* fix(sdk): decode command output as GBK when it is not valid UTF-8 (#1735)

* fix: honor shared credentials on shared hosts (#1730)

* fix: size DataView list columns by the table's own width (#1713)

* fix: size DataView list columns by the table's own width

The list grid was built from every column, so columns hidden below md/lg
left empty tracks and the visible cells landed under the wrong headers.
Each width now gets a template of only its visible columns (CSS variables
+ container queries on the table, so a narrow panel counts, not the window),
the header uses the same gap as the rows, and rows use a minimum height so
wrapped cells no longer overlap.

* test: wait for the title bar offset effect before asserting

The bar shows once getTitleBarVisible resolves, but --termix-titlebar-height
is set in a later passive effect, so reading it right after findByText raced
(3-5 of 40 runs under load, on main too).

# Changelog
## 1.0.22
Plugin API 1.13.0.
### Added
- `contributes.mobile` in the manifest says how a plugin shows in the Termix mobile app: `webview`, `native` or `none`, with an optional mobile bundle, screen sizes, views and a note
- `termix-plugin build` bundles `src/mobile` into the `contributes.mobile.entry` file, and `validate` checks that it exists
- `@termix-ssh/plugin-sdk/frame-host` runs one plugin view outside the shell, with core's bridge, registries and CSS, so the mobile app can show `webview` plugins
- SSH transport providers get the host's owner, sync id, connection origin and local only flag in `claims` and `open`, and core's SSH relay takes a `syncId` instead of a host id
- `ctx.sync.host.entities.idsOf` maps sync ids to the local ids of the user's own rows of one type
- Rail items take `useStatus` for a small ok, warning or error dot on the icon
- `shell.editHost(hostId)` opens the editor of a saved host
- A sync entity can be read only with `load`, `write` and `erase`, so a plugin can sync rows a user does not own, like a shared library, down to linked desktops
- `getFolderAuthOverride` and `setFolderAuthOverride` in `@termix-ssh/plugin-sdk/ui` read and set a user's own login for the shared hosts in a folder
### Fixed
- `@termix-ssh/plugin-sdk/ui` is built in production mode, so outside Termix it no longer sends requests to the Vite dev server path
- `execCommand` buffers output and decodes it once as strict UTF-8 with a GBK fallback, exposed as `decodeCommandOutput`, so messages from a Windows host on a legacy codepage are readable instead of � characters
## 1.0.21
Plugin API 1.12.0.
### Added
- `@termix-ssh/plugin-sdk/host-scripts`: Docker, Linux metrics, systemd, journal and OpenRC command builders and parsers, plus `scriptShell()` and `passwordSudoScript()` to send scripts to `bash -s` on stdin. It has no Node or ssh2 imports, so the Termix mobile app runs the same code

### Mobile app
`contributes.mobile` says how the plugin shows in the Termix mobile app. Leave it out and the app treats the
plugin as having nothing to show (official plugins are mapped by the app itself).
```json
"mobile": { "mode": "webview", "views": ["hello"], "sizes": ["phone", "tablet"] }
```
| Field | Notes |
| --------- | ------------------------------------------------------------------------------------------------------------------------------------------------- |
| `mode` | `webview` (the app shows your UI from the server), `native` (the app has its own screens) or `none`. |
| `entry` | `webview` only. A bundle made for the app, like `dist/mobile.js`, next to `frontend.js`. Unset: your normal frontend runs in a phone sized frame. |
| `sizes` | `webview` only. `phone`, `tablet` or both (the default). |
| `views` | `webview` only. Ids from your `tabs`, `panels` or `dashboardCards` the app offers. Default: every tab. |
| `feature` | `native` only. The app feature that stands in for the plugin. Default: the plugin id. |
| `note` | A locale key or plain text the app shows next to the plugin. |
`build` makes `entry` from `src/mobile/index.tsx`, and it shares `frontend.css`.
How a `webview` plugin runs in the app:
- Only your plugin loads, with the same app object, SDK hooks and `/ui` kit as the web app. Each view opens
on its own screen: a tab with `host-context-menu` in `openFrom` opens from a host, the rest from the app's
plugin list.
- Every request and socket goes through the app, which adds the login, proxy headers and client
certificate. The app only lets through your own `/plugin-api`, `/plugin-ws` and `/plugin-assets`, your
settings and a short list of core reads (hosts, folders, permissions, current user, version, health,
activity). Other core routes answer 403, so call your own backend instead.
- Images load straight from the server, without proxy headers or a client certificate.
- Nothing in `localStorage` survives closing the view. Keep preferences in settings.
- Other plugins' views, extensions and components are not there, and neither is the shell (`useShell()`
is null). `/ui` names newer than the app's copy of the SDK make the view say it needs a newer app.
- The app checks your `engine.api` against the plugin API of its own copy of the SDK. When the app's API
is too old for the range, it asks the user to update the app instead of opening the view. When the range
is for an older API major, it asks to update the plugin. Ask only for the API you use.
- Turning a plugin off on the server hides it in the app the next time the app checks: when it comes back
to the front, when the list is pulled down, or when any request answers 503 with your `pluginId`.
Termix 26.10.5 and older refuse any manifest with `mobile`, so a plugin that declares it needs
`"engine": { "termix": ">=26.10.6", "api": "^1.13" }`.
Capabilities and permissions are different things. A capability (`hosts:read`, with a colon) is what your
code may reach. A permission (`hello.use`, with a dot) is what a user may do.
