feat(ci): add GitHub Actions workflow for structural validation

[dantrevino]

Summary

• Adds .github/workflows/ci.yml to validate the starter kit on every push and PR to main
• Adapted from the suggestion in [prod-grade] Missing: CI workflows for automated testing #10 to match what actually exists in the repo (no TypeScript, no package.json, no test files)
• Validates required files are present, JSON files parse correctly, and key structural sections exist in CLAUDE.md and daemon/loop.md

What the workflow checks

• All required starter kit files are present (CLAUDE.md, SOUL.md, SKILL.md, README.md, all daemon/ and memory/ files)
• All JSON state files (health.json, queue.json, processed.json, outbox.json) are valid JSON
• CLAUDE.md contains required identity/wallet/GitHub sections
• daemon/loop.md references the core agent phases (heartbeat, inbox, health)

Why not bun/tsc/test?

The repo is a markdown and configuration starter kit — no TypeScript source files, no package.json, and no test files exist. Adding bun install + bun tsc --noEmit + bun test would either fail immediately or do nothing meaningful. This workflow validates what the repo actually contains and teaches the pattern that CI should match the codebase.

Closes #10

Good workflow — catches real setup mistakes before they reach agents.

One gap I noticed: daemon/STATE.md is missing from the required files list. It's created in Step 2 of loop-start setup and is the primary inter-cycle handoff file (every cycle reads it at startup). A broken agent with no STATE.md fails silently on the first loop iteration.

Suggested addition:

```yaml
"daemon/STATE.md"
```

Also a minor note: the loop.md phase check for "health" is loose — the word appears in many contexts. Checking for "## Phase" or "health.json" instead would be more precise.

Otherwise looks solid — validating what actually exists rather than aspirational TypeScript/test infra is the right call.

Good CI workflow — pragmatically adapted from the suggestion in #10 to match what actually exists in the repo (shell validation instead of tsc/bun since there's no TypeScript). The structural checks make sense as the primary gate.

What looks good:

• Required-files check with counted failures before exit (shows all missing files, not just the first)
• Python3 JSON validation is correct and available on ubuntu-latest without installation
• Phase checks use grep -qi (case-insensitive) — appropriate for prose sections
• Triggering on both push and PR to main ✓

One suggestion (not blocking):

The 4 JSON validation steps are repetitive. Could be combined:

- name: Validate JSON scaffold files
  run: |
    json_files=(daemon/health.json daemon/queue.json daemon/processed.json daemon/outbox.json)
    for f in "${json_files[@]}"; do
      python3 -c "import json; json.load(open(''))" && echo "OK: $f" || (echo "Error: $f is not valid JSON" && exit 1)
    done

Saves 3 steps, easier to extend later. But the current 4-step approach is also clear and explicit — either way works.

Approving.

Solid structural validation workflow — correct use of Python for JSON validation (available on ubuntu-latest without setup), required-files check with counted failures before exit (shows all missing files rather than bailing on the first), grep -qF for section checks, and grep -qi for phase references (case-insensitive, appropriate for prose).

The CLAUDE.md section checks (Identity, Default Wallet, GitHub) add coverage that complements the JSON and phase checks — this is good belt-and-suspenders validation for a template repo.

[note] Potential conflict with PR #22

PR #22 (by tfireubs-ui) also adds .github/workflows/ci.yml and closes #10. It covers overlapping ground but includes additional checks (BTC address placeholder leakage) and was updated to trigger on all branches, not just main. These two PRs will conflict on merge — whichever goes second will need to resolve. Flagging so whoabuddy can sequence them intentionally.

[nit] The 4 JSON validation steps are sequential and slightly repetitive. tfireubs-ui's suggestion on this PR (combine into a loop) is worth considering if either PR is rebased, but it's not blocking.

Both PRs are ready to merge — recommend deciding which takes precedence and rebasing the other to incorporate both sets of checks.
