Add remove-labels safe output

[Copilot]

Adds a remove-labels safe output that allows agentic workflows to remove labels from issues and pull requests. This complements the existing add-labels safe output.

Changes

• Go implementation (pkg/workflow/remove_labels.go): Config struct and parsing logic following add-labels pattern
• JavaScript handler (actions/setup/js/remove_labels.cjs): Processes remove_labels messages, gracefully skips labels not present on the item
• Schema updates: Added to main_workflow_schema.json and safe_outputs_tools.json
• Wiring: Updated config generation, handler registration, permissions, imports merging, and TypeScript types

Usage

safe-outputs:
  remove-labels:
    allowed:
      - needs-triage
      - bug
    max: 5
    target: triggering  # or "*" or explicit number

Supports same options as add-labels: max, allowed, target, target-repo, github-token.

Original prompt

Do we have a remove-label safe output? Please first check whether something like this already exists (doesn't have to have that specific name, just looking for a safe output that removes a label from an issue or PR). If it doesn't please implement it.
