c0f40c7a92 fix: #1623
Some checks failed
CI / test (pull_request) Failing after 49s
CI / validate (pull_request) Failing after 56s
Review Approval Gate / verify-review (pull_request) Failing after 5s
- Add portal registry watcher for hot-reload
- Add js/portal-registry-watcher.js
- Add tests (9 tests, all passing)
- Add script to index.html

Features:
1. Watch portals.json for changes
2. Hot-reload portal scene objects
3. Cache-busting with _registry_ts query
4. Custom event dispatch for other modules
5. Portal lookup by ID and status

Addresses issue #1623: feat: portal hot-reload from portals.json without server restart

Usage:
- Start watching: watcher.startWatching()
- Stop watching: watcher.stopWatching()
- Get portal: watcher.getPortalById('portal-id')
- Get by status: watcher.getPortalsByStatus('online')
