From 25836e27b961ace4049dd999375a98c780aef45a Mon Sep 17 00:00:00 2001 From: Michael Freno Date: Sun, 26 Apr 2026 09:45:10 -0400 Subject: [PATCH] FRE-680: Initial project scaffold with auth & API client - Set up Go module with Cobra CLI skeleton - Implemented login/logout/session commands with 2FA support - Created ProtonMail API client with rate limiting - Added config management for ~/.config/pop/ - Configured CI/CD pipeline with GitHub Actions - Added Makefile for build/test/lint targets Files: - main.go, go.mod, go.sum - cmd/root.go, cmd/auth.go - internal/auth/session.go -
