chore: add issue templates

[satyakwok]

Brings this repo in line with the rest of the SentrisCloud fleet — every public repo ships bug.yml + feature.yml + config.yml minimum.

Templates lifted from sdk-rs's pattern (both are client-library repos). config.yml points security disclosures to security@sentriscloud.com and general questions to the Sentrix Discord.

📝 Walkthrough

Walkthrough

This PR introduces GitHub issue template infrastructure by adding three configuration files to .github/ISSUE_TEMPLATE/. The config.yml file disables blank issues and registers two contact links for security vulnerabilities and Discord support. The bug.yml template defines a structured form for bug reports with a required "What's broken?" field and optional sections for reproduction steps, expected behavior, actual behavior, and version information. The feature.yml template provides a structured form for feature requests with a required problem statement and optional proposal and alternatives fields.
