fix(gui): Resolve AttributeError in imscope.indent and stabilize render loop

- Add 'indent' context manager to src/imgui_scopes.py.
- Refactor manual imgui.indent/unindent calls in src/gui_2.py to use imscope.indent.
- Fix cascading ImGui assertion failures caused by Open/Close mismatches during exceptions.
- Finalize 'Selectable Thinking Monologs' track.

     - [x] If `thinking_read_mode` is `False` (Pure mode), use `render_selectable_label(app, f"think_text_...", content, multiline=True, height=-1)` to make the text selectable and copyable.
 
 ## Phase 2: Verification
-- [ ] Task: Verification
-    - [ ] Verify that thinking traces in the Discussion Hub can be toggled between Pure and Read modes.
-    - [ ] Verify that text can be selected and copied via Ctrl+C in Pure mode.
-    - [ ] Verify that the change does not crash other areas rendering thinking traces (like Comms History).
