Subject: [PATCH] fix(devin): probe %APPDATA%\devin so Windows sessions are
 indexed by default
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

DevinAdapter::new() only probed XDG (~/.local/share/devin), the XDG env
override and macOS' ~/Library/Application Support/devin. Devin Desktop on
Windows keeps its sessions.db at %APPDATA%\devin\cli\sessions.db, so the
default instance found no library and Devin sessions never showed up —
only a manually added custom location worked around it.

Add the AppData/Roaming candidate (derived from home_dir(), same
convention as cursor_ide so WAKE_HOME redirection keeps working). The
candidate is probed unconditionally like app_support, which keeps the
XDG form first in the order and makes the resolution testable on every
platform.
