* fix(#3035): add kimi-code detection and flag to review workflow
The kimi-code reviewer lane was declared in REVIEWER_LANES, documented in
docs/COMMANDS.md, resolved via --kimi-code, and functional when reached —
but review.md's detect_clis hardcoded 11 of 12 lanes (no kimi probe) and
the flag-parse list omitted --kimi-code. /gsd:review --kimi-code could
never reach SELECTED_REVIEWERS.
Added command -v kimi detection and the --kimi-code flag to the review
workflow's CLI detection and flag-parse steps.
* chore(#3035): backfill changeset PR number 3115
