[FEATURE] Enable GitHub Discussions for community discourse

Problem

Currently, all community feedback flows through GitHub Issues, mixing bug reports, clear feature requests, and more debatable/exploratory feature discussions in one place. This makes it harder to:

• Triage actionable issues vs. open-ended discussions
• Gauge community interest on ideas before they become formal requests
• Have back-and-forth conversations without cluttering the issue tracker

Proposed solution

Enable GitHub Discussions for this repository. This would allow:

• Issues for bugs and well-defined feature requests
• Discussions for exploratory ideas, questions, showcases, and community conversations

For reference, biomejs/biome uses this approach effectively, with categories like:

• Ideas (for feature brainstorming)
• Q&A (for help and questions)
• Show and Tell (for community projects)

Alternatives considered

• Continuing with issues only, but this conflates different types of community interaction
• External forums/Discord, but GitHub Discussions keeps everything in one place and integrates with the existing workflow
