- Added slash-command coverage for /model opening the session selector.
Fixes#2846
- Removed the built-in `background` (`bg`) slash command and its `handleBackgroundCommand` path from the interactive flow.
- Deleted background event subscription and shutdown handling by removing `handleBackgroundEvent` from the event, input, and interactive controllers.
- Simplified `InteractiveModeContext` by dropping background-only fields and helpers such as `isBackgrounded`, background UI context creation, and background event callbacks.
- Added setup wizard with provider login, glyph mode, and theme scenes shown once per setup version.
- Wired `omp setup` (no args) to trigger the wizard in a TTY; `--check`/`--json` still show help.
- Extracted `gradientEscape` and exported `PI_LOGO`/`ShineConfig` from welcome for shared use in splash/outro.
- Fixed race condition in `setSymbolPreset`/`setColorBlindMode` by tracking load request IDs.
- Mirrors the alt+p keybinding for switching provider mid-session.
- Added test verifying showModelSelector is called with temporaryOnly: true.
- Updated tips.txt to document the /switch shortcut alongside alt+p.
