TUI plugins using the deprecated api.command API keep working while you migrate to api.keymap

Fixes

• CoreProvider configs and API responses now accept models marked as active.
• CoreRead tool permission rules now match worktree-relative paths, so read allowlists and denylists apply correctly.
• CoreWorkspace-routed HTTP API endpoints no longer reject valid directory and workspace query params.
• TerminalStartup errors now report every failed bootstrap request instead of only the first one.
• TerminalOpening a session no longer crashes when the messages request fails.
• DesktopOlder migrated sessions with missing diff file details load again.
• DesktopOlder migrated sessions with missing diff patches load again.@OpeOginni
• SDKthrowOnError: true now throws a real Error with the server message and preserves the response body in cause.
• ExtensionsProvider plugins can no longer mutate shared provider model state for the rest of the app.
