Execute '*': add execute-all GitHub Actions workflow

[Copilot]

Adds a workflow that implements the * operator — executing all repository operations in a single run.

Description

New .github/workflows/execute.yml triggers make all (init → install → test → validate) on push/PR to main and via workflow_dispatch.

name: Execute *
on:
  push:
    branches: [ main, copilot/** ]
  pull_request:
    branches: [ main ]
  workflow_dispatch:
jobs:
  execute-all:
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with: { node-version: '20' }
      - run: make all

Checklist

• My code follows the style guidelines of this project

• My changes generate no new warnings

Additional Notes

Consistent with existing ci.yml patterns. The all: Makefile target was already defined; this workflow surfaces it as a named, triggerable action.

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/repos/professoroakz/.github/commits/36daaab
  • Triggering command: /usr/bin/curl curl -s REDACTED -H Accept: application/vnd.github.diff (http block)
• https://api.github.com/repos/professoroakz/.github/commits/542c110
  • Triggering command: /usr/bin/curl curl -s REDACTED -H Accept: application/vnd.github.diff (http block)
• https://api.github.com/repos/professoroakz/.github/git/blobs/c5948262032cf0935fca77d989f812ced7a4dab3
  • Triggering command: /usr/bin/curl curl -s REDACTED (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)
