Extract Autoloop scheduler from inline heredoc into a committed Python script

[Copilot]

The ~470-line inline node - << 'JSEOF' scheduler in workflows/autoloop.md is approaching GitHub Actions' compiled run: expression size limit, and is unreachable to linters, type-checkers, and unit tests. Sibling proposals add ~30–60 LOC each to the scheduler — extraction is a prerequisite.

Changes

• New workflows/scripts/autoloop_scheduler.py — stdlib-only Python (os, re, json, glob, urllib, datetime) with named, importable helpers: parse_machine_state, parse_schedule, parse_program_frontmatter, is_unconfigured, check_skip_conditions, select_program, slugify_issue_title, parse_link_header, plus a main() entry point.
• Workflow shrinks — workflows/autoloop.md "Check which programs are due" step is now a one-liner; lock file and dogfooded .github/workflows/autoloop.md updated in lockstep, and a byte-identical copy of the script lives at .github/workflows/scripts/ so the install copy step (cp -r workflows/ .github/workflows/) needs no change.
• Tests rewired — tests/conftest.py imports the script directly via importlib (replacing JS-extraction-via-Node.js subprocess). Existing 100 tests in test_scheduling.py preserved via thin shims for shape differences.
• New tests/test_scheduler_e2e.py — 9 fixture-based subprocess tests exercising main(): more-overdue selection, never-run priority, missing state file → first run, paused/completed → skipped, AUTOLOOP_PROGRAM=<name> forced bypass (incl. forcing a paused program), unknown forced name → error, no programs found.
• AGENTS.md documents the new workflows/scripts/ directory in the repo layout and deployment steps.

  - name: Check which programs are due
    env:
      GITHUB_TOKEN: ${{ github.token }}
      GITHUB_REPOSITORY: ${{ github.repository }}
      AUTOLOOP_PROGRAM: ${{ github.event.inputs.program }}
    run: |
      python3 .github/workflows/scripts/autoloop_scheduler.py

Net diff: workflows/autoloop.md 1179 → 717 lines; .github/workflows/autoloop.md 837 → 694 lines; lock file's inline scheduler collapses to one shell line. 109/109 tests pass; CodeQL clean.

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:

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)

@copilot fix failing tests

Fixed in 53ce1c2 — CI was missing pyyaml, which the pre-existing test_lock_creds_before_merge test imports. Added it to the pip install step in .github/workflows/tests.yml.
