v0.5.1

What's new

Features

• Session hydration — restarting rum restores the full conversation in the activity feed (user messages, assistant text, thinking, tool calls with output) instead of just showing a message count
• Input history on restart — up-arrow recalls previous prompts from the loaded session
• Mouse scroll — scroll wheel navigates the activity feed
• Shift+Up/Down — keyboard shortcut for feed scrolling

Fixes

• Reliable cancellation — escape stays effective while a tool is running (no longer falls through to clear-input after the first press)
• Queue ordering — queued commands and messages process in the order they were entered
• Restore input on cancel — cancelling while a message is queued puts it back in the input field
• Compact respects cancel — /compact checks the cancel token before and during execution
• Deferred compact dispatch — /compact typed while the agent is running waits for the current turn to finish instead of racing with it
