Tau 0.4.5

New

• Edit prompt templates, context files, and skills from the TUI sidebar: click a resource row to open it in an in-app editor, save with Ctrl+S, and close with Escape.
• Run /system to see where each system-prompt section came from, with prompt files, project instructions, skills, extensions, and runtime values grouped by origin.
• Isolate credentials, sessions, preferences, and caches per profile with the TAU_HOME environment variable.

Changed

• Show resume history as project columns with the current project first and other directories grouped separately.
• Add an ask-user-question example extension that demonstrates interactive prompts from extensions.

Fixed

• Order forked session trees by real history so alternate branches appear after the event where the fork started instead of collecting at the bottom of /tree.
• Resolve @file and shell ! path completions at the caret, including @ mentions in the middle of a prompt or inside skill and template arguments.
