Switch OpenAI-compatible streaming from chat.completions.stream()
to chat.completions.create({ stream: true }) and track finish_reason
from streamed chunks directly.
This avoids the SDK's final chat-completion reconstruction path,
which could throw in preview builds while processing agent streams.
Also keep function/class names and sourcemaps in production builds
to make preview stack traces easier to read.
This issue can randomly happen when using `google/gemma-4-31b-it` model via OpenRouter.

```
Introduces a shared `toolTargeting.ts` module that resolves the active MIDI
region/track from the user's current selection, enabling tools to operate on
the correct target without requiring explicit track IDs in most cases.
Adds two new read-only tools — `list_all_tracks` and
`get_user_selected_music_range_and_track` — so the agent can inspect
available tracks and the current selection context before acting.
Also refactors `AddNotesTool` to auto-create MIDI regions when no region
exists, refactors `RemoveNotesTool`, `ReadMusicTool`, and
`ReadChordProgressionTool` to use the new targeting helpers, adds a
`buildToolHistoryContent` hook to `BaseTool` for cleaner chat history
display, and updates system prompts and tests throughout.
