feat: add GitHub issue templates for bug reports and feature requests

Adds structured YAML-based issue templates to improve issue quality.
Bug reports require version, install method, OS, repro steps, and
expected/actual behavior. Feature requests require use case and
proposed solution. Blank issues are still allowed for edge cases.
