halo's llama-server now runs in router mode where the model field selects
a preset (coder/fast/bge-m3); the old "halo-8000" name is no longer valid.
Use the fast MoE model for the Talk bot's responses.
Resolves the URL through the Odesli public API (api.song.link) and
replies with the canonical song.link page plus per-platform deep links
(Spotify, Apple Music, YouTube/YT Music, Tidal, Deezer, Amazon Music,
SoundCloud). Country is pinned to DE.
The bot no longer shells out to `opencode run`. Instead it POSTs to the
OpenAI-compatible /chat/completions endpoint exposed by llama-server on
halo.hoyer.tail:8000 directly. This removes the Bun/sqlite cold-start
overhead per request, drops the pkgs.opencode runtime dependency, and
eliminates the ExecStartPre dance that materialized config.json into the
service's $HOME.
Conversation history is now stored as a proper OpenAI `messages` list
with system/user/assistant roles, instead of the XML blob that was
inlined into a single `opencode run` argument. The interactive opencode
setup (config/opencode/config.json) is unchanged — only the bot stops
depending on it.
The module gains a `modelBaseUrl` option; `model` is now the bare model
name (`halo-8000`) without the provider/ prefix that the opencode CLI
required.
Mirrors the existing nextcloud-claude-bot setup but invokes `opencode run`
against the local `halo-8000` provider/model. The bot listens on
127.0.0.1:8086, is exposed via the `/_opencode-bot/` location on
nc.hoyer.xyz, and uses `@Halo` as its mention trigger in group chats.
The opencode config (config/opencode/config.json) is installed into the
service's $HOME/.config/opencode/ on each start, so the bot picks up the
same provider definition the user uses interactively. The model map keys
are renamed to `halo-8000` / `halo-8001` so the canonical
`provider/model` reference works without an alias indirection.
