fix: insertion issue

[Junyi-99]

description:

The "insert" button is always disabled because we cleared the selectedText and selectionRange.

---

Note

Fixes selection handling in chat input and tightens TS config.

• In PromptInput, submit() now conditionally clears selection: if selectedText exists, call setSelectedText(null) and setSurroundingText(null); otherwise use clear(). Added corresponding store getters and updated useCallback deps
• Minor: tsconfig.app.json removes bun from types and excludes **/*.test.ts(x) from the app build

Pull request overview

This PR fixes an issue where the "insert" button in the text patches component was always disabled after sending a message. The root cause was that the clearSelection() function was clearing the selectionRange, which is needed for the insert button to be enabled.

Changes:

• Modified the selection clearing logic in the submit handler to preserve selectionRange when only selectedText exists
• Removed "bun" from TypeScript types configuration and added test file exclusions
