Preserve all windows/workspaces on close, not just the last one

[Jordy098]

Summary

• Terminal blocks already persist their cwd (cmd:cwd meta, set via the OSC 7 shell-integration handler) and restore it when their shell relaunches — but that only helps if the Block/Workspace survives in the DB.
• Closing a window while other windows are still open (or with window:savelastwindow off) always deleted that window's workspace/tabs/blocks on close, discarding any persisted cwd along with it. Only a single-window full app quit reliably survived a restart.
• Adds a new setting window:restoreallwindows (default true) so every window is preserved on close, not just the last one, letting all previously-open terminal paths come back after a full app restart.

Test plan

• Open 2+ windows, cd to different directories in each terminal block and let the prompt render (fires OSC 7 → cmd:cwd)
• Close one window via the close button (not full quit) — its workspace should remain in the DB instead of being deleted
• Quit the app fully and relaunch
• Confirm all windows reopen with their terminals in the same working directory as before
• Repeat with window:restoreallwindows set to false to confirm the legacy single-window behavior still works

Walkthrough

This PR introduces a new boolean configuration key, window:restoreallwindows, which controls whether all open windows are preserved and restored on next launch. The change adds the key to the Go settings struct, config key constants, default settings JSON, JSON schema, TypeScript type definitions, and documentation. The window close handler in the Electron main process is updated to compute window preservation based on this new setting in combination with the existing window:savelastwindow setting.

_{🐰 A whisker-twitch of a config so small,
One bool to save the windows, one and all,
Schema, types, and docs align,
Close handler learns a new design,
Hop along, the settings stand tall.}
