Release v0.12.2 (#26)

* feat: upgrade ComfyUI to v0.12.2 (Comfy-Org) + vendor comfy-kitchen/aimdo

* fix: restore LTXVideo compat (precompute_freqs_cis)

* fix(model_downloader): improve progress button contrast on new frontend

* chore: refresh workflow template input files

* fix(model_downloader): force high-contrast disabled progress styles

* fix: include X11/XCB libs for custom nodes (libxcb.so.1)

* fix: make manager venv deps non-overriding (avoid torch/numpy conflicts)

* feat: include ollama, pytorch-lightning, google-genai in runtime

* feat: include google-generativeai for legacy gemini nodes

* fix: patch comfyui-custom-scripts web install for read-only Nix store

* chore: bump KJNodes and GGUF to HEAD

* chore: bump Florence2, MMAudio, WanVideoWrapper to HEAD

* chore: bump LTXVideo node pack to HEAD

* feat: vendor gradio + enable sageattention via triton

* fix: patch mergekit pydantic v2 schema crash (torch.Tensor)

* chore: update flake description + changelog for ComfyUI v0.12.2

* fix(model-downloader): add HF auth header support for gated models

* docs: consolidate CLAUDE.md as single source of truth for agent instructions

Replace AGENTS.md and .github/copilot-instructions.md with symlinks to
CLAUDE.md. Merge unique content from both files (ruff/pyright config
details, shell style, commit conventions, single-file lint commands) and
fix outdated version (v0.7.0 -> v0.12.2), add launcher internals, env
vars, cross-platform Docker builds, and fix markdown lint warnings.

* fix(model-downloader): harden HF auth and unify disabled-button styles

- Parse stored_tokens as JSON instead of plain text to correctly extract
  tokens from {"huggingface.co": {"token": "hf_xxx", ...}} format
- Cover *.hf.co subdomains (e.g. cdn-lfs.hf.co) in auth header checks
  by consolidating host matching into a tuple with endswith()
- Only attach Authorization headers over HTTPS to prevent token leakage
- Extract shared disabled-button style constants (DISABLED_BG, etc.) so
  button init, CSS injection, and updateButtonStatus all use identical
  values (previously 0.35/0.18/0.5 vs 0.45/0.22/0.55)

* docs: sync CHANGELOG and README for v0.12.2 release

- Add model-downloader fixes and CLAUDE.md consolidation to CHANGELOG
- Update README data structure: .pip-packages -> .venv (PEP 405 venv),
  add fonts/ and .cache/ directories
- Update README Manager section to reflect venv-based package isolation
  and COMFY_VENV_PRECEDENCE env var

+## [Unreleased]
+
+### Changed
+- Upgraded ComfyUI to v0.12.2 (tracking `Comfy-Org/ComfyUI`)
+- Vendored new upstream deps: `comfy-kitchen`, `comfy-aimdo`
+- Added `gradio` (vendored wheel) to satisfy custom nodes that import it (e.g. ComfyUI-LLaMA-Mesh)
+- Added `sageattention` + runtime `triton` so SageAttention is available for nodes that use it
+- Consolidated `AGENTS.md` and `.github/copilot-instructions.md` as symlinks to `CLAUDE.md`
+
+### Fixed
+- Manager venv no longer overrides Nix-pinned core packages by default (prevents torch/numpy ABI conflicts)
+- Included missing X11/XCB libs in the runtime closure (fixes `libxcb.so.1` import errors)
+- Patched `mergekit` (from existing `~/AI/.venv`) at launcher-time to avoid pydantic v2 `torch.Tensor` schema crash
+- Patched `comfyui-custom-scripts` to avoid writes into the read-only Nix store
+- Model downloader: HF auth headers now cover `*.hf.co` subdomains (e.g. `cdn-lfs.hf.co`)
+- Model downloader: parse `stored_tokens` as JSON instead of plain text for correct HF token extraction
+- Model downloader: only send `Authorization` headers over HTTPS to prevent token leakage
+- Model downloader: unified disabled-button style constants across init, CSS injection, and status updates
