feat(repo): add +activity for the project trends feed

Wraps GET /:owner/:repo/activity (ProjectTrendsController#index) with
the server's documented filters:

- --type: Issue | PullRequest | Version
- --status: create | close | journal
- --time: only events from the past N days (integer-validated)

Production-verified on gitlink.org.cn (filtered Issue/close feed
returns trends plus aggregate counts). Unit test covers query shape
and the --time guard; README example and bilingual i18n keys.
