* fix(mobile): use exact directory matching for session grouping The new mobile sessions sheet used startsWith prefix matching to assign sessions to projects, which caused child-directory sessions (e.g. /root/repos/opencode) to be grouped into parent projects (e.g. /root/repos). Switch to exact directory matching (project root or registered worktree paths only) to match the desktop sidebar behavior. Also exclude sub-agent sessions (those with parentID) from the totalSessions badge count so the displayed number reflects only top-level sessions. * fix: align mobile session project matching --------- Co-authored-by: lilyzhaun <lilyzhaun@users.noreply.github.com> Co-authored-by: Bohdan Triapitsyn <artmore@protonmail.com>
