chore: remove Tauri, replace with Gossamer across docs and config

Tauri mobile config removed (gossamer.conf.json already present).
CLAUDE.md and README updated to reference Gossamer as the desktop/mobile
framework — own stack, linear type safety, no upstream dependency risk.

 ### Mobile Development
 
 **No exceptions for Kotlin/Swift** - use Rust-first approach:
 
-1. **Tauri 2.0+** - Web UI (ReScript) + Rust backend, MIT/Apache-2.0
+1. **Gossamer** - Web UI (ReScript) + Ephapax/Zig backend, PMPL-1.0-or-later (own stack)
 2. **Dioxus** - Pure Rust native UI, MIT/Apache-2.0
