feat(git): auto-regenerate + commit codegen drift before push (#632)

A project that checks in generated artifacts (RoboCo's lifecycle renders,
verb tables) drifts whenever their source changes. The agent pre-submit gate
(make gate) omits foundation-check, so drift is invisible at the desk and only
fails on CI's drift gate — a failure with no link back to the task, which made
one live task thrash 8 revision rounds.

New per-project codegen_command (migration 078): run in the task's worktree
right before push, and any drift committed into the same push, so CI never
sees stale artifacts. Fail-open — a broken/timeout codegen command logs and
lets the push proceed (CI's drift gate is the safety net); a null command
(every project without checked-in codegen) is a pure no-op. Hooked at both
push_branch (open_pr's first push, the PR head CI grades) and push_task_branch
(later re-pushes). RoboCo sets codegen_command='make codegen' (a new Makefile
target — the write counterpart to foundation-check's read) via the panel.
