BazChat

## 001 — Initial release

A modern chat replacement for the Baz Suite. Owns its chat windows
end-to-end — Blizzard's default chat is hidden, BazChat's frames
inherit ChatFrameMixin so the standard message formatter, hyperlinks,
edit-box history, BN whisper routing, and combat log all keep working.

### Features

- **Replica chat windows** with NineSlice chrome that matches the
rest of the Baz Suite UI.
- **Multiple containers**. The main dock holds your tabs; any tab
can be popped out into its own floating window. Popped windows are
first-class — own tab strip, own "+" button to add tabs in place,
own resize handle, own Edit Mode registration. Tabs migrate between
containers via a "Move to" submenu on shift+right-click.
- **Per-tab channel filtering**. Right-click a tab → toggle which
chat categories and joined channels appear there. Defaults match
the Blizzard tab presets (Guild / Trade / Log).
- **Persistent history across `/reload` and relog**. Default 500
lines per tab, configurable 100 – 2000.
- **Two-column timestamps** with a channel-colored vertical bar per
message (green for guild, pink for whispers, custom-channel colors
honored from `ChatTypeInfo`).
- **Up/Down arrow** in the chat editbox cycles through your typed-
message history. Survives `/reload`.
- **Auto-show modes per tab** — Always / In a city / In a party /
In a raid / In combat / In a battleground / In a dungeon.
- **Drag-to-reorder tabs**. Hold a tab for two seconds and drag.
- **Lock toggle** per chat window. Unlocked: drag the dock from any
empty area in the tab row, resize from the bottom-right grabber,
no need to enter Edit Mode. Locked: chat is fixed in place.
- **Per-frame copy-chat icon** on the chrome's top-right opens
BazCore's copy dialog.
- **Modern modifier-click context menu**. Shift+right-click a tab
for Rename / Channels / Clear messages / Move to / Lock / Delete.
