bootstrap.ps1

<#
.SYNOPSIS
    One-time dev setup for Vacation Recap (native Windows).

.DESCRIPTION
    Verifies the two required global tools (uv + fnm) are installed, then:
      - installs Python 3.13 + Python deps into .venv via `uv sync`
      - installs Node (per .node-version) via fnm and frontend npm deps
      - downloads the vendor ffprobe.exe and ExifTool into vendor\

    uv and fnm are single self-contained binaries; everything they install
    lives in their own per-user dirs (purgeable) plus this repo's .venv,
    frontend\node_modules, and vendor\ (all gitignored). WebView2 ships with
    Windows 11, so there is nothing else to install.

    Run once after cloning. For the day-to-day dev loop use dev.ps1.
