`dx component add` does not correctly suggests --package flag when in workspace

**Problem**

When trying to `dx component add` in a workspace with multiple binaries, the `--package` flag is suggested. It would be very nice to understand _at what position_ that flag is expected:

```
$ dx components add progress

ERROR dx components: Failed to find binary package to build.
You need to either run dx from inside a binary crate or specify a binary package to build with the `--package` flag. Try building again with one of the binary packages in the workspace:
- distrox-cli
- distrox-gui-desktop

$ dx components add progress --package distrox-gui-desktop
error: unexpected argument '--package' found

tip: to pass '--package' as a value, use '-- --package'

Usage: dx components add ...

For more information, try '--help'.
$ dx --package distrox-gui-desktop components add progress
error: unexpected argument '--package' found

Usage: dx [OPTIONS]

For more information, try '--help'.
$ dx components --package distrox-gui-desktop add progress

Usage: dx components [OPTIONS]

$ dx components add --package distrox-gui-desktop progress
error: unexpected argument '--package' found

**Steps To Reproduce**

Steps to reproduce the behavior:

- Have a workspace with multiple binaries
- `dx component add `

**Expected behavior**

Suggestions what exact command to execute.

**Environment:**

- Dioxus version: 0.7.3
- Rust version: 1.93.1
- OS info: NixOS 25.11
- App platform: desktop fullstack

Start by reproducing `dx components add progress` in a workspace with multiple binary packages, then locate the CLI entry point and argument definition for `components add`. Check how the suggested `--package` placement is generated and verify that the documented invocation is accepted by the command parser.
