the stored variable matches the semver format in package.json
• Build: runs npx gulp build to produce dist/
• Commit & tag: does a --rebase pull before pushing to reduce race conditions on concurrent runs; commits with [skip ci] to avoid re-triggering; creates a vX.Y.Z tag
• Artifact: publishes dist/ as a named build artifact consumable by downstream release stages

Controlling the bump type

Override the versionBump variable at queue time:

patch  (default)  2.0.3 → 2.0.4
minor             2.0.3 → 2.1.0
major             2.0.3 → 3.0.0
