Release on GitHub

Added

• Persistent scrollback - the SQLite+FTS5 history store is wired into pane lifecycle, keyed by stable attachment_id (schema v2; pre-v2 rows dropped as unrecoverable). The newest history_lines rows are restored into each pane’s scrollback on restart and back pane-read across restarts.
• history_lines setting - caps persisted scrollback per pane (default 10 000, clamped 100–100 000) in Settings → Terminal.
• History search - the terminal search bar gains a Live/History scope toggle; History mode runs FTS5 queries against the pane’s persisted scrollback and lists matching lines (click copies to clipboard).
• Workspaces - named pane sets (up to 8) with keep-alive panes: switching hides/shows grids instead of killing PTYs, so background commands keep running. Add/switch/close/rename via the sidebar’s Workspaces section (Ctrl+PageUp/Ctrl+PageDown to switch); saved to user://workspaces.json, with one-shot migration of the legacy layout.json (replaces the LayoutManager autoload). Concept captures and agent events keep routing from hidden workspaces.
• Sidebar polish - content margins (right ≈ scrollbar width), measured section heights that never truncate rows, icon+text action buttons (Settings/Reset/Search), and active-row accents across the workspaces, profiles, and panes sections.
• Profile rename - double-click a user profile in the sidebar to rename it inline (persisted, dedupe-suffixed like profile creation).
• Live pane-API smoke - scripts/smoke-pane-api boots the GUI headless with sandboxed user data and drives new-pane, pane-status, inject, pane-wait, pane-read, broadcast, pane-run (exit code), and kill-pane end-to-end, plus the event socket’s subscribe/eventsPoll fan-out; wired into ci-check and the CI gut-tests job.

Changed

• History retention trims the oldest rows beyond history_lines amortized over every 100 committed lines.
• start_shell no longer attaches a history store keyed by the per-node id counter (rows collided across panes and orphaned across restarts).
• pane-run executes commands through the configured shell (<shell> -c <command>) - compound commands (&&, pipes, globs) now work; the command is passed as a sanitized argument (shell_args), never as the program itself. Empty commands are rejected.
• Clicking any pane makes it the active pane - the status bar and sidebar accent follow. Only terminals take keyboard focus; read-only panes (Reasoning, code viewer, file tree) swallow keys, so typing no longer reaches a terminal you just left.
• New workspaces start as a blank slate instead of auto-spawning a terminal.

Fixed

• Pane API unreachable: pane-read, pane-status, pane-run, pane-wait, and broadcast were never registered on the GUI IPC server, so every CLI call returned Unknown method.
• Targeted pane API calls always failed with “not found”: paneRead/paneStatus/paneWait guarded on has_method("_terminal"), but _terminal is a property, not a method. Guards now check is TerminalPane.
• Toasts rendered half-hidden under the status bar - they now float above it.
• The docs site could bake Hugo’s own README as the project overview - the deploy now extracts only the hugo binary and smoke-checks the baked overview.
