rafctl v0.4.0 - Sessions, HUD, Polish

What's New

Session Monitoring (Epic 14)

• rafctl sessions command to list recent sessions with duration, messages, tools, errors
• rafctl sessions <id> for detailed session breakdown with tool usage stats
• rafctl sessions --today to filter today's sessions only
• rafctl watch for live real-time session monitoring with file tailing
• Agent/Task call tracking with subagent types and durations

Native Rust HUD Plugin (Epic 15)

• rafctl-hud standalone binary implementing Claude Code's statusLine protocol
• Profile-aware display showing active rafctl profile in statusline
• Context window percentage with color-coded progress bar (green/yellow/red)
• Git branch, session duration, tool/agent counts display
• rafctl hud install [profile] to configure HUD for a profile
• rafctl hud uninstall to remove HUD configuration
• rafctl hud status to check HUD installation status
• Zero external dependencies (no Node.js required)

Polish & Hardening (Epic 16)

• Security: API key input now hidden (uses rpassword to mask input)
• Reliability: API requests use 30-second timeout
• Reliability: Global config uses atomic writes (prevents corruption)
• UX: New --yes / -y flag for profile remove to skip confirmation
• UX: Confirmation prompt before removing profiles (safety feature)
• Errors: New ProcessSpawn and NoDefaultProfile error variants
• Code: Refactored handle_run with extracted helper functions
• Code: New core::constants module for centralized configuration

Technical

• Added notify crate for filesystem watching (live session monitor)
• Separate binary target for rafctl-hud (src/bin/rafctl-hud.rs)
• New hud module with stdin protocol parser and renderer
• New core::transcript module for parsing Claude Code JSONL transcripts
