mvnd ignores -b (--builder) and -T (--threads) parameter

### Affected version

1.0.3

### Bug description

Maven Daemon prefers Takari smart builder by default.
The problem is that it ignores explicitly configured builder on the command line or in the `.mvn/maven.config`.
E.g. it's not possible to use https://github.com/maven-turbo-reactor/maven-turbo-builder adding it to `.mvn/extensions.xml` in combination with neither CLI `-b turbo` nor `.mvn/maven.config` `-bturbo`.

According to ` mvnd -h | grep builder` there are two ways for it:
```
-b,--builder The id of the build strategy to use
-Dmvnd.builder=;-b,--builder The builder implementation the daemon should use.
takari-smart-builder extension, remain buildable with mvnd (where use of this extension would cause issues). Value is expected as comma separated pairs.
Default: io.takari.maven:takari-smart-builder
```
The second `-Dmvnd.builder=turbo` works fine.

Same problem with `-T` (`--threads`) which is always defined as default `-T1C` (`-Dmvnd.threads=6` works fine). But the `mvnd -h` claims both should be supported

Reproduce the reported behavior with mvnd 1.0.3 using -b/--builder and -T/--threads, both on the command line and through .mvn/maven.config, then compare it with the working -Dmvnd.builder and -Dmvnd.threads forms. Trace the argument handling and verify that the documented options select the requested builder and thread count without relying on the system defaults.
