feat: dashboard plugin system — extend the web UI with custom tabs Add a plugin system that lets plugins add new tabs to the dashboard. Plugins live in ~/.hermes/plugins/<name>/dashboard/ alongside any existing CLI/gateway plugin code. Plugin structure: plugins/<name>/dashboard/ manifest.json # name, label, icon, tab config, entry point dist/index.js # pre-built JS bundle (IIFE, uses SDK globals) plugin_api.py # optional FastAPI router mounted at /api/plugins/<name>/ Backend (hermes_cli/web_server.py): - Plugin discovery: scans plugins/*/dashboard/manifest.json from user, bundled, and project plugin directories - GET /api/dashboard/plugins — returns discovered plugin manifests - GET /api/dashboard/plugins/rescan — force re-discovery - GET /dashboard-plugins/<name>/<path> — serves plugin static assets with path traversal protection - Optional API route mounting: imports plugin_api.py and mounts its router under /api/plugins/<name>/ - Plugin API routes bypass session token auth (localhost-only) Frontend (web/src/plugins/): - Plugin SDK exposed on window.__HERMES_PLUGIN_SDK__ — provides React, hooks, UI components (Card, Badge, Button, etc.), API client, fetchJSON, theme/i18n hooks, and utilities - Plugin registry on window.__HERMES_PLUGINS__.register(name, Component) - usePlugins() hook: fetches manifests, loads JS/CSS, resolves components - App.tsx dynamically adds nav items and routes for discovered plugins - Icon resolution via static map of 20 common Lucide icons (no tree- shaking penalty — bundle only +5KB over baseline) Example plugin (plugins/example-dashboard/): - Demonstrates SDK usage: Card components, backend API call, SDK reference - Backend route: GET /api/plugins/example/hello Tested: plugin discovery, static serving, API routes, path traversal blocking, unknown plugin 404, bundle size (400KB vs 394KB baseline). 2026-04-16 03:10:28 -07:00			`{`
