reorganize: consolidate all documentation into readmes/

- Moved 20 root-level markdown files to readmes/
- Includes COMMANDS.md, CONFIG_README.md, all UNO docs, all completion reports
- Added new: MEMORY_EDITOR_FEATURE.md, MEMORY_EDITOR_ESCAPING_FIX.md,
  CONFIG_SOURCES_ANALYSIS.md, MCP_TOOL_CALLING_ANALYSIS.md, and others
- Root directory is now clean of documentation clutter

+# ROCm Docker Image Update - February 2026
+
+## Issue Summary
+The custom-built ROCm container for llama-swap failed to build due to changes in the llama-swap repository structure:
+- UI directory changed from `ui` to `ui-svelte`
+- Build output changed from `ui/dist` to `proxy/ui_dist`
+- Go build was failing with "pattern ui_dist: no matching files found"
+
+## Resolution
+Switched to using **official llama.cpp ROCm Docker images** which are now available since PR #18439 was merged on December 29, 2025.
+
+### What Changed
+
+1. **Base Image**: Now using `ghcr.io/ggml-org/llama.cpp:server-rocm` instead of building llama.cpp from source
+2. **UI Build Path**: Updated to use `ui-svelte` directory (was `ui`)
+3. **Simpler Build**: Removed custom llama.cpp compilation stage - official image already includes optimized ROCm build
+
+### Benefits of Official Image
+
+- **Maintained by upstream**: Always up-to-date with latest llama.cpp ROCm optimizations
+- **Pre-compiled**: Faster build times, no need to compile llama.cpp from source
+- **Tested**: Official builds are tested by llama.cpp CI/CD
+- **Smaller Dockerfile**: Reduced from 4 stages to 3 stages
+
+## Updated Dockerfile Structure
+
+### Stage 1: UI Builder (Node.js)
+- Clones llama-swap repository
+- Builds UI from `ui-svelte` directory
+- Outputs to `proxy/ui_dist`
+
+### Stage 2: Binary Builder (Go)
+- Copies llama-swap source with built UI
+- Compiles Go binary with `GOTOOLCHAIN=auto`
+
+### Stage 3: Runtime (Official ROCm Image)
+- Based on `ghcr.io/ggml-org/llama.cpp:server-rocm`
+- Includes llama-server with ROCm support
+- Adds llama-swap binary
+- Creates non-root user with GPU access groups
+- Sets environment variables for AMD RX 6800 (gfx1030)
+
+## Environment Variables
+
+```bash
+HSA_OVERRIDE_GFX_VERSION=10.3.0  # RX 6800 compatibility
+ROCM_PATH=/opt/rocm
+HIP_VISIBLE_DEVICES=0
+```
+
+## GPU Access Groups
+
+- GID 187: `hostrender` group (render access)
+- GID 989: `hostvideo` group (kfd/video access)
+
+## References
+
+- **Upstream Issue**: https://github.com/ggml-org/llama.cpp/issues/11913
+- **Fix PR**: https://github.com/ggml-org/llama.cpp/pull/18439
+- **llama-swap Repo**: https://github.com/mostlygeek/llama-swap
+- **Official ROCm Images**: `ghcr.io/ggml-org/llama.cpp:server-rocm`
+
+## Testing
+
+After building, verify GPU detection:
+```bash
+docker compose up llama-swap-amd -d
+docker compose exec llama-swap-amd rocminfo
+```
+
+Expected output should show AMD RX 6800 (gfx1030) device.
+
+## Migration Notes
+
+If you had the old custom-built container running:
+1. Stop the old container: `docker compose down llama-swap-amd`
+2. Remove old image: `docker rmi miku-discord-llama-swap-amd`
+3. Rebuild with new Dockerfile: `docker compose build llama-swap-amd`
+4. Start new container: `docker compose up llama-swap-amd -d`
+
+Configuration files (`llama-swap-rocm-config.yaml`) remain unchanged.
