chore: upgrade sacp to 11.0.0 stable and agent-client-protocol-schema to 0.11

- Upgrade sacp/sacp-tokio from 11.0.0-alpha.1 to 11.0.0 stable
- Upgrade agent-client-protocol-schema from 0.10 to 0.11
- Rebase vendor/sacp-tokio patches (kill_tree, CREATE_NO_WINDOW, stderr
  truncation) onto official 11.0.0 baseline
- Adapt renamed types: FileSystemCapability → FileSystemCapabilities,
  KillTerminalCommandRequest/Response → KillTerminalRequest/Response
