Add Go project scaffold for Wails v2 SSH/Telnet/RAW TCP client

- go.mod with Wails v2.9.2, x/crypto, go-sqlite3, go-keyring, uuid - cmd/app/main.go: Wails entry point (Nexus Terminal, 1400x900, #1a1a2e) - internal/app/app.go: lifecycle (Startup/Shutdown/DomReady) - internal/models/models.go: full model definitions (Profile, SSHConfig, TelnetConfig, RAWConfig, SessionInfo, KnownHost, AppPreferences, etc.) - internal/models/defaults.go: default values and NewProfile factory - internal/validation/validation.go: thorough field-level validation - frontend/embed.go: embedded frontend assets - Updated existing storage, secrets, config to match new model structure
