Bug 1: Gitee create/update issue API uses /repos/{owner}/issues (no repo
in path, unlike GitHub). Fix issue create to POST to /repos/{owner}/issues
with repo as body param. Fix issue view and close to use same pattern.
Bug 2: gitee api command did not accept --json flag. Add --json option:
- without --json: pretty-printed JSON (default)
- with --json: compact JSON (pipe-friendly)
