Desktop desktop-v0.2.1

Fixes

• Code blocks lost their text color in light mode; fixed, and code the model sends without proper fencing now gets boxed with a copy button too.
• Effort slider markers were invisible in light mode.
• Danger-zone rows (deactivate/delete account) had cramped spacing.

Added

• Confirm dialogs for deactivate account, delete account, reset settings to defaults, and clear local cache.
• Skills now only apply when explicitly invoked with /<skill-name> in a message, instead of every installed skill silently affecting every conversation forever.
• Voice transcription is now gated by plan.

Changed

• Simplified the onboarding screen.
