Add project guidelines verification script

Created comprehensive verification script to check codebase against PROJECT_GUIDELINES.md

Features:
- Checks for custom CSS (TailwindCSS requirement)
- Detects JavaScript files that should be TypeScript
- Verifies no secrets committed (.env, credentials.json)
- Validates code compiles (go build)
- Finds local binaries (should use container builds)
- Quick checks with clear pass/fail/warning output

Usage:
  make verify-guidelines
  ./scripts/verify-quick.sh

Current codebase status:
  - 12 templates with custom CSS (need Tailwind conversion)
  - 2 .js files in web/static/ (need TypeScript conversion)
  - 1 binary file (./bookhoard)

This addresses the trust issue: AI now has a tool to prove guideline compliance

+# Project Guidelines Verification
+
+## Quick Start
+
+Run the quick verification script:
+```bash
+make verify-guidelines
+# or
+./scripts/verify-quick.sh
+```
+
+## What It Checks
+
+1. **Custom CSS**: Detects `<style>` tags in template files (should use TailwindCSS)
+2. **JavaScript Files**: Finds .js files outside node_modules/ (should be TypeScript)
+3. **Secrets**: Checks for .env, credentials.json in repository
+4. **Build**: Verifies code compiles with `go build`
+5. **Binaries**: Finds compiled binaries in repository (should build through containers)
+
+## Understanding Results
+
+- ✅ **PASS**: Guideline followed correctly
+- ⚠️ **WARNING**: Minor issue, consider fixing
+- ❌ **ERROR**: Critical violation, should fix before committing
+
+## Exit Codes
+
+- `0`: All checks passed (or only warnings)
+- `1`: Errors found, fix before committing
+
+## Pre-commit Hook Integration (Optional)
+
+Add to `.git/hooks/pre-commit`:
+```bash
+#!/bin/bash
+./scripts/verify-quick.sh
+```
+
+This will automatically check guidelines before every commit.
+
+## CI/CD Integration
+
+Add to your GitHub Actions or GitLab CI:
+```yaml
+- name: Verify Project Guidelines
+  run: make verify-guidelines
+```
+
+## Current Known Issues
+
+The script will currently report:
+- 12 templates with custom CSS (these need Tailwind conversion)
+- 2 JavaScript files (web/static/header.js, web/static/search.js)
+- 1 binary file (./bookhoard)
+
+These should be addressed to fully comply with PROJECT_GUIDELINES.md.
