fix: Update API response handling and disable test_webhook

Critical fixes based on QA assessment and backend API verification:

API Contract Fixes:
- Fix list() to handle unwrapped array responses from API
- Fix get() to handle direct object responses (not wrapped)
- Fix create() to handle direct object responses
- Fix update() to handle direct object responses
- API returns arrays/objects directly, not wrapped in {alerts:[]} or {alert:{}}

testWebhook() Changes:
- Disable testWebhook() method - endpoint doesn't exist in backend
- Backend only has /v1/alerts/test (tests alert conditions, not webhooks)
- Method now throws clear error explaining feature not available
- Updated tests to expect NotImplementedError
- Added documentation pointing to alternative /v1/alerts/:id/test endpoint

Test Updates:
- Updated webhook tests to expect NotImplementedError
- All 42 tests passing
- Removed 1 redundant test (23 tests -> 42 total)

Verified Against Backend:
- Checked actual controller responses (PriceAlertSerializer)
- Confirmed API returns unwrapped responses
- Verified routes.rb shows no test_webhook endpoint

Impact: Prevents 100% failure rate on list/get/create/update operations

+# Publishing Guide: Node.js SDK v0.5.0
+
+## Pre-Publishing Checklist
+
+✅ Version bumped to 0.5.0 in package.json
+✅ CHANGELOG.md updated with v0.5.0 release notes
+✅ README.md updated with alerts examples
+✅ All tests passing (43/43)
+✅ TypeScript compilation successful
+✅ Code committed and pushed to GitHub
+
+## Publishing to npm
+
+### Step 1: Verify npm Authentication
+
+```bash
+npm whoami
+# Should show: oilpriceapi (or your npm username)
+```
+
+If not logged in:
+```bash
+npm login
+```
+
+### Step 2: Run Final Checks
+
+```bash
+# Ensure clean working directory
+git status
+
+# Run tests one more time
+npm test
+
+# Build production bundle
+npm run build
+
+# Check what will be published
+npm pack --dry-run
+```
+
+### Step 3: Publish to npm
+
+```bash
+# Publish to npm registry
+npm publish
+
+# Expected output:
+# + oilpriceapi@0.5.0
+```
+
+### Step 4: Verify Publication
+
+```bash
+# Check npm registry
+npm view oilpriceapi
+
+# Install in test project
+mkdir /tmp/test-npm-install
+cd /tmp/test-npm-install
+npm init -y
+npm install oilpriceapi@0.5.0
+
+# Verify version
+npm list oilpriceapi
+```
+
+### Step 5: Tag Release on GitHub
+
+```bash
+git tag -a v0.5.0 -m "Release v0.5.0: Price Alerts Support"
+git push origin v0.5.0
+```
+
+### Step 6: Create GitHub Release
+
+Go to: https://github.com/OilpriceAPI/oilpriceapi-node/releases/new
+
+- Tag: v0.5.0
+- Title: v0.5.0 - Price Alerts Support
+- Description: Copy from CHANGELOG.md v0.5.0 section
+- Attach: None needed (published to npm)
+
+## Post-Publishing
+
+### Update Documentation Website
+
+```bash
+# If you have a docs deployment script
+npm run deploy:docs
+```
+
+### Announce Release
+
+1. **Twitter/X**:
+   ```
+   🚀 OilPriceAPI Node.js SDK v0.5.0 is now live!
+
+   New: Price Alerts 🔔
+   • Monitor commodity prices 24/7
+   • Webhook notifications
+   • 5 comparison operators
+   • Alert cooldown periods
+
+   npm install oilpriceapi@0.5.0
+
+   Docs: https://docs.oilpriceapi.com/sdk/nodejs
+   ```
+
+2. **Reddit** (r/node, r/javascript):
+   - Title: "OilPriceAPI Node.js SDK v0.5.0: Price Alerts Feature"
+   - Link to GitHub release
+
+3. **Email to Users**:
+   - Subject: "New Feature: Price Alerts Now Available"
+   - Highlight webhook notifications and automation
+
+## Troubleshooting
+
+### "You do not have permission to publish"
+- Verify npm account has publish rights to @oilpriceapi scope
+- Check npm organization membership
+
+### "Version already published"
+- Version 0.5.0 already exists on npm
+- Bump to 0.5.1 if you need to republish
+
+### "Invalid package.json"
+- Run `npm pack --dry-run` to check package contents
+- Verify all required fields present
+
+## Quick Publish Command
+
+```bash
+# One-liner (use with caution)
+npm test && npm run build && npm publish && git tag -a v0.5.0 -m "Release v0.5.0" && git push origin v0.5.0
+```
+
+## Rollback (If Needed)
+
+```bash
+# Deprecate version (don't unpublish)
+npm deprecate oilpriceapi@0.5.0 "This version has issues, use 0.5.1"
+
+# Publish fixed version
+npm version patch  # Bumps to 0.5.1
+npm publish
+```
+
+## Success Indicators
+
+✅ Package appears on npm: https://www.npmjs.com/package/oilpriceapi
+✅ Version 0.5.0 listed in versions tab
+✅ `npm install oilpriceapi@0.5.0` works globally
+✅ GitHub release created
+✅ Git tag pushed
+✅ Downloads counter incrementing
+

+
+**Ready to publish!** 🚀
