feat(ci): enhance opencode workflow with comprehensive triggers

Expand opencode workflow to support multiple trigger events, add
timeout/concurrency controls, and simplify command syntax. This brings
the workflow to parity with the claude.yml pattern.

Changes:
- Add pull_request_review_comment, issues, and pull_request_review
  triggers
- Add 30-minute timeout to accommodate extended Codex runs
- Add concurrency grouping to prevent duplicate runs
- Expand authorization checks to handle all event types with null
  checks
- Simplify command from /oc-gpt-5-codex to /oc-codex
- Add version pinning documentation comment
