opentui(phase3): launcher integration — HERMES_TUI_ENGINE dual-engine

Browse Source 
hermes --tui launches the native OpenTUI engine (Bun) when
HERMES_TUI_ENGINE=opentui (env) or display.tui_engine=opentui (config);
Ink stays the default and the shipping path is untouched.

- _resolve_tui_engine() (env > config > ink); refuses opentui on
  Windows/Termux (no Bun) -> falls back to ink with a notice.
- _make_opentui_argv() -> [bun, src/entry.real.tsx] (no build step).
- _bun_bin() with HERMES_BUN override.
- Branch at top of _make_tui_argv BEFORE _ensure_tui_node (Bun-only host
  must not bootstrap Node).
- Gate _launch_tui NODE_OPTIONS/--max-old-space-size on engine==ink (Bun
  is JSC; the V8 flag errors/ignores).

Verified end-to-end via tmux: real hermes --tui -> Bun -> OpenTUI ->
real Python gateway streamed a real reply. No-flag default still ink.

### Desktop installer (alternative)
A thin GUI installer is also available — useful if you'd rather double-click an `.exe` than open PowerShell. Download Hermes Desktop, run the installer, and on first launch the GUI calls `install.ps1` under the hood to provision Python (via `uv`), Node, PortableGit, and the rest of the dependency bootstrap described below. After the first run, the desktop app and the PowerShell-installed `hermes` CLI share the same `%LOCALAPPDATA%\hermes\hermes-agent` install and `%LOCALAPPDATA%\hermes` data directory — switch between the GUI and the CLI freely.

6. **Tiered `uv pip install`** — tries `.[all]` first, falls back to progressively smaller sets (`[messaging,dashboard,ext]` → `[messaging]` → `.`) if a `git+https` dep flakes on rate-limited GitHub. Prevents "single flake drops you to a bare install" failure mode.
7. **Auto-installs messaging SDKs** keyed off `.env` — if `TELEGRAM_BOT_TOKEN` / `DISCORD_BOT_TOKEN` / `SLACK_BOT_TOKEN` / `SLACK_APP_TOKEN` / `WHATSAPP_ENABLED` are present, runs `python -m ensurepip --upgrade` and targeted `pip install` calls so each platform's SDK is actually importable.
8. **Sets `HERMES_GIT_BASH_PATH`** to the resolved `bash.exe` so Hermes finds it deterministically in fresh shells.
9. **Adds `%LOCALAPPDATA%\hermes\hermes-agent\venv\Scripts` to User PATH and sets `HERMES_HOME=%LOCALAPPDATA%\hermes`** — exposes the `hermes` command (and points it at your data dir) after you open a new terminal.
9. **Adds `%LOCALAPPDATA%\hermes\bin` to User PATH** — exposes the `hermes` command after you open a new terminal.

On native Windows the installer sets `HERMES_HOME=%LOCALAPPDATA%\hermes`, so your data and the disposable install live under the **same** `%LOCALAPPDATA%\hermes` root: the install/runtime is the `hermes-agent\`, `git\`, `node\`, and `bin\` subdirectories, while your data files sit directly in `%LOCALAPPDATA%\hermes`. Reinstalling only replaces the `hermes-agent\` checkout, so your data survives — but because the two share a root, **don't** `Remove-Item -Recurse %LOCALAPPDATA%\hermes` if you want to keep your data; delete the `hermes-agent\` subdirectory instead. Your data directory is identical in shape to a Linux `~/.hermes`, so you can mirror it between machines.
The split is deliberate: `%LOCALAPPDATA%\hermes` is disposable infrastructure (you can blow it away and the one-liner restores it). `%USERPROFILE%\.hermes` is your data — config, memory, skills, session history — and is identical in shape to a Linux install. Mirror it between machines and your Hermes moves with you.
**Override `HERMES_HOME`:** set the environment variable to point at a different data dir (e.g. `%USERPROFILE%\.hermes` to match a Linux/WSL layout). Works the same as on Linux.

To nuke everything:
```powershell
hermes uninstall
Remove-Item -Recurse -Force "$env:LOCALAPPDATA\hermes"
# Also remove a legacy CLI/WSL data dir if you ever used one:
Remove-Item -Recurse -Force "$env:USERPROFILE\.hermes"
Remove-Item -Recurse -Force "$env:LOCALAPPDATA\hermes"
```
The `hermes uninstall` CLI subcommand also handles the case where the schtasks entry was registered under a different task name (older installs) — it searches by install path rather than by hardcoded task name.
