### What happened

`default/hypr/apps/pip.lua` tries to float and pin the Google Meet Picture-in-Picture (PiP) window with:

```lua
o.window({ tag = "chromium-based-browser", title = "^Meet - .+" }, { ... float = true, pin = true ... })
```

The regex uses an ASCII hyphen, but Chromium titles the Meet Picture-in-Picture window with an **en dash** (U+2013):

```
$ hyprctl clients -j | jq -r '.[] | select(.class=="chromium") | .title'
Meet – Team standup
```

```
b'Meet \xe2\x80\x93 Team standup'
```

So the rule never matches. The window keeps the `tile = true` from
`default/hypr/apps/browser.lua`:

```lua
o.window({ tag = "chromium-based-browser" }, { tag = "-default-opacity", tile = true, opacity = "1.0 0.985" })
```

Tiled, it is then auto-added to the focused window group (`group:auto_group` defaults to `true`)
and inherits the group's geometry, so the small PiP overlay opens at full group size:

```
title: 'Meet – Team standup'  initialTitle: 'Meet – Team standup'
floating: False   grouped: 3 windows   size: [2536, 1362]   tags: ['chromium-based-browser*']
```

### What was expected

The PiP overlay floats, pins, and sizes to 600x338 in the corner, as `pip.lua` intends,
and never joins a window group.

### Steps to reproduce

1. Group a couple of windows on a workspace with `SUPER + G`.
2. Join a Google Meet call in Chromium on that workspace.
3. Switch to another tab so Meet spawns its PiP overlay window.
4. The overlay opens tiled inside the group at full group size instead of floating pinned.

### Suggested fix

Accept the en dash (and em dash) in the title match:

```lua
o.window({ tag = "chromium-based-browser", title = "^Meet (-|–|—) .+" }, { ... })
```

Verified locally as a user override in `~/.config/hypr/hyprland.lua`: the overlay floats,
pins, and sizes correctly, and no longer joins the group. Adding `group = "deny"` to the
same rule also blocks accidental manual grouping.

Side note: the rule exists on `quattro` but was dropped from `dev`'s `pip.lua` entirely,
so on `dev` the Meet overlay has no rule at all and hits the same behavior.
