[schema-coverage] feat: Add schema coverage demo for labels field

[github-actions]

Schema Coverage Demo

This PR adds a minimal demo workflow that demonstrates usage of the labels field in the gh-aw frontmatter schema.

Why: The schema feature coverage checker found that labels was not used in any existing workflow.

What: Adds schema-demos/schema-demo-labels.md with a valid, minimal demonstration of this field.

Field Description

Optional array of labels to categorize and organize workflows. Labels can be used to filter workflows in status/list commands.

Validation

Attempted make agent-finish, but it was blocked before tests by the Go toolchain download: proxy.golang.org returned Forbidden for golang.org/toolchain@v0.0.1-go1.25.8.linux-amd64.zip. No local ./gh-aw binary was present for compile-only validation.

Warning

Firewall blocked 3 domains

The following domains were blocked by the firewall during workflow execution:

• ab.chatgpt.com
• chatgpt.com
• proxy.golang.org

To allow these domains, add them to the network.allowed list in your workflow frontmatter:

network:
  allowed:
    - defaults
    - "ab.chatgpt.com"
    - "chatgpt.com"
    - "proxy.golang.org"

See Network Configuration for more information.
