Selector v1.3.0

## Selector v1.3.0 Enterprise-grade security and cloud features come to the free project launcher. ### Added - **Per-project Cloud Backup** — New cloud button on each project row. One click to create an encrypted snapshot with full version history. - **Remote SSH Launch** — Start Claude Code sessions on remote servers directly from your project list. - **SSH & Backup Add-ons** — Available independently on any licence tier. ### Security - **Compile-time Key Protection** — Cryptographic keys encrypted into the binary at build time. Nothing sensitive in plain text. - **macOS Keychain Storage** — Licence credentials moved to the system Keychain with seamless automatic migration. - **Tamper-resistant Usage Tracking** — Usage data cryptographically signed to prevent manipulation. - **Clock Manipulation Detection** — Detects system clock changes to prevent grace period abuse. - **Premium Feature Gating** — All premium features verified natively before execution. - **Hardened App Permissions** — Application entitlements reduced to the absolute minimum required. ### Changed - SSH and Backup buttons now appear per-project for quicker access, rather than in the header bar.
