feat(tools): issue_get, release_create, repo_delete (#11, #17, #20)

issue_get: GET /repos/{owner}/{repo}/issues/{number} — full issue with labels, assignees, comment count
release_create: POST /repos/{owner}/{repo}/releases — create release and tag in one call
repo_delete: DELETE /repos/{owner}/{repo} — confirm=<repo name> required, blocks accidents
