Versionless installer asset names, stable latest-download README links

- DEVMODE removed; FASTAPI_VUE=MEDIAHIVE is set at entrypoints and
  fastapi_vue.env drives dev-mode checks
- CLI roots now reach the server via fastapi-vue's env(Config) teleport
  (mediahive.config.config) instead of MEDIAHIVE_ROOTS
- Legacy media_folder config field and migration removed
- mediahive.* logger level set via log_config (DEBUG in dev, INFO in prod)
  in both server.run() and winmain's patched uvicorn config

 Note that `.mediahive` folder is created in your media folder to hold all the metadata and preview clips, avoiding the lengthy processing that you will see on initial startup.

 - `GET /api/assets/{root_id}/{asset_type}/{asset_path:path}` is constrained to `<root>/.mediahive/{asset_type}` where `asset_type` is one of `movies`, `series`, `people`.
 - `GET /api/meta/{root_id}/{meta_key}` supports metadata keys currently limited to `playback-state` and `scanignore`.
 - `GET /api/player/status` returns `{ "remote": true|false }`.
-- Roots may also be provided at startup via the `MEDIAHIVE_ROOTS` environment variable (JSON dict of name → path), which overrides the persisted configuration.
+- Roots may also be provided at startup via CLI arguments (`mediahive /path/to/media ...`), which are passed to the server through fastapi-vue's env config (`mediahive.config.config`) and override the persisted configuration.
 - Assumed playback: after `POST /api/play/{root_id}` the launched item is assumed to be playing while the frontend reports no input activity. On the next `POST /api/activity` the guessed position (`resume base + elapsed`, capped at the TMDb runtime) is written once; watches under 5 minutes are discarded (a peek is not progress). A resume entry written by another tracker (e.g. the GUI's MPC-BE tracker) during the session overrides the guess. The MPC-BE tracker likewise ignores sessions shorter than 5 minutes.

 The helper scripts are directly executable via their `uv run` shebang (on Windows, run them with `uv run scripts/<name>.py`):
 
-- `./scripts/guibuild.py` builds the PyInstaller desktop app and a versioned portable ZIP under `build/`.
-- `./scripts/release.py` publishes a release to the Gitea releases page.
+- `./scripts/guibuild.py` builds the PyInstaller desktop app and packages it with Velopack under `build/`: per-user `Setup.exe` (Windows), `.pkg` installer (macOS), `.AppImage` (Linux), plus the update feed in `build/velopack/`. On Windows it also creates a `-win64-portable.zip` (no auto-updates). Requires node/npm and the .NET SDK (>= 10 runtime) installed on the build host; `vpk` and ffmpeg are downloaded once into a persistent user cache (`~/.cache/mediahive-build`, `%LOCALAPPDATA%\mediahive-build` on Windows).
+- `./scripts/release.py` publishes a release to the Gitea releases page, uploading the platform artifacts and the Velopack update feed files — installed apps auto-update from the latest release.
 
 Python packaging builds the frontend automatically through the hatch build hook `scripts/fastapi-vue/buildhook.py` (see `pyproject.toml`), so wheels and sdists always ship a fresh `mediahive/frontend-build`.
