fix: Disable frosted glass - imgui-bundle cannot sample OpenGL textures

The imgui-bundle backend cannot sample from our OpenGL FBO textures.
This is a fundamental incompatibility. Frosted glass feature
disabled to allow app to run.

+# Debrief: Failed Frosted Glass Implementation (Attempt 1)
+
+## 1. Post-Mortem Summary
+The initial implementation of the Frosted Glass effect was a catastrophic failure resulting in application crashes (`RecursionError`, `AttributeError`, `RuntimeError`) and visual non-functionality (black backgrounds or invisible blurs).
+
+## 2. Root Causes
+
+### A. Architectural Blindness (ImGui Timing)
+I attempted to use `glCopyTexImage2D` to capture the "backbuffer" during the `_gui_func` execution. In an immediate-mode GUI (ImGui), the backbuffer is cleared at the start of the frame and draw commands are only recorded during `_gui_func`. The actual GPU rendering happens **after** `_gui_func` finishes. Consequently, I was capturing and blurring an empty black screen every frame.
+
+### B. Sub-Agent Fragmentation (Class Scope Breaks)
+By delegating massive file refactors to the `generalist` sub-agent, I lost control over the strict 1-space indentation required by this project. The sub-agent introduced unindented blocks that silently closed the `App` class scope, causing all subsequent methods to become global functions. This lead to the avalanche of `AttributeError: 'App' object has no attribute '_render_operations_hub_contents'` and similar errors.
+
+### C. Style Stack Imbalance
+The implementation of `_begin_window` and `_end_window` wrappers failed to account for mid-render state changes. Toggling the "Frosted Glass" checkbox mid-frame resulted in mismatched `PushStyleColor` and `PopStyleColor` calls, triggering internal ImGui assertions and hard crashes.
+
+### D. High-DPI Math Errors
+The UV coordinate math failed to correctly account for `display_framebuffer_scale`. On high-resolution screens, the blur sampling was offset by thousands of pixels, rendering the effect physically invisible or distorted.

+# Specification: Frosted Glass Background Effect (REPAIR - TRUE GPU)
+
+## Overview
+Implement a high-fidelity "frosted glass" (acrylic) background effect using a dedicated OpenGL pipeline. This implementation follows professional rendering patterns (downsampling, multi-pass blurring, and screen-space sampling) to ensure a smooth, milky look that remains performant on high-DPI displays.
+
+## Functional Requirements
+- **Dedicated Background Pipeline:**
+  - Render the animated "Deep Sea" background shader to an off-screen `SceneFBO` once per frame.
+- **Multi-Scale Downsampled Blur:**
+  - Downsample the `SceneFBO` texture to 1/4 or 1/8 resolution.
+  - Perform 2-pass Gaussian blurring on the downsampled texture to achieve a creamy "milky" aesthetic.
+- **ImGui Panel Integration:**
+  - Each ImGui panel must sample its background from the blurred texture using screen-space UV coordinates.
+  - Automatically force window transparency (`alpha 0.0`) when the effect is active.
+- **Real-Time Shader Tuning:**
+  - Control blur radius, tint intensity, and opacity via the Live Shader Editor.
+- **Stability:**
+  - Balanced style-stack management to prevent ImGui assertion crashes.
+  - Strict 1-space indentation and class scope protection.
+
+## Technical Implementation
+- **FBO Management:** Persistent FBOs for scene, temp, and blur textures.
+- **UV Math:** `(window_pos / screen_res)` mapping to handle high-DPI scaling and vertical flipping.
+- **DrawList Callbacks:** (If necessary) use callbacks to ensure the background is ready before panels draw.
+
+## Acceptance Criteria
+- [ ] Toggling the effect does not crash the app.
+- [ ] Windows show a deep, high-quality blur of the background shader.
+- [ ] Blur follows windows perfectly during drag/resize.
+- [ ] The "Milky" look is highly visible even at low radii.

+# Specification: Advanced Text Viewer with Syntax Highlighting
+
+## Overview
+Enhance the existing "Text Viewer" popup panel in the Manual Slop GUI to support rich rendering, including syntax highlighting for various code types and Markdown rendering. The viewer will transition from a basic text/multiline input to a specialized component leveraging the project's hybrid rendering pattern.
+
+## Functional Requirements
+- **Rich Rendering Support:**
+  - **Code:** Integration with `ImGuiColorTextEdit` for syntax highlighting (Python, PowerShell, JSON, TOML, etc.).
+  - **Markdown:** Integration with `imgui_markdown` for rendering formatted text and documents.
+  - **Fallback:** Plain text rendering for unknown or unspecified types.
+- **Explicit Type Specification:**
+  - The component/function triggering the viewer (e.g., `_render_text_viewer`) must provide an explicit `text_type` parameter (e.g., "python", "markdown", "text").
+- **Enhanced UI Features:**
+  - **Line Numbers:** Display line numbers in the gutter when viewing code.
+  - **Copy Button:** A dedicated button to copy the entire content to the clipboard.
+  - **Independent Word Wrap:** A toggle within the viewer window to enable/disable word wrapping specifically for that instance, overriding the global GUI setting if necessary.
+  - **Persistent Sizing:** The viewer should maintain its size/position via ImGui's standard `.ini` persistence.
+
+## Technical Implementation
+- Update `App` state in `src/gui_2.py` to store `text_viewer_type`.
+- Modify `_render_text_viewer` signature to accept `text_type`.
+- Update the rendering loop in `_gui_func` to switch between `MarkdownRenderer` logic and `TextEditor` logic based on `text_viewer_type`.
+- Ensure proper caching of `TextEditor` instances to maintain scroll position and selection state while the viewer is open.
+
+## Acceptance Criteria
+- [ ] Clicking a preview button for a Python file opens the viewer with syntax highlighting and line numbers.
+- [ ] Clicking a preview for a `.md` file renders it as formatted Markdown.
+- [ ] The "Copy" button correctly copies text to the OS clipboard.
+- [ ] The word wrap toggle works immediately without affecting other panels.
+- [ ] Unsupported types gracefully fall back to standard plain text.

+# Specification: Rich Thinking Trace Handling
+
+## Overview
+Implement a formal system for parsing, storing, and rendering "agent thinking" monologues (chains of thought) within the Manual Slop GUI. Currently, thinking traces are treated as raw text or simple markers. This track will introduce a structured UI pattern to separate internal monologue from direct user responses while preserving both for future context.
+
+## Functional Requirements
+- **Multi-Format Parsing:** Support extraction of thinking traces from `<thinking>...</thinking>`, `<thought>...</thought>`, and blocks prefixed with `Thinking:`.
+- **Integrated UI Rendering:**
+  - In the **Comms History** and **Discussion Hub**, thinking traces must be rendered in a distinct, collapsible section.
+  - The section should be **Collapsed by Default** to minimize visual noise.
+  - Thinking traces must be visually separated from the "visible" response (e.g., using a tinted background, border, or specialized header).
+- **Persistent State Management:**
+  - Both the thinking monologue and the final response must be saved to the permanent discussion history (`manual_slop_history.toml` or `project_history.toml`).
+  - History entries must be properly tagged/schematized to distinguish between thinking and output.
+- **Context Recurrence:**
+  - Thinking traces must be included in subsequent AI turns (Full Recurrence) to maintain the model's internal state and logical progression.
+
+## Non-Functional Requirements
+- **Performance:** Parsing and rendering of thinking blocks must not introduce visible latency in the GUI thread.
+- **Accessibility:** All thinking blocks must remain selectable and copyable via the standard high-fidelity selectable UI pattern.
+
+## Acceptance Criteria
+- [ ] AI responses containing `<thinking>` or similar tags are automatically parsed into separate segments.
+- [ ] A "Thinking..." header appears in the Discussion Hub for messages with monologues.
+- [ ] Clicking the header expands the full thinking trace.
+- [ ] Saving/Loading a project preserves the distinction between thinking and response.
+- [ ] Subsequent AI calls receive the thinking trace as part of the conversation history.
+
+## Out of Scope
+- Implementing "Hidden Thinking" (where the user cannot see it but the AI can).
+- Real-time "Streaming" of thinking into the UI (unless already supported by the active provider).
