Candango Issues

Use $to-issues as the issue-slicing engine.

Before use $to-issues, confirm with user the tracker (GitHub, Linear, Jira, or other), besides the markdown file

Then, convert each $to-issues issue to issue-template.md and store them in docs/features/<feature-slug>/issues.md.

Hard rule: do not write issues.md, create tracker issues, or mutate any tracker until the user explicitly approves the proposed issue breakdown.
