Enhances the native right-sidebar Files tab rather than replacing it: each row gets an @ reference button that inserts the canonical path mention into the composer, plus a size column, a sortable modification-time column, and a status dot for untracked, unstaged and staged files. Below the tree a git bar shows the branch with ahead/behind counts and expands upward into the 20 most recent commits, with a repository selector when a workspace has independent repositories in subdirectories. A header search box walks the workspace recursively and can open a result or expand the tree at it, preview tabs offer reveal-in-tree and one-click @, the tree is keyboard navigable with ARIA tree semantics, and a right-click entry on the Files tab switches back to the native tree at runtime.
