Brand the fork as Hellion Chat with independent plugin state

Switch the assembly name to HellionChat so Dalamud uses
pluginConfigs/HellionChat for our config file and database
directory, instead of sharing those locations with the upstream
Chat 2 plugin. Code namespace stays ChatTwo.* so upstream
cherry-picks apply cleanly.

Rename the DalamudPackager manifest to HellionChat.yaml with
fork-specific name, author, repo URL, description, tags and
changelog. Plugin.PluginName becomes "Hellion Chat".

Add a one-shot migration in the plugin constructor that runs
before GetPluginConfig: if pluginConfigs/ChatTwo.json or the
ChatTwo/ directory exist and our equivalents don't, move them
into the HellionChat layout. Idempotent: only fires on the first
load where legacy paths are present and ours are not.

+  Hellion Chat is a privacy-focused, Linux-aware fork of Chat 2.
+
+  Same chat replacement you know from upstream, with extra controls
+  for what actually gets stored:
+
+  - Channel whitelist for database persistence (GDPR Art. 25)
+  - Privacy-First defaults: only your own conversations are kept
+  - Failsafe for unknown ChatTypes (default OFF)
+  - Independent plugin state (own config + database directory)
+
+  Based on Chat 2 by Infi and Anna, licensed under EUPL-1.2.
