local-app: Make the version string more CalVer compliant

[ajhalili2006]

Is your feature request related to a problem? Please describe

I want to maintain my own builds of the Local Companion app to more arches for Linux users (hint: linux/386 and linux/arm), but the issue is the official builds aren't CalVer compliant, though I need to do some guesswork on getting the version string from its --version command.

Describe the behaviour you'd like

Make the version string for the Local Companion to be SemVer compliant, not necessarily follow self-hosted release schedule. Optionally also provide an API for retriving new versions.

Describe alternatives you've considered

While I can technically scrape the binary version from the official builds through some shell script magic, it would be a bit of a nightmare.

Additional context

Originally asked in Discord about setting the Dversion flag for building Local Companion from source with Leeway.

[ajhalili2006]

Technically speaking, while I can scrape it from the official ones, I want to also provide where commit in the upstream repo at the time the build happens on my own builds, which kinda painful because I think the Local Companion CLI is being built in part of daily prod deployments, I guess.

[ajhalili2006]

I updated the issue description and title to reflect that self-hosted releases are versioned as CalVer, not Semver.
