fix: release 3.2.3 — metadata parsing, null-safe saves, auto-hide, tag search

- fix(#75): stop SaveImage patch from writing the last-run prompt into every
  PromptManager node (negative prompts were saved as copies of the positive)
- fix(#75): replace four duplicated metadata parsers with a shared
  web/js/comfy-metadata.js that traces sampler links (KSampler, CFGGuider /
  SamplerCustomAdvanced, LoRA chains, ControlNet pass-through, any checkpoint
  loader) and recovers per-node text for images saved by older versions
- fix(#143): treat null JSON body fields as empty in prompt API handlers
- fix(#149): keep auto-hide timeout 0 (disabled) instead of falling back to
  the default; validate result_timeout on save
- feat(#150): support tag:name filters in the node search box
- docs(#142): scan dialog mentions A1111/Forge metadata support
- docs(#144): fix ComfyUI-Lora-Manager links
- ci: run JS tests with node --test
