feat: dev pipeline — multi-project git tools, git_commit, git_push

git_status/log/diff gain a `project` param (same aliases as aider_run:
cortex/aether_api/aether_frontend/aether_container). Default is Cortex
for backward compat.

New git_commit and git_push tools complete the review→commit→push loop:
aider_run(auto_commit=False) → git_diff → git_commit → git_push.
Both admin-only, confirm-required, high risk.
