Show HN: Instant branch management for AI-native development

Peek (v420) eliminates the context-switch tax when reviewing AI-generated code or working across multiple branches.

What it does: - Switch branches in 87ms without restarting dev server - Auto-stash on discard (`peek recover` to restore) - Federate multiple repos (`peek fed link backend ../api`) - Built-in AI context copying (`peek ctx src/`) - Self-healing with `peek doctor --fix`

What changed in v0.4.2: - Added reflink/hardlink capability detection - Lockfile divergence handling for node_modules - 20 real-world workflow docs - Complete PEEK-XXX error catalog

Tech: Git worktrees + HMR + write-ahead log for crash recovery. Works with Vite and Next.js.

Would love feedback from teams using AI agents in their workflow, or contributors who wish to add net positive gains to this.
