chore: bump version to 1.3.2 for release

[umireon]

I'd like to release 1.3.2, it will have one critical bug fix on Mac.

The following are the changes between version 1.3.1 and HEAD of the royshil/obs-backgroundremoval repository:

---

GitHub workflows, templates, and documentation

• Replaced old Markdown-based issue templates (bug_report.md, feature_request.md) with new YAML-based forms (bug_report.yml, feature_request.yml) and added a .github/ISSUE_TEMPLATE/config.yml for custom issue/discussion/contact links.
• FAQ: Added a comprehensive FAQ.md file with 50 common Q&A covering install, configuration, troubleshooting, technical details, and community resources.
• .gitignore now explicitly includes FAQ.md.
• Documentation (under pages/):
  • Updated the user and developer guides (notably on Linux/macOS).
  • Added or extended interactive help (new interactive-help.astro page and an interactive chatbot UI).
  • Major bump in the dependencies for the website, notably adding Svelte and AI-related packages to support the new interactive help system.

Website frontend

• New Svelte integration in Astro, including a custom chatbot at pages/src/components/Chat.svelte and supporting LLM logic in pages/src/lib/llm.ts (Svelte store for local LLM-based chatbot).
• Many changes to styling and page layout to support new FAQ and interactive features.
• Added a direct entry point on the homepage for "Ask Anything (Experimental)" interactive help.

Core Plugin (C++)

• Concurrency/mutex fix in background-filter.cpp:
  • Saving of backgroundMask for the next frame is now protected by a mutex (std::lock_guard<std::mutex> lock(tf->outputLock);), making it thread-safe.
  • Rendering function improved: if backgroundMask is empty when rendering, a warning is logged, OBS skips the filter for that frame, and returns early instead of crashing or producing undefined behavior.
  • Creation of the alpha texture remains protected by a mutex, but now checks for the empty case robustness.

Summary of impact

• Improved issue reporting experience and guidance for users.
• Extensive FAQ added, making user troubleshooting and onboarding easier.
• Added experimental interactive chatbot help to the documentation site (runs locally in browser).
• Website frontend now supports Svelte and LLM-powered chat in addition to Astro/Markdown.
• Safer handling of background masks in the C++ filter code, reducing race conditions and crashes under certain error cases during OBS plugin execution.
