# Plan: Browser Update Check on Startup

## Overview
Add a startup version check that queries the release server for the latest browser version. If a newer version exists, show a dialog offering to download it (same UX as agent download). Also add browser routes to the release server (separate Gitea repo).

## Part 1: Release Server — Add Browser Routes

### New file: `hiveops-release/src/routes/browser.js`
Mirror `routes/agent.js` but for a separate browser Gitea repo:
- Env var: `GITEA_BROWSER_REPO` (default: `hiveops-browser`), reuses existing `GITEA_URL`, `GITEA_TOKEN`, `GITEA_OWNER`
- Asset mapping: `windows` → `.exe`, `linux` → `.AppImage`
- Endpoints:
  - `GET /browser/latest` — returns `{ version, name, published, platforms }`
  - `GET /browser/download?platform={windows|linux}&version={optional}` — streams binary
  - `GET /browser/versions` — lists all versions
- Own release cache (separate from agent)

### Modify: `hiveops-release/src/index.js`
- Import and mount `browserRoutes` alongside `agentRoutes`

## Part 2: Browser — API Client Methods

### Modify: `hiveops-browser/src/main/api-client.js`
Add three methods:
- `checkForBrowserUpdate()` — `GET ${releaseUrl}/browser/latest`, compare version to `app.getVersion()`, return `{ updateAvailable, latestVersion, currentVersion }`
- `downloadBrowser(platform, savePath, onProgress, abortSignal)` — same pattern as `downloadAgent` but hits `/browser/download`
- `getBrowserFilename(platform)` — HEAD to `/browser/download` for Content-Disposition filename

## Part 3: Browser — Startup Check + Download Flow

### Modify: `hiveops-browser/src/main/main.js`
In `checkServicesAndStart()`, after main window is created (~line 197):
1. Call `apiClient.checkForBrowserUpdate()` (non-blocking, won't delay startup)
2. If update available, show dialog: "New version v{latest} available. You are running v{current}. Download?"
   - Buttons: **Download** / **Later**
3. On "Download":
   - Auto-detect platform via `os.platform()` (no picker needed)
   - Get server filename via `getBrowserFilename()`
   - Show save dialog → download with progress window (reuse existing `openDownloadProgress`)
4. On "Later": dismiss silently
5. Entire check wrapped in try/catch — failures logged, never block the app

## Files Changed

| File | Action |
|------|--------|
| `hiveops-release/src/routes/browser.js` | **New** |
| `hiveops-release/src/index.js` | **Modify** — mount browser routes |
| `hiveops-browser/src/main/api-client.js` | **Modify** — 3 new methods |
| `hiveops-browser/src/main/main.js` | **Modify** — update check + download flow |

## Verification
1. `GET /browser/latest` returns version info from release server
2. Browser logs show update check on startup
3. If newer version exists, update dialog appears after main window loads
4. "Download" → save dialog with server filename → progress → completion
5. "Later" → dismissed, app continues
6. Release server unreachable → app starts normally, error logged silently
