v0.2.4

What's New

Settings overhaul

• Presets tab redesigned as master-detail: list on the left, editor on the right
• Persona icon picker: SF Symbol popover replaces the plain text field
• Tab persistence: Settings remembers the selected tab across theme changes (previously reset on every appearance switch)
• Console toolbar button now hidden on Settings / Reports / Status routes; inspector auto-closes when navigating away from chat

Bug fixes

• ⌘, crash (#33): Opening Settings via the keyboard shortcut hit a missing-environment assertion. The Settings scene now receives the same environment objects as the main window.
• Keychain calls moved off main thread to satisfy Thread Performance Checker

Commits

• feat(settings) — presets master-detail, icon picker, tab persistence; fix keychain + console toolbar
• fix(settings) — inject environment into Settings scene so ⌘, doesn't crash (#34)
