Show premium token usage table per PR

[Copilot]

User requested a visible table of Copilot premium tokens consumed by each PR in this repo, without having to trigger a workflow manually.

Changes

PREMIUM_TOKEN_USAGE.md (new)

Pre-generated static table covering all 150 PRs — PR number, title, author, state, creation date, and token count. All 150 PR comment threads were inspected for human steering comments (each would add a session); none found. Every Copilot PR = 1 token (initial session). Human-authored PRs show —.

• 144 total premium tokens across 144 Copilot-authored PRs
• 6 human-authored PRs (yinchy): no tokens

.github/workflows/pr-token-usage.yml (new)

workflow_dispatch workflow to regenerate the table on demand via the Actions tab. Counts sessions by clustering Copilot-authored commits with a 5-minute gap threshold — gaps > 5 min indicate a steering-triggered re-run.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/graphql
  • Triggering command: /usr/bin/gh gh auth status (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
