This adjusts linux to follow a similar model to windows with a discrete archive
(zip/tgz) to cary the primary executable, and dependent libraries. Runners are
still carried as payloads inside the main binary

Darwin retain the payload model where the go binary is fully self contained.

Some users are experienging runner startup errors due
to not having these msvc redist libraries on their host

We update the PATH on windows to get the CLI mapped, but this has
an unintended side effect of causing other apps that may use our bundled
DLLs to get terminated when we upgrade.

The zip file encodes the OS and architecture, so keep the short exe name

This will make it simpler for CI to accumulate artifacts from prior steps

Now that the llm runner is an executable and not just a dll, more users are facing
problems with security policy configurations on windows that prevent users
writing to directories and then executing binaries from the same location.
This change removes payloads from the main executable on windows and shifts them
over to be packaged in the installer and discovered based on the executables location.
This also adds a new zip file for people who want to "roll their own" installation model.

Flesh out our github actions CI so we can build official releaes.

* remove `-w -s` linker flags on windows

* use `zip` for windows installer compression

Also fixes a few fit-and-finish items for better developer experience

This will be useful for our automated test riggig, and may be useful for
advanced users who want to "roll their own" system service

This focuses on Windows first, but coudl be used for Mac
and possibly linux in the future.
