feat(bootstrap): zero-config auto-generated secrets on first run

Resolves root cause of #252 (Electron black screen) and #249 (OAuth fail)
for users running with zero configuration (no .env needed).

New: scripts/bootstrap-env.mjs
- Auto-generates JWT_SECRET (64 bytes), STORAGE_ENCRYPTION_KEY (32 bytes),
  API_KEY_SECRET (32 bytes) if missing or empty
- Persists to {DATA_DIR}/server.env — survives restarts, Docker volume
  remounts, and upgrades without changing secrets
- Reads .env from CWD (user overrides), then merges process.env (highest prio)
- Logs friendly warnings for missing optional OAuth secrets

Updated: run-standalone.mjs + run-next.mjs
- Call bootstrapEnv() before spawning server — covers npm + Docker paths

Updated: electron/main.js (synchronous inline — CJS cannot await import ESM)
- Reads userData/server.env, generates missing secrets with crypto.randomBytes()
- Persists back to server.env, sets OMNIROUTE_BOOTSTRAPPED=true

New: BootstrapBanner.tsx + page.tsx update
- Dismissable amber banner on dashboard home when running in zero-config mode
- Shows where server.env is located and how to customize secrets

+## [2.2.5] — 2026-03-10
+
+> ### 🔧 Zero-Config Bootstrap · 🐛 Electron Black Screen Fix
+
+### Features
+
+- **Zero-config bootstrap (#252, #249)** — OmniRoute now auto-generates required secrets on first run across all deployment modes (npm, Docker, Electron Desktop App):
+  - `JWT_SECRET` (64-byte hex) — required for auth/sessions
+  - `STORAGE_ENCRYPTION_KEY` (32-byte hex) — required for SQLite encryption
+  - `API_KEY_SECRET` (32-byte hex) — required for API key signing
+  - Secrets are persisted to `{DATA_DIR}/server.env` and survive restarts, Docker volume remounts, and upgrades
+  - Friendly startup warnings if OAuth secrets (Antigravity, iFlow, Gemini) are not configured
+  - New **`scripts/bootstrap-env.mjs`** module — single source of truth for zero-config initialization
+
+### Bug Fixes
+
+- **Electron black screen on macOS/Windows/Linux** — The Next.js server was crashing silently because `JWT_SECRET` and `STORAGE_ENCRYPTION_KEY` are never present in desktop OS environments. Fixed by calling `bootstrapEnv()` before spawning `server.js`, with secrets persisted to Electron's `userData` directory.
+- **Dashboard bootstrap banner** — Added dismissable amber warning banner on the dashboard home when running in zero-config mode, showing where `server.env` is stored and how to customize secrets.
+
+### Note for Docker users
+
+Previously, `--env-file .env` was required to pass secrets to the container. Now OmniRoute will generate and persist them automatically in the mounted volume. Existing `DATA_DIR` secrets are always respected.
