Compare view, session history, and snapshot/UX upgrades - #15

Conversation
- Split/compare view: two live agents side by side with a resizable divider; the compared pair is a remembered, explicit choice. - Session history: closing an agent archives its conversation instead of deleting it; a History panel reopens any past conversation (search + grouping). /clear still forgets. - Snapshots: group by project + search, per-group collapse (persisted), AI-generated unique titles when unnamed, direct manual capture. - Rail badges act as unread counts that clear when the panel is opened (persisted). - Closable last agent with an empty state that shows the chat background. - Import disabled when no agent is open. - App icon wired across exe/taskbar/window; added a crash logger.
Reconcile README, CHANGELOG, and session-persistence docs with the shipped behavior: compare/split view, session history (archive on close), snapshot grouping/search/collapse + AI naming, unread rail badges, closable last agent + empty state, persisted panel state, and the app icon. Fixes the stale "last agent can't be closed" and "snapshots are in-memory only" notes.

Summary
This PR adds several capabilities to MandoCode Desktop centered on working with multiple agents and never losing your work. Everything below is user-facing; the shared MandoCode engine is untouched.
What's new
Compare two agents side by side
You can now view two agents at once in a resizable split, to compare what each is producing in real time. The two agents being compared are a deliberate, remembered choice — switching to other tabs doesn't disturb the comparison, and a draggable divider adjusts how much space each side gets.
Session history — reopen closed conversations
Closing an agent used to permanently discard its conversation. Now closed conversations are kept and can be reopened at any time from a new History panel — they come back with their full transcript (and the agent's memory, when the model supports it). The panel groups conversations by project and is searchable. (Explicitly clearing a conversation still forgets it for good; only closing changed.)
Snapshot improvements
Snapshots are saved AI-written summaries of a conversation that can be carried into another agent.
Notifications that behave like notifications
The number badges on the History and Snapshots icons are now unread indicators: they show how many items are new since you last opened that panel and clear when you open it, rather than always showing a running total.
Close the last agent
The app no longer forces at least one agent to stay open. Closing the final agent leaves a clean empty state (showing your chosen chat background) with a one-click way to start a new agent. Actions that only make sense with an agent open (such as importing a snapshot) are disabled until one exists.
Application icon
The app now has a proper branded icon across the taskbar, window title bar, and File Explorer.
