I have basically the same workflow. Planning mode has been the game changer for me. One thing I always wonder is how do people work in parallel? Do you work in different modules? Or maybe you split it between frontend and backend? Would love to hear your experience.

I plan out N features at a time, then have it create N git worktrees and spawn N subagents. It does a decent job. I find doing proper reviews on each worktree kind of annoying, though, so I tend to pull them in one at a time and do a review, code, test, feedback loop until it’s good, commit it, pull in the next worktree and repeat the process.
