Add GitKraken Merge Mate workflows

[Copilot]

Implements GitKraken Merge Mate for automated PR syncing and AI-powered conflict resolution.

Workflows Added

• merge-mate.yml - Triggers on main branch pushes, syncs all open PRs using GitKraken AI provider
• merge-mate-review.yml - Handles apply/undo via PR checkbox edits or manual workflow_dispatch, includes concurrency control per PR

Configuration

Both workflows reference secrets.GK_AI_PROVISIONER_TOKEN (needs to be added) and require the GitKraken Services GitHub App installation.

Permissions: contents: write, pull-requests: write, id-token: write

Action version: @v0.1 (pre-release)
